Protección contra sobretensiones Cambium Networks SURGE SUPPRESSOR — protección externa contra rayos y sobretensiones para dispositivos de red

Cambium Networks SURGE SUPPRESSOR is an external surge protection device designed to safeguard network equipment from lightning strikes and transient voltage surges. Intended for outdoor installation on network links and antenna feed lines, the unit provides a single, dedicated protection point to reduce the risk of damage to radios, converters and switches. The device is suitable for deployment where PoE-powered devices and rooftop antennas are exposed to electrical transients caused by storms or nearby lightning activity.

Advantages

The surge suppressor offers a compact, weather-resistant form factor for outdoor use and integrates with standard coaxial and Ethernet feed lines without requiring changes to connected equipment. It limits voltage spikes and diverts transient energy away from sensitive electronics, helping to preserve service continuity and reduce repair and replacement costs. Installation at the network edge or antenna feed minimizes the propagation of surges into downstream devices.

Suitable for

• Protection of outdoor wireless radio links and backhaul connections
• Shielding rooftop antennas and feed lines from transient overvoltage
• Protecting PoE-fed access points, cameras and switches in outdoor deployments

Key specifications

• External device designed for outdoor installation on antenna and network feed lines
• Provides transient voltage suppression for connected network equipment
• Compatible with common outdoor radio and PoE network configurations
• Weather-resistant construction for exposure to environmental conditions

How to use

Install the surge suppressor inline on the antenna feed or network cable between the outdoor device and the indoor equipment or grounding point. Ensure proper grounding according to site electrical standards so diverted surge energy has a low-resistance path to earth. Position the unit as close as practical to the point of entry or the antenna to limit surge energy reaching the protected device. Verify connections are tight and weatherproofed where cable assemblies pass through enclosures.

Recommendations

Use the surge suppressor as part of a layered protection strategy that includes proper grounding, cable routing, and, where applicable, additional surge protection at distribution panels. Periodically inspect the device and grounding connections after severe weather events and follow manufacturer guidance for maintenance and replacement intervals.
