Half Duplex vs. Full Duplex

When evaluating Power over Ethernet switches, it’s important to understand full duplex and half duplex. When a switch is connected to an IP device, information is transferred in both directions. The switch sends information to the endpoint device and vice versa. Full duplex (FDX) switches allow for the simultaneous transmission of information between the switch and the endpoint. In a half duplex (HDX) system, communication flows in one direction at a time.

For example, let’s say two files need to be exchanged. One file is at the head end (switch end), and the other is at the endpoint. The two files are 150Mb in size, and the switch can deliver 100Mbps, full duplex. In this scenario, it would take 1.5 seconds to transfer BOTH files to their destinations.

Let’s now analyze this scenario from a half duplex perspective. In this situation, the first file must be transferred before the other can be sent. Assuming the same file size and the same delivery of 100Mbps, the time required to transfer the two files is approximately doubled. Both files are transferred at the same speed, but not simultaneously, creating a very different overall experience.

The above example is a bit of an oversimplification of a real-world example. Full duplex and half duplex switches will vary in performance. Collision management, the directionality of traffic, the number of endpoints in a network, and cable length/type will also have an impact. It is not uncommon to see performance of less than half of a full duplex network.

A half duplex system can be compared to the “push-to-talk” nature of a walkie talkie. When the button is pressed, the receiver is turned off, and the transmitter is activated. When the button is released, the transmitter is turned off, and the receiver is turned back on. The device cannot transmit and receive simultaneously. A full duplex system is like talking on the telephone, in which both parties can speak and listen at the same time.

The entire NVT Phybridge CHARIoT Series of products are full duplex switches. Data is transferred simultaneously from the switch to the endpoint, and vice versa, to ensure optimal network performance and speed.

Symmetrical vs. Asymmetrical Bandwidth

Like full duplex and half duplex, symmetrical and asymmetrical bandwidth will play a significant role in the network’s overall performance and reliability. A switch that can deliver 100Mbps symmetrical, full duplex can transmit and receive at a rate of 100Mbps. Even if it is full duplex, a network switch with asymmetrical bandwidth cannot send AND receive at 100Mbps. Asymmetrical switches will use an uneven split to transmit at 70Mbps and receive at 30Mbps, for example.

Using the same example of moving two 150Mb files, a 100Mbps symmetrical, full duplex switch will deliver both files in 1.5 seconds. A 100Mbps asymmetrical half duplex switch with a 70/30 split will take 7.14 seconds to deliver both files. Even though both devices can be marketed as a 100Mbps switch, real-world performance is significantly different.

The NVT Phybridge CHARIoT series of products all have symmetrical bandwidth capabilities, ensuring fast and consistent data delivery through the network.


In addition to transmission speed, latency also plays a significant role in network performance and service quality. Latency is the time it takes a piece of information (a packet) to reach its destination. Latency may not be as crucial for certain endpoints, such as data terminals. However, for real-time applications like voice calls or live video monitoring, low latency is critical to ensure good user experience.

To illustrate latency, we tested our long reach Ethernet over Coax switch against a competing product. Both switches were tested at 100Mbps, symmetrical, full duplex over 2,000ft of RG6 cable.

Latency was tested using the Siama GENEM-X 10G Ethernet/IP Test Application at various frame sizes ranging from 64 bytes to 1518 bytes. The average delay, or latency, of the NVT Phybridge CLEER24 switch, was 64 microseconds. The average delay of the competing product was 4,685 microseconds, which is 73-times more latency that the CLEER24 switch. See the full performance comparison between these two products.

Even at 2,000ft, NVT Phybridge Power over Ethernet switches have extremely low latency, on par with standard reach Ethernet solutions from market leaders like Cisco. Many long reach Power over Ethernet solutions on the market have higher latency levels, which are not suited to support real-time applications.


Finally, there is the issue of noise, also known as crosstalk. Crosstalk occurs when a signal transmission results in undesired electromagnetic waves that interfere with surrounding equipment or wiring.

Noise production makes a big impact on large deployments where there is a lot of equipment and cabling in one physical space. This issue can be overlooked when testing equipment with just a few devices. However, as the deployment size increases, so does the noise produced, and therefore the interference with other devices. As a result, devices will slow and experience packet loss.

NVT Phybridge Power over Ethernet solutions are FCC Class B certified and produce very minimal noise interference. This makes our equipment safe and effective, even around extremely sensitive devices like pacemakers. Our long reach Power over Ethernet switches are used onboard many luxury cruise ships to enable thousands of endpoints inside the noisy metal walls of a ship’s networking closets – without issues. This makes our solutions very scalable, especially for large scale deployments with many endpoints.

There are several Power over Ethernet switches on the market, and they are far from equal. Clever marketing tactics can sometimes hide the real story behind a Power over Ethernet switch’s expected performance. It’s important to understand what the numbers mean and how that translates into a better experience.

Managed vs. Unmanaged Switches

Managed vs. Unmanaged Switches

What is a Network Switch?

There are two types of network switches: managed and unmanaged. It is important to understand the differences between managed vs. unmanaged switches when setting up a network.

A network switch is a piece of networking equipment that connects devices on a local area network. The network switch is a core component of network infrastructure and facilitates the transmission of data between connected devices. Unlike a network hub (which sends all data to all ports), a network switch only sends data to the device it is intended for.

Managed vs. Unmanaged Switches

Unmanaged Network Switch

An unmanaged network switch is often referred to as a plug-and-play type network solution. This is largely due to its fixed configuration and minimal setup requirements. As the term “plug-and-play” suggests, IT teams can quickly and easily incorporate unmanaged switches into the local area network.

Unmanaged switches are most commonly used for smaller networks, or to extend an existing network with additional ports. Due to its simplicity and lack of customization, unmanaged switches are usually available at a lower cost when compared to managed network switches.

Managed Network Switch

Compared to an unmanaged switch, managed switches offer more enhanced network control features and configuration options at the cost of complexity. Setting up a local area network using managed switches will require a skilled network administrator. This is especially true when looking to get the most out of the device’s capabilities.

A managed network switch provides network administrators with the ability to manage, configure, and monitor local area network settings using a graphical user interface or command line. Each port can be configured separately to maximize the performance of the network and the endpoint devices. Troubleshooting and monitoring are simpler and can be done remotely.

Managed network switches also provide significant security benefits. Network administrators can monitor and manage network traffic in real-time. This provides a faster and more effective response to active security threats.

Managed switches also support VLAN segmentation. This will allow administrators to separate network applications connected on the same physical network without installing multiple sets of cables and networking equipment. Managed switches are usually much higher in cost due to their enhanced feature set and robustness.

Do I Need a Managed or Unmanaged Switch?

The type of network switch you need will largely depend on what it will be used for and what size of the environment. Unmanaged network switches are ideal for smaller LAN environments, such as a home, small business, or single retail shop. Unmanaged switches are also ideal for those who want to quickly and easily set up a local area network.

Managed switches are more suited for medium and large enterprises, or those who need to manage network traffic and accessibility. Many network engineers and managers would suggest the use of managed switches for networks with a large number of users. Managed switches are also ideal if clients, partners, or other external individuals need to gain access to your network.

Power over Ethernet Explained

What is Power over Ethernet?

Power over Ethernet (PoE) is the process of sending electrical power and data over copper wire.

The combination of data transmission along with power supplying hardware onto the same RJ45 Ethernet connector allows for the transmission of power over the network cabling. Power over Ethernet networks can source power at the network switch side or at a PoE injector to add power to an existing data line.

How Does Power over Ethernet Work?

Power over Ethernet is a process where devices known as power sourcing equipment (PSE) provide a direct current (DC) voltage over a standard Ethernet cable to another connected device known as a powered device (PD). This allows for the powering of devices without the need for a local power source at the device location or having to run a separate cable for power.

Power over Ethernet Evolution

Before Ethernet communications, devices like cameras required a signal cable to transmit the image back to a recorder. These devices also required local power supplies to provide power. Because cameras and similar devices are often installed in locations where local power may not be available, companies started running a mix of signal and power cables with a power supply transmitting power from the head end recorder location.

Through further development into signaling and power technologies, cameras started using multi-pair UTP cables, like CAT5, to send a mix of signaling and power. Signaling was sent on one or two of the four pairs of a CAT5 cable, and power transmitted on the remaining two pairs. This helped to simplify installations, as fewer cables were required to accomplish the same task.

When endpoint signaling moved away from analog transmissions to IP, this capability was lost. Then in 2003, Power over Ethernet was created and standardized by the Institute of Electrical and Electronics Engineers (IEEE).

Power Over Ethernet Standards

The Institute of Electrical and Electronics Engineers (IEEE) is the governing body that creates standards for Ethernet and other data communications. The first governing document created for Power over Ethernet was 802.3AF, which states that compliant Power over Ethernet switches deliver 15.4W of power to guarantee a delivery of 12.95W at the endpoint.

Improvements to this standard came in the form of 802.3AT, also known as PoE+, which states that Power Sourcing Equipment can provide 30W of power to ensure 25.5W at the endpoint. To guarantee a successful negotiation, both the switch and the endpoint device must be IEEE compliant. However, some device manufacturers have created their own implementations of Power over Ethernet.

There are three main techniques for transmitting power over Ethernet cabling. These are Mode A (also known as common-mode data pair power), Mode B (spare-pair power), and 4PPoE (4-Pair power). With Mode A the power is provided on the same cable pair as the data pairs used in a 10Base-T or 100Base-TX transmission. With Mode B the spare pairs are used and with 4PPoE all 4-pairs of the Ethernet cable are used for power transmission. Below are the specifics of each mode.

PoE Mode Ethernet Cable pairs utilised Pin allocation
Mode A Data Pairs. Pins 1, 2 & 3, 6 Pins 1, 2 = Positive Voltage (DC+)

Pins 3, 6 = Negative Voltage (DC-)

Mode B Spare Pairs. Pins 4, 5 & 7, 8 Pins 4, 5 = DC+

Pins 7, 8 = DC-

4PPoE All 4 Pairs Pins 1, 2 & 4, 5 = DC+

Pins 3, 6 & 7, 8 = DC-

These have been standardized by the Institute of Electrical and Electronics Engineers (IEEE) under the Ethernet Standard 802.3. The first being standardized in 2003.

IEEE Standard PoE Mode Supported Year of Standardisation
802.3af Mode A, Mode B 2003
802.3at Mode A, Mode B 2009
802.3bt Mode A, Mode B, 4PPoE 2018

Each IEEE standard depicts how the power is delivered, the voltage (V) supplied, and the wattage (W) available as can be seen in the below table:

IEEE Standard PoE Type DC Voltage output at PSE Power delivered by PSE Voltage Available at PD Wattage Available at PD PoE Mode Supported
802.3af Type 1 “PoE” 44-57V 15.4W 37-57V 12.95W Mode A

Mode B

802.3at Type 2


“High PoE”

50-57V 30W 42.5-57V 25.5W Mode A

Mode B

802.3bt Type 3


42.5-57V 60W 42.5-57V 51W Mode A

Mode B


802.3bt Type 4


41.1-57V 100W 41.1-57V 71W 4PPoE

There are varying names for these Power over Ethernet standards, as can be seen under the PoE Type heading in the above table but essentially, they all fall under the specified IEEE standards listed.

Power over Ethernet Class

The Power over Ethernet Class is reserved for powered devices (PD). The class specifies how much power the PD requires to function. There are currently 9 PoE classes ranging from 0 to 8. They are as follows:

Class Usage Wattage required at PD
0 Valid for Type 1 (802.3af) devices 0.44–12.94W
1 Valid for Type 1 (802.3af) devices 0.44–3.84W
2 Valid for Type 1 (802.3af) devices 3.84–6.49W
3 Valid for Type 1 (802.3af) devices 6.49–12.95W
4 Valid for Type 2 (802.3at) devices,
not allowed for 802.3af devices
5 Valid for Type 3 (802.3bt) devices 40W (4-pair)
6 Valid for Type 3 (802.3bt) devices 51W (4-pair)
7 Valid for Type 4 (802.3bt) devices 62W (4-pair)
8 Valid for Type 4 (802.3bt) devices 71.3W (4-pair)

In most cases, the datasheet of a PD will display the Power over Ethernet Class of the device or at least the IEEE standard it adheres to in the power, power consumption, or electrical sections.

Maximum Distance for Power Over Ethernet

Over the past 30 years, Power over Ethernet technology has seen incredible innovation. Initially, one of the primary downsides of Power over Ethernet was the limited reach of 328ft (100m). However, new PoE innovations, like those from NVT Phybridge, are pushing the limits of Power over Ethernet transmission over several cable types. For example, the NVT Phybridge CLEER24 is an enterprise-grade 24-port PoE switch that delivers power and data up to 6,000ft (1,830) over a single Coax cable. That’s 18 times farther than a standard reach Power over Ethernet switch.

NVT Phybridge Power over Ethernet

The enterprise-grade 24 and 48-port PoLRE® switches deliver power and data over a single pair of UTP cable (also known as Category 3 cable or voice-grade cable used for telephone wiring) with up to 1,200ft (365m) reach. The NVT Phybridge FLEX24 switch delivers power and data over 2 or 4-pairs of UTP cable (Category 5/6 cable) with up to 2,000ft (610m) reach.

Advantages of Power Over Ethernet

Power over Ethernet provides four primary advantages: lower infrastructure costs, fast and simple deployments, improved LAN design, and reduced e-waste.

Endpoint devices require two connections: data and electrical. The data connection allows communication with the network while the electrical connection powers the device. Separately installing both connections is costly and unnecessarily complicated, especially when considering the number and location of the devices across the organization. Power over Ethernet provides both connections using a single wire.

Many companies will install a Power over Ethernet switch fabric when modernizing from older, analog voice and security systems, or when deploying a new system. NVT Phybridge PoE switches provide numerous benefits:

  1. Lower infrastructure costs
  2. Fast and simple deployment
  3. Improved LAN design
  4. Lower e-waste

Lower Infrastructure Costs

Businesses looking to modernize from analog/digital devices to IP already have the most critical requirement, a proven and reliable LAN infrastructure. This cabling can be leveraged using NVT Phybridge Power over Ethernet technology to support IP endpoints. Organizations have been doing this for over ten years to ensure simple VoIP and security upgrades.

Companies are saving millions of dollars in network readiness costs while avoiding the unforeseen challenges that come with an enterprise-wide network overhaul. These cost savings are realized through significantly reduced labor, cabling, and construction costs, which are often reallocated into devices and applications to improve return on investment.

The extended reach capabilities significantly reduce IDF closet requirements – including space, power, cooling, and backup power – to reduce cost, network complexity, and to simplify network management. NVT Phybridge PoE switches are simple to deploy, configure, and manage. Deploying devices across multiple locations is easy, thanks to the repeatable, predictable, and scalable deployment methodology.

Fast and Simple Deployment

Deployments using Power over Ethernet technology are quick and easy, especially when leveraging network infrastructure that is already in the building. Simply install the PoE switch in the MDF closet, connect to the new or existing network cabling, and connect the device at the endpoint location.

Improved LAN Design

Organizations have the freedom to establish/maintain a physically separate Power over Ethernet network, or centrally converge to the core network using a single wire in a highly secure and controlled manner. This applies to both Cloud and on-premise solutions and significantly improves network security and performance. Quality of service is enhanced while ongoing network management is simplified as IT teams continue to manage the core business network while voice/security teams can handle these separate networks.

Additionally, as core business applications and data terminals (employee computers, Wi-Fi access points) continually require more and more bandwidth, network equipment will generally evolve every 3 to 5 years. By physically segmenting your PoE network, you can make changes to your core business network without impacting or disrupting your communication, security, and other systems.

Less E-Waste

By repurposing existing infrastructure and reducing/eliminating IDF closet requirements, organizations are significantly reducing the environmental impact of their digital transformations. Far less cabling and equipment e-waste is produced. NVT Phybridge Power over Ethernet switches are built with PowerWISE technology to ensure low energy consumption, power redundancy, and hot-swappable power supplies.

In 1990, networking equipment manufacturer, Kalpana, introduced the first multi-port LAN switch, which significantly enhanced Ethernet networks and paved the way for modern switch solutions. Cisco later acquired Kalpana in 1994.

For the next 10-15 years, the only devices connected to these networks were data terminals. During this period, the objective was to continually deliver an increasing amount of bandwidth to these data terminals, as demand for faster speeds increased.

Today, organizations are deploying an increasing number of internet-connected devices onto the local area network, including IP phones, IP wireless access points, and IP intercoms. These new devices are being layered on to a network that was designed for data terminals. However, IP and IoT devices have significantly different requirements than a traditional data terminal.

IP phones, for example, require real-time data delivery and are highly latency-sensitive. However, IP communication is being layered onto a switch fabric designed for near-time data delivery with an emphasis on delivering an increasing amount of bandwidth.

Given the technology available at the time, VLAN solutions were introduced to virtually segment the network. However, the local area network has become incredibly complex, difficult to manage, and costly.

Today, new switch innovations are available, and VLANs may no longer be the most effective strategy. NVT Phybridge switch innovations allow organizations to create a physically separate network for various IP devices and applications. Organizations can leverage any new or existing infrastructure to create a physically separate, robust, and secure PoE backbone for any smart device. Additionally, these networks can be centrally converged using a single wire in a highly controlled manner. We have helped many organizations leverage their existing point-to-point network topologies to achieve the same five 9’s of reliability that was experienced with analog systems.

This allows businesses to create LAN strategies based on the requirements of the endpoint device. Frost & Sullivan refer to this as the “outside-in approach” in the Modern LAN literature. Cisco refers to this as “intent-based networking”. Both refer to establishing a purpose-driven network that is specifically designed to support the application and endpoint being enabled. This strategy can provide amazing benefits to the end-user:

  • No compromise to the existing data network
  • Simple and fast modernization to IP
  • Reduced cost and business disruption
  • Secure and reliable PoE network
  • A network that is simple for IT teams to manage

Many hospitals that we have worked with prefer to establish physically separate networks for voice and emergency phone systems because they need to maintain 24/7 up-time to ensure safety. This kind of reliability and performance is available for any organization, not just those in healthcare.

Spend less of your digital transformation budget on infrastructure and more on the ROI-driving factors, such as the endpoints and applications that provide business value. Is your organization looking to modernize to IP or the Internet of Things? Let us help you simplify network requirements while creating a robust and reliable PoE backbone for any IP device.

The modern classroom is becoming a more connected and digital experience with new technologies to enhance security, productivity, and learning. It started with computer labs for student use, smart whiteboards in the classroom, and digital textbooks in place of old, beaten-up books with notes and drawings from past owners.

Technology in the classroom has provided a fantastic opportunity to expand and improve the curriculum. Computer labs helped educators prepare students for careers in computer programming, accounting, design, and more.

Today, the Internet of Things (IoT) provides even more opportunity to enhance education, from preparing students for future careers to improving safety and security measures. Internet-connected security cameras, blue light emergency phone terminals, and IP access control help make our schools as safe as possible.

However, infrastructure requirements continue to be one of the biggest challenges for educational institutions as they attempt to incorporate new technologies and IoT devices. Many operate in older buildings or on older campuses, making it extremely costly, complicated, and disruptive to rip-and-replace the existing infrastructure to support these smart devices.

Universities, specialized institutions, and school districts are simplifying the modernization to IP and the Internet of Things. Using Modern LAN principles and NVT Phybridge switch innovations, these institutions are transforming their existing cabling into a robust and secure IP backbone to support these intelligent, internet-connected devices. As schools try to do more with what they have, this no-compromise solution provides massive savings to ensure digital transformation projects easily stay within budget.

Endpoints and Applications are Just the Tip of the Iceberg

We hear a lot of stories from our customers and partners at tradeshows and other events. A common one is of organizations buying hundreds/thousands of IP devices when they have the available budget. However, the organization has yet to address network readiness requirements to support these devices. When they approach the network infrastructure, they discover many challenges and roadblocks that prevent them from modernizing altogether. Therefore, the IP devices remain in server rooms and storage closets for months, sometimes even years, while the organization addresses these requirements.

In the case of New Mexico State University, the team had purchased thousands of IP phones in preparation for its move from analog to IP. Project partners had recommended that the university rip-and-replace its existing voice infrastructure to support the new communication solution. Not only was the network incomplete at the time of purchase, but the network strategy was also unsuccessful. This was the roadblock that led to thousands of phones in storage.

Then the university discovered NVT Phybridge and changed its network readiness strategy. Using the PoLRE® switch, the customer transformed the existing voice infrastructure, that had effectively supported the current system for years, into an IP backbone. Using this new strategy, New Mexico State University saved over $1 million in infrastructure costs and accelerated the project by three years.

They say you can only see about 10% of an iceberg floating in the ocean. The majority is hidden below the water. As you plan your next digital transformation project, its crucial to understand your unique LAN challenges and requirements to support the IP endpoints and applications.

Let us help you create a simple, secure, and cost-effective network to support your IP devices and applications.

Is your company one of the thousands still relying on a Nortel CS1000 (CS1K) or another outdated analog phone system? Even as these systems become end-of-life, many organizations feel as though they cannot upgrade to the latest IP voice solution because the infrastructure requirements are too risky, complex, costly and disruptive to the business. However, new network design philosophies and Power over Ethernet (PoE) switch innovations are eliminating the traditional rip-and-replace requirement to simplify and accelerate the modernization to IP telephony and other applications; significantly reducing costs and improving return on investment.

The traditional approach to local area network (LAN) design was established when PC devices were the only endpoints being connected to the network. Today, organizations are expanding their LAN to not only support the core business, but also many supportive applications – including IP communication. Industry analysts at Frost & Sullivan recognized this trend and developed the Modern LAN Principles as an enhancement on traditional network design to effectively support IP and the Internet of Things (IoT). Together, Modern LAN design and NVT Phybridge innovations overcome these traditional infrastructure barriers.

Modern LAN Principles suggest viewing the network from an outside-in perspective. Instead of designing the network based on switch capabilities, Modern LAN design suggests first analyzing the requirements and purpose of the endpoint device and application. For example, IP phones require minimal bandwidth, can be powered using PoE switches, and are latency sensitive.

The NVT Phybridge PoLRE® (Power over Long Reach Ethernet) switch, with SmartPathPoE technology, enables Modern LAN design by transforming the existing voice network into a robust IP backbone for IP voice. By reusing the existing voice infrastructure that is point-to-point and physically separate from the core business network, organizations are creating a purpose-driven network specifically designed to support IP voice. The point-to-point topology ensures that packets from the real-time voice applications travel in order and on time, without contention or loss – providing best-in-class quality of service (QoS) and performance.

Maximize Return on Investment

Organizations are significantly improving return on investment as they leverage their existing voice infrastructure. These costs are reduced as no renovations or building modifications are required. Equipment costs are minimal as the cabling and equipment needed is reduced. Organizations can expect to reduce infrastructure costs by 50% – 80% which can be reallocated to ROI-driving devices and applications. Learn more >>

Simplify LAN Management

The PoLRE family of enterprise-grade PoE solutions extend data and power up to 1,200ft (365m) away from the application; that’s four times farther than standard Ethernet switches. The long reach capabilities often reduce/eliminate IDF closet requirements, further reducing project complexity and cost while creating a network infrastructure that is simple for IT teams to manage. Learn more >>

Cloud-to-Endpoint Made Simple

When organizations are planning to deploy a Cloud-based communication solution, they are often left with the responsibility of establishing the required local area network to support the system. These LAN readiness requirements are extremely high cost and often delay the project, sometimes indefinitely.

Instead of ripping out and replacing the existing and proven infrastructure, thousands of organizations are using Modern LAN design principles and NVT Phybridge PoLRE technology to establish a purpose-driven network for Cloud-based communication. The resulting network is physically separate and point-to-point; creating robust and cyber-secure pathways for each device. These smart pathways ensure optimal performance and reliability for any Cloud-based solution. Learn more >>

Enhance Cyber-Security

As IP communication and the Internet of Things (IoT) becomes more prevalent, cyber-security has become a top concern. In the connected world of the Internet of Things, each “thing” on the network represents a possible entry point for malicious activity.

Leverage the existing voice infrastructure to create a physically separate network for voice with the option to securely converge on-premise or in the Cloud using a single wire. The long reach capabilities of the PoE technology eliminates the need to install additional IDF closets; further reducing the number of possible entry points for malicious activity.

Ensure Your Cloud-Based IP Solution is Robust, Reliable and Secure

Organizations in all industries are moving to hosted, or Cloud-based, IP solutions for communication, security and other IoT applications. However, many organizations are faced with challenges as they attempt to effectively connect each IP endpoint to the application in the Cloud. The industry is starting to realize that the core issue has nothing to do with the endpoint or the application. The core issue is LAN topology and determining the best way to connect each IP endpoint to the D-mark (router) on-site, before connecting to the off-site application.

Cloud-based solutions are attractive because the organization doesn’t need to manage the application. The expectation is that modernizing to a hosted solution will be simple and quick. However, the Cloud provider is often not responsible for the local area network, leaving the organization with this large task. These LAN readiness requirements can significantly increase project complexity and risk – while stalling the deployment.

LAN readiness costs can quickly become the reason these projects are delayed, sometimes indefinitely. Many network providers will still recommend that the customer rip-and-replace existing infrastructure and layer the new IP solution onto the core data network. This requires a massive capital investment that the organization did not originally plan for. In addition, this approach negatively impacts the business through network downtime and brand risk from the disruption caused by the network overhaul.

Layering IP applications onto the primary data network also increases ongoing management costs and complexity for IT teams. This LAN strategy often results in system reliability and security concerns as more and more endpoints and applications are added. To effectively support a Cloud-based IP solution, it is critical to establish a robust and effective local area network strategy and topology.

Modern LAN Design – A Complete End-to-End Solution

The Modern LAN is an enhancement on traditional LAN design philosophies; developed by industry analysts at Frost & Sullivan. Modern LAN design synergizes the technological advancements of the Cloud with the reliability and performance of a robust and secure LAN topology. Modern LAN design solves the number one issue with hosted solutions; effectively connecting each and every IP endpoint on the local area network to the router.

Instead of ripping out existing and proven infrastructure, Modern LAN design suggests leveraging the existing point-to-point network infrastructure to create a physically separate network for new IP applications. This removes the tremendous capital investment needed to rip-and-replace the existing and proven infrastructure. Additionally, this prevents the need to layer voice onto the core data network; simplifying LAN management for IT teams.

The NVT Phybridge CHARIoT series of long reach Power over Ethernet (PoE) switches enable Modern LAN design; allowing any organization to transform their existing network infrastructure into a robust IP backbone for any hosted solution. The resulting network is physically separate and point-to-point; creating robust and cyber-secure pathways for each device. These smart pathways ensure optimal performance and reliability for any Cloud-based solution.

Replicate the Success

If you’ve had a conversation with someone at NVT Phybridge, you may have noticed that we speak a little differently. We speak differently because we are different. We’re swimming upstream when all other fish are swimming downstream. We’re driving towards the storm when everyone else is driving away from the storm.

We are different because we are innovators. We think differently, act differently, and speak differently in an effort to deliver on the founding promise of our organization; to bring only the most innovative solutions to market that are practical for both partners and customers. To be different we must also be bold. We must challenge deep-rooted industry paradigms to prove that IP modernization doesn’t need to be complex, cost-prohibitive and risky.

Digital transformation and the Internet of Things (IoT) has become a necessity for businesses that wish to remain competitive. However, as organizations become more intelligent and connected, their networks become more complex and less secure.

To solve this problem, we are fundamentally changing the conversation around traditional LAN design philosophies to improve the outcome for our partners and customers. This single purpose will drive every decision we make, from the products we develop, to the partnerships we engage in, to the impact we have on our communities, and especially – to the way we communicate.

IP migration is a term used in our industry to describe the process of moving from an older technology to an IP-based technology. For example, upgrading from an analog communication system to an IP voice solution. However, these organizations are not really “moving” from one technology to another, as the term “IP migration” would suggest. Organizations are “modernizing” their businesses with new technologies and innovations that allow them to do more than ever before.

Therefore, aligned with our commitment to change the conversation, we must also change the way we communicate. We use the term “IP modernization” where the industry would use the term “IP migration” because we don’t’ help our customers move from one technology to another. We help our customers modernize to the next generation of intelligent devices; giving them the tools they need to succeed – today and into the future.

Rethinking Network Design with Modern LAN Principles

We are not the only organization to recognize the need for innovation in an industry that sells innovations. In 2018, industry analysts from Frost & Sullivan recognized this gap and consulted NVT Phybridge as innovators in this space as they developed their revolutionary whitepaper titled, The Modern LAN: Rethinking Network Design for the Modern Age. As the title suggests, the whitepaper addresses critical issues with current LAN design philosophies as organizations continue to add more and more devices onto the network; including cybersecurity, reliability, performance, ROI and environmental impact. Our PoLRE® switch was featured in the whitepaper as a successful application of Modern LAN Principles. The Modern LAN whitepaper is another justification of our corporate mission to help organizations change the conversation to improve the outcome of their digital transformation.

Not every company has the opportunity to affect real change, but we do. Since our first product launch in 2008, we have had the pleasure of helping thousands of organizations around the world simplify their digital transformation. And still, so much potential lies ahead of us as we work to enable the future of connected devices.

Today, our CHARIoT series of long reach Power over Ethernet (LRPoE) switches and adaptors enable Modern LAN Principles; helping organizations simplify their upgrade to the latest IP solution with the freedom to leverage any new or existing infrastructure. This is made possible thanks to our SmartPathPoE technology.

What is SmartPathPoE Technology?

Devices are becoming more intelligent, requiring reliable power and data to distances farther than traditional Power over Ethernet (PoE) switches can provide. SmartPathPoE technology was developed to ensure your network is as intelligent as the devices it supports.

How Does SmartPathPoE Technology Improve your Outcome?

Don’t compromise on cost, security, reliability or performance. SmartPathPoE technology ensures your network is optimized to support each and every intelligent device.

SmartPathPoE Technology is Smart

Establish a simple and robust network topology with physically separate and cyber-secure point-to-point connections from endpoint to application; ensuring optimal reliability and performance from each device.

SmartPathPoE Technology is Simple

Leverage any new or existing infrastructure to simplify and accelerate your digital transformation. Our extensive portfolio of managed, unmanaged and single-port extender solutions ensures the perfect solution to meet your unique requirements.

SmartPathPoE Technology is Fast

Support IP endpoints with up to 6,000ft (1,830m) reach while delivering up to 100 Mbps symmetrical (full-duplex) – that’s 18 times farther than standard Power over Ethernet switches.

SmartPathPoE Technology is Environmentally Responsible

Eliminate the need to rip-and-replace existing network infrastructure and reduce your environmental footprint by preventing multiple tons of hardware and cabling e-waste.

SmartPathPoE Technology is Cost-Effective

Simple and fast implementation means you get access to your smart tools faster. Improve return on investment by reallocating infrastructure cost savings to more ROI-driving IP endpoints and applications.

CHARIoT Series of Long Reach Power over Ethernet Switches

SmartPathPoE Technology continues to separate the CHARIoT series from other solutions on the market. The CHARIoT series is comprised of three distinct product families:

PoLRE (Power over Long Reach Ethernet) family enables IP endpoints over single-pair UTP (unshielded twisted pair) up to 1,200ft (365m) – 4 times farther than standard PoE switches.

CLEER (Coax-Leveraged Ethernet Extended Reach) family enables IP endpoints over coax up to 6,000ft (1,830m) – 18 times farther than standard PoE switches.

FLEX family enables IP endpoints over multi-pair UTP up to 2,000ft (610m) – 6 times farther than standard PoE switches.

Our greatest potential is ahead of us…

We look to the future with clear vision and a singular purpose; to help our customers change the conversation to improve their outcome. This commitment builds on the ideals that inspired our founders to start this company over 10 years ago and will continue to be the driving force behind every decision we make.

Organizations are modernizing to IP communication, surveillance and other IoT (Internet of Things) devices to increase efficiency, improve security and create a better customer experience. Business Insider predicts that by 2025 there will be more than 55 billion connected IoT devices, up from 9 billion in 2017. To support these 55 billion IoT devices, organizations must first establish a secure and reliable local area network.

For over 25 years, NVT Phybridge has been committed to helping organizations maximize the return on investment of their digital transformations. Our CHARIoT series of enterprise-grade managed, unmanaged and single port extender solutions were designed specifically to simplify Modern LAN requirements. Enabled with SmartPathPoE technology, our solutions significantly reduce the cost to establish a secure and reliable Power over Ethernet (PoE) backbone.

How exactly? By transforming an organization’s existing infrastructure into a power-packed IP platform, with reach capabilities up to 6,000ft (1,830m) – 12 times farther than standard PoE switches. No more “rip-and-replace” and no more reach limitations. The cost savings are substantial considering the immense cost to install new infrastructure:

  • Thousands of feet of wiring to connect all devices on the local area network
  • Equipment to support new server closets or upgrade existing closets; including servers, racks, cooling systems, backup power systems, fire prevention, and redundancy equipment
  • Labour costs to rip-and-replace the existing infrastructure and install the equipment mentioned above
  • Material costs to support the construction and renovation work required to install the new infrastructure
  • Loss of revenue caused by business disruption

By eliminating the above requirements, project deployment times are significantly accelerated, further improving return on investment. Reduce infrastructure costs and allocate more of your budget to ROI driving applications.

Organizations that leverage their existing infrastructure to establish a robust PoE backbone are also creating a more cyber-secure network. Establishing a network today that can minimize susceptibility to cyber-attacks may save your organization millions of dollars in the future.
