Ubiquiti Ethernet Surge Protector Gen2



ESD protection for outdoor high-speed networks.

Introducing the next generation Ethernet Surge Protector, model ETH-SP-G2, from Ubiquiti. The ETH-SP-G2 is a cost-effective solution for protecting outdoor Ethernet devices from damaging electrostatic discharge and surges. Since all Ubiquiti® airMAX devices already have robust ESD protection built in, adding the ETH-SP-G2 to the installation provides an additional layer of protection to the network.

The ETH-SP-G2 is engineered to protect Power-over-Ethernet (PoE) or non-PoE devices with connection speeds of up to 1 Gbps. Two passive, surge-protected RJ45 connections provide maximum equipment compatibility.
