Protecting Outdoor Installations: Understanding Surge Protection for Network Equipment


Transient Voltage Surges (TVS) pose a significant threat to outdoor network installations, particularly due to the risk of lightning strikes, both direct and indirect. These surges can damage network equipment, resulting in costly repairs and downtime. In this article, we’ll explore the importance of surge protection for outdoor installations and discuss key considerations for selecting and implementing Surge Protection Device (SPD) solutions.

Understanding the Importance of Surge Protection

Transient voltage surges, often caused by lightning strikes, power grid fluctuations, or electrical faults, can wreak havoc on network infrastructure, leading to equipment damage, downtime, and costly repairs. These surges are more prevalent when equipment is installed outdoors. Surge Protection Devices serve as the first line of defense against these electrical disturbances, diverting excess voltage away from sensitive equipment and ensuring uninterrupted operation in the face of adverse conditions.

Lightning strikes pose a threat to outdoor and indoor mounted equipment including long reach network infrastructure, by generating high-voltage surges that can propagate through cabling and damage or destroy connected devices. Surge Protection Devices mitigate the risk of damage by diverting lightning-induced currents to ground, protecting network equipment from catastrophic failure.

Power grid fluctuations, including voltage spikes and sags, can also compromise the integrity of outdoor network installations, leading to equipment malfunction or failure. Surge Protection Devices provide voltage regulation and transient suppression capabilities, stabilizing incoming power and safeguarding sensitive equipment from damage.

Leveraging Surge Protection Solutions

When selecting Surge Protection Device solutions, several key considerations must be considered:

  • POE Compatibility: It’s essential to ensure that Surge Protection Devices are compatible with Power over Ethernet (PoE) systems. Select devices with appropriate wattage and clamping voltage to prevent unintended activation and ensure the functionality of the equipment.
  • Impedance Matching: Match the impedance of the cable as closely as possible to optimize the performance of Surge Protection Devices and mitigate the risk of signal degradation.
  • Environmental Design: Choose Surge Protection Devices rated for the outdoor environment to withstand harsh weather conditions and ensure long-term reliability. Indoor-rated devices may not offer adequate protection against outdoor elements.

Research Collaboration with Surge Protection Manufacturers

NVT Phybridge has conducted thorough testing and research collaboration with Surge Protection Device manufacturers, including Ditek, to ensure compatibility with our technology. This collaboration has resulted in the identification of surge protection solutions that meet the stringent performance requirements of outdoor and extended reach network installations.
