&lt;b&gt;ESD Protection for Outdoor High-Speed Networks&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;Introducing the Ethernet Surge Protector model ETH-SP from Ubiquiti Networks. The ETH-SP 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 to the installation provides an additional layer of protection to the network.&lt;br /&gt;&lt;br /&gt;The ETH-SP is engineered to protect Power-over-Ethernet (PoE) or non-PoE devices with connection speeds of up to 1Gbps. Two passive surge-protected RJ45 connections provide maximum equipment&lt;br /&gt;compatibility.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Ideal for WISP Networks&lt;/b&gt;&lt;br /&gt;All Ubiquiti airMAX devices are equipped with ESD protection. However to protect outdoor devices and to meet certain local code requirements installing the ETH-SP is essential.&lt;br /&gt;&lt;br /&gt;For example to guard against costly service calls and to help your subscriber installations meet code requirements install two ETH-SPs: one near the CPE and the other at the entry point to the building.&lt;br /&gt;Damaging ESD attacks and surges will be absorbed by the ETH-SPs and safely&lt;br /&gt;discharged into the ground.
