SP-POE-01 is an in-line RJ45 Ethernet Cat6 cable surge protector. It installs simply on a Cat5, Cat 5e or Cat6 4 twisted pair cable. Features: Device is using special diodes and gas discharge modules for effective lightning protection. It protects any RJ45 Ethernet based device like switches, DSL modems, routers, computers, etc. The Ethernet surge protector is also available in special multi-port version with 8, 16 or 24 surge protecting ports. The 8 pin surge protector is also good for RJ48c 100ohm T1 interfaces, providing effective surge protection on all 8 pin connectors from the T1 copper interface. Fast energy absorption on over-voltage Low resistance and minimal capacitance - minimal influence on data link Easy in-line installation: two RJ45 female connectors Note: This special surge protector version does SUPPORT the IEEE 802.3af PoE standard (Power over Ethernet).You can use such protector on PoE active cabling. The compatibility is assured with the IEEE 802.3af standard by supporting a much higher clamping voltage of 53V. Technical specifications Discharge current max.: 5KA Discharge current nominal: 0.5KA Max. voltage: 6.8V Data (pins 1,2,3 and 6) and 53V PoE (pins 4,5,7 and 8) Response time: line-line
