What is Power over Ethernet (PoE)?
What is PoE?
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. PoE networks can source power at the network switch side or at a PoE injector to add power to an existing data line.
How Does PoE 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.
History of Power over Ethernet
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 in 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 CAT5 cables, and power was 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 PoE was 802.3AF, which states that compliant Power over Ethernet switches deliver 15.4W of power to guarantee delivery of 12.95W at the endpoint.
For more information, see our comprehensive breakdown of Power over Ethernet Standards, History, and Evolution.
What is PoE+?
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 PoE.
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 used |

There are varying names for these PoE 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 Classes
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 |

In most cases, the datasheet of a PD will display the PoE 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 PoE 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.
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
PoE 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 PoE switch fabric when modernizing from older, analog voice and security systems, or when deploying a new system. NVT Phybridge PoE switches provide numerous benefits:
- Lower infrastructure costs
- Fast and simple deployment
- Improved LAN design
- Less 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.

Managed vs. Unmanaged Switches Explained
Managed Versus Unmanaged Switches: What is the Difference Between Managed and Unmanaged Switches?
What is a network switch?
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.
There are two types of network switches: managed and unmanaged. It is important to understand the differences between managed and unmanaged switches when setting up a network.
What is an Unmanaged Switch?
An unmanaged 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.
What is a Managed Switch?
A managed 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. 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.
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 to 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.

El Paseo South Gate Deploys Axis IP Camera Solution Using NVT Phybridge PoE Innovations
NVT Phybridge Case Study: El Paseo Shopping Center
El Paseo South Gate Shopping Deploys Axis IP Cameras Using NVT Phybridge CLEER24 Long Reach Ethernet Over Coax Switch Solution
El Paseo South Gate is a large shopping center, located in South Gate, California. Guests visit to take advantage of the shopping, food, and entertainment amenities while enjoying the stunning modern architecture and large outdoor murals.
El Paseo South Gate was relying on an analog surveillance system that was installed in the late ‘90s. The system was becoming increasingly unreliable and could no longer meet the organization’s modern-day security needs. The center tried replacing the cameras and the DVRs, however, this did not provide the ideal level of quality that was needed. El Paseo South Gate wanted to modernize its surveillance capabilities and deploy a new IP security solution.
Problem
Several challenges needed to be addressed before implementing the new IP security system. El Paseo South Gate wanted to deploy IP cameras to get complete surveillance coverage throughout the interior of the mall and in outdoor areas, including parking lots and the parking garage. Many desired endpoint locations were well beyond the 328ft (100m) reach limitation of standard Ethernet switches, and installing IDF closets would add cost and complexity to the project.
A Coax-based infrastructure supported the existing analog camera system. The customer was concerned with the potential high cost, complexity, and disruption from ripping out the Coax and replacing it with a CAT6/Fiber backbone. Additionally, there was minimal cable route location information due to a lack of documentation from the original installation. Many environments, including the parking garage, had concrete walls, making the task of re-cabling even more difficult. The customer needed an innovative solution to overcome its IP modernization challenges.
Solution
OC Tech Innovations (OCTI) met with NVT Phybridge at ISC West, one of the largest North American security events, and discovered the CLEER24 long reach PoE switch. The enterprise-grade CLEER24 switch is an EoC (Ethernet over Coax) innovation that delivers Ethernet and PoE+ over any new or existing Coax cable with up to 6,000ft (1,830m) reach. That’s 18-times the reach of a standard Ethernet switch. OCTI connected with the local NVT Phybridge team and arranged a proof-of-concept to test the solution.
After a few simple setup steps, the CLEER24 transformed the customer’s existing and proven Coax-based infrastructure into a robust IP backbone for the new IP cameras. OCTI and NVT Phybridge worked together to deliver several pre-sale demonstrations for the customer to ensure it was the right solution for their needs. El Paseo South Gate was impressed with the solution and decided to move forward with the modernization initiative.
Result
Reduced infrastructure Costs for Better ROI
El Paseo South Gate was completely satisfied with the entire experience. OCTI used the CLEER24 switch to enable several of the IP cameras, including those in hard-to-reach places, such as the parking garage. “The CLEER24 switch was especially helpful when connecting IP cameras on the fifth level of the parking garage”, said Behzad Faridnia, Founder and Chief Innovator, OC Tech Innovations. “These runs were originally done via encased conduit without pull strings. If new cabling was needed, this would have required a new surface-mounted conduit system to be installed.” OCTI estimates that El Paseo South Gate saved approximately $465,000 in infrastructure costs using the NVT Phybridge CLEER24 switch; a total cost reduction of 71%. “We are confident that this would not have been possible without the NVT Phybridge EoC product line,” said Behzad. “The client is very satisfied as they were able to avoid costly trenching and unsightly conduit runs to install these new cameras.”
Simple and Fast Deployment
By leveraging the NVT Phybridge CLEER24 switch and avoiding the rip-and-replace process, the total deployment time was reduced by two months. “The NVT Phybridge solutions were easy to deploy,” said Behzad. “Their wide range of adapters allowed us to include multi-sensor and PTZ cameras (pan-tilt-zoom) with higher PoE requirements while auto-negotiating PoE within the same system from the same switch.”
The slim form factor of the CLEER24 switch was easily incorporated into the customer’s existing rack and ensured plenty of open rack space for future expansion. “The NVT Phybridge extenders are slim and fit easily into the pole mount and enclosures where space is at a premium”, said Behzad. “The NVT Phybridge extenders are far slimmer than the other brands on the market.”
Simple LAN Design
OCTI was able to consolidate all cable runs to the customer’s main server room without the need for costly intermediate distribution frame (IDF) closets. “This significantly reduced network costs for El Paseo South Gate and simplified network design as we were able to utilize all original conduit runs, removing the need for costly trenching”, Behzad commented.
Superior Performance at Greater Lengths
The NVT Phybridge EC4 adapter provides the ability to connect up to four IP devices over one long-run Coax cable. OCTI and El Paseo Plaza plan to add Axis IP-based annunciators using the existing Coax cable runs and the EC4 adapter.
When assessing the customers existing infrastructure, OCTI found that many cable runs had several splices with BNC couplers. “At first, we were concerned that these splices would degrade the overall signal,” said Behzad. “However, the signal had no issue passing through, even when with an 8-splice run.” The CLEER24 switch was able to support high-demand cameras at great lengths, even in the toughest environments. “Even when connecting the longest cable run, we had no issues getting the IP camera online,” commented Behzad.
Physical Network Segmentation
OCTI was able to maintain a physically separate network for the new Axis IP camera system. This will enhance network security, reduce ongoing costs, and simplify LAN management. “For security reasons, the system is “air-gapped” with the Video Management System (VMS) acting as the middleman between the surveillance network and the local LAN network for other devices”, said Behzad. “The NVT Phybridge admin portal was easy to configure for alignment with the surveillance-only subnet.”
Industry-Leading Pre and Post Sale Support
“Pre- and post-sales support were beyond the level we expected in terms of detail and personalization,” said Behzad. “This was a breath of fresh air as far too many companies disappear once the project is won. We appreciated the support and look forward to adding NVT Phybridge as our go-to solution for IP modernization projects. We are already exploring the use of other products for other challenges we are facing”.

BOOK A MEETINGGlobal Leader in Sports Broadcasting Avoids Business Disruption While Modernizing to Cisco IP Using NVT Phybridge PoE Technology
Sports Broadcasting Network Modernizes to Cisco IP Using NVT Phybridge PoLRE® PoE Switch
Problem
An American sports broadcasting network wanted to modernize to an IP communication solution without disrupting its 24/7 operations. The organization was relying on a digital phone system that was obsolete and becoming increasingly inefficient and costly. However, the existing phone system was supported by a single-pair UTP infrastructure that was not ready to support the new IP devices. While the customer wanted to modernize to Cisco IP, they were not interested in the risk, complexity, and business disruption that would result from ripping out the existing infrastructure and replacing it with new CAT5/6 Ethernet cabling.
Strict company policy mandated 24/7 operational uptime, which meant there was no allowance for the disruption that the re-cabling would cause. Additionally, the enormous cost associated with infrastructure requirements was not in the budget’s scope, creating additional barriers and challenges to deploying the new Cisco IP communication solution. The sports broadcasting network needed an innovative solution to overcome its infrastructure barriers and complete its digital transformation project.
Solution
The customer’s IT Director met with the NVT Phybridge team at an industry event and discovered the PoLRE® (Power over Long Reach Ethernet) switch. The enterprise-grade PoLRE switch delivers fast Ethernet and PoE over single-pair UTP cable with up to 1,200ft (365m) reach; that’s four times the reach of standard Ethernet switches. The IT Director was impressed with the technology and organized a proof of concept to test the solution in a live environment.
After a few simple setup steps, the PoLRE switch transformed the customer’s existing and proven single-pair UTP infrastructure into a robust PoE network to support the new Cisco IP communication solution. After experiencing the features and benefits of the PoLRE switch first-hand, the customer was confident that the technology would overcome the digital transformation barriers.
Result
The sports broadcasting network saved over $500,000 in infrastructure costs using the NVT Phybridge PoLRE switches. The customer significantly simplified and accelerated its digital transformation project, deploying the new Cisco IP communication solution without disrupting its regular business operations. The PoLRE switch’s extended reach capabilities simplified LAN design and ongoing network management, as the customer was able to support the new IP phones exactly where they were needed without additional IDF closets. “It’s a pretty straightforward process,” said Richard Smith, Product Sales Specialist, GSP America. “The big advantage for us was delivering outstanding service, which was critical for the success of the project”. The customer was able to avoid the traditional rip-and-replace upgrade method, using NVT Phybridge PoE Switches to improve the outcome of the digital transformation project.
PoLRE Innovation
The NVT Phybridge PoLRE switches deliver Ethernet and PoE over a single pair of telephony grade wire with four times the reach of traditional PoE switches. Transform any new or existing infrastructure into an IP path with power and achieve a simple, secure, and cost-effective modernization. The PoLRE switch is available in 48, 24, and 8-port managed and unmanaged models.

However, the existing phone system was supported by a single-pair UTP infrastructure that was not ready to support the new IP devices. While the customer wanted to modernize to IP, they were not interested in the risk, complexity, and business disruption that would result from ripping out the existing infrastructure and replacing it with new CAT5/6 Ethernet cabling.
Strict company policy mandated 24/7 operational uptime, which meant there was no allowance for the disruption that the re-cabling would cause. Additionally, the enormous cost associated with infrastructure requirements was not in the budget’s scope, creating additional barriers and challenges to deploying the new IP communication solution. The sports broadcasting network needed an innovative solution to overcome its infrastructure barriers and complete its digital transformation project.
Solution
The customer’s IT Director met with the NVT Phybridge team at an industry event and discovered the PoLRE® (Power over Long Reach Ethernet) switch. The enterprise-grade PoLRE switch delivers fast Ethernet and PoE over single-pair UTP cable with up to 1,200ft (365m) reach; that’s four times the reach of standard Ethernet switches. The IT Director was impressed with the technology and organized a proof of concept to test the solution in a live environment.
After a few simple setup steps, the PoLRE switch transformed the customer’s existing and proven single-pair UTP infrastructure into a robust Power over Ethernet network to support the new IP communication solution. After experiencing the features and benefits of the PoLRE switch first-hand, the customer was confident that the technology would overcome the digital transformation barriers.
Result
The sports broadcasting network saved over $500,000 in infrastructure costs using the NVT Phybridge PoLRE switches. The customer significantly simplified and accelerated its digital transformation project, deploying the new IP communication solution without disrupting its regular business operations. The PoLRE switch’s extended reach capabilities simplified LAN design and ongoing network management, as the customer was able to support the new IP phones exactly where they were needed without additional IDF closets. “It’s a pretty straightforward process,” said Richard Smith, Product Sales Specialist, GSP America. “The big advantage for us was delivering outstanding service, which was critical for the success of the project”. The customer was able to avoid the traditional and outdated rip-and-replace method, using Modern LAN principles to improve the outcome of the project significantly.

In the sixth and final episode of the Business of Technology Podcast Series, John Croce, CEO of NVT Phybridge, explores the idea of “scope creep” and whether it represents a threat or an opportunity. Croce reflects on the crash of Nortel, from a leader in networking and communications equipment to an extinct company. According to Croce, Nortel is gone, partly due to scope creep. Croce reflects that today, many large voice providers with an extensive legacy customer base are losing market share. Selling communication is more complex, with additional stakeholders and decision-makers to consider.
What can we do about scope creep? Gain end-to-end control and bring a more compelling voice offering. Croce offers recommendations and discusses how NVT Phybridge innovations create a modernization path to reduce network readiness costs while delivering better reliability and quality of service.

BOOK A MEETINGWhat is Power over Ethernet (PoE)? Everything you need to know!
What is Power over Ethernet (PoE)?
What is PoE?
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. PoE networks can source power at the network switch side or at a PoE injector to add power to an existing data line.
How Does PoE 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.
History of Power over Ethernet
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 in 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 CAT5 cables, and power was 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 PoE was 802.3AF, which states that compliant Power over Ethernet switches deliver 15.4W of power to guarantee delivery of 12.95W at the endpoint.
For more information, see our comprehensive breakdown of Power over Ethernet Standards, History, and Evolution.
What is PoE+?
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 PoE.
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.
Pins 3, 6 = Negative Voltage (DC-)
Pins 7, 8 = 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.
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:
Mode B
“PoE+”
“High PoE”
Mode B
“PoE++”
Mode B
4PPoE
“PoE++”
There are varying names for these PoE 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 Classes
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:
not allowed for 802.3af devices
In most cases, the datasheet of a PD will display the PoE 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 PoE 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.
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
PoE 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 PoE switch fabric when modernizing from older, analog voice and security systems, or when deploying a new system. NVT Phybridge PoE switches provide numerous benefits:
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.

Podcast: The Business of Technology Episode Five
What is Virtual LAN Segmentation, And How Does it Compare with Physical Segmentation?
As customers modernize from analog/digital to IP voice, whether in the Cloud or on-premise, voice is being layered on to a network not designed for voice. This can present a set of challenges, including QoS issues, poor performance and reliability, more complex network management, and voice and data teams at odds with one another. In this podcast, John Croce, CEO of NVT Phybridge, takes a look at these issues and then explores options. Croce quotes Albert Einstein, saying that “you cannot solve a problem using the same kind of thinking that was used to create it.” Croce challenges the notion that VLAN is the most effective strategy since VLANs are using the same thinking to solve a problem that created the problem. Physically separate networks may provide a better alternative. Croce outlines the NVT Phybridge approach that provides a more robust option with significant cost savings as organizations leverage existing infrastructure, compatible with major voice platforms, such as Cisco, Avaya, and Mitel.
