Ubiquiti ETH-SP-G2 Ethernet Surge Protector - Gen 2
The Ubiquiti ETH-SP-G2 Ethernet Surge Protector is a cost-effective solution for protecting outdoor Ethernet devices against damaging electrostatic discharge and electrical surges. Designed for high-speed outdoor networks, the ETH-SP-G2 provides an additional layer of protection for Ubiquiti airMAX installations, which already include built-in ESD protection.
The ETH-SP-G2 is engineered to protect both Power-over-Ethernet (PoE) and non-PoE network devices operating at speeds of up to 1 Gbps. With two passive surge-protected RJ45 connections, it offers broad compatibility and can be installed between outdoor network equipment and the connected Ethernet network.
The Ubiquiti ETH-SP-G2 provides practical surge and ESD protection for outdoor Ethernet equipment without adding unnecessary complexity to the network installation. Surge events and electrostatic discharge are redirected through the protector and safely discharged to ground, helping reduce the risk of damage to connected network devices.
Its passive design supports straightforward installation, while the two RJ45 ports make it suitable for a wide range of Ethernet and PoE equipment. The ETH-SP-G2 is particularly useful for outdoor wireless networks, access points, Ethernet-connected devices and Ubiquiti airMAX deployments where additional protection is required.
Outdoor Ethernet Surge Protection
Outdoor network equipment can be exposed to electrical surges and electrostatic discharge, particularly when Ethernet cabling is installed between buildings or in exposed locations. The ETH-SP-G2 provides an additional protective layer by diverting damaging electrical energy away from connected network hardware.
The protector works alongside the built-in ESD protection found in Ubiquiti airMAX devices, providing an extra level of protection for outdoor high-speed network installations.
Protection for PoE and Non-PoE Networks
The Ubiquiti ETH-SP-G2 supports both PoE and non-PoE Ethernet equipment with connection speeds of up to 1 Gbps. This makes it suitable for installations where network connectivity and power may be delivered through Ethernet cabling.
Key technical points include:
Simple Installation for Network Protection
The ETH-SP-G2 is designed for a plug-and-play installation approach. Connect the Ethernet cables between the network devices and connect the protector to a suitable ground point. Once installed correctly, the device provides surge protection without requiring complex configuration or network management.
This straightforward installation makes the ETH-SP-G2 a practical addition to outdoor wireless links, access points and other Ethernet-connected equipment.
Ubiquiti ETH-SP-G2 for Outdoor Networks
For Ubiquiti airMAX deployments and other outdoor Ethernet installations, adding a dedicated surge protector can help provide additional protection against electrical events. The ETH-SP-G2 works with existing network equipment while maintaining support for high-speed Ethernet connections.
The model is identified by part number / SKU UB-ETH-SP-GEN2, making it easy to specify and source for compatible network installations.
Technical Details
Suitable Applications
The Ubiquiti ETH-SP-G2 is well suited to outdoor wireless networking, point-to-point links, access points, Ethernet-connected outdoor devices and Ubiquiti airMAX installations. It is a useful addition where Ethernet equipment may be exposed to electrical surges or electrostatic discharge and additional network protection is required.
