The Ethernet Surge Protector is a cost-effective solution for protecting sensitive, 3rd party Ethernet devices from damaging electrostatic discharges and surges. Since all Ubiquiti airMAX® devices already have robust ESD protection built in, adding the ETH-SP to the installation provides an additional layer of protection to the network. 

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

• Compatible with Gigabit Networks
