Passive PoE Injector Splitter kit with 5.5 mm x 2.1 mm DC Connector
Passive Power-over-Ethernet (PoE) allows low cost of delivery of power over the network cable.  This scheme allows power to be carried on 10/100 networks over the spare, unused pairs of a CAT5, CAT5E, or CAT6 Ethernet network cable.  Depending on distance (see http://wifiqos.com/poe-calc.html ) the power source could be the power supply that came with the wireless access point, IP video surveillance camera, etc. This set contains a very cost effective injector and breakout or splitter component. The injector inserts the DC voltage at the source location into the 5.5mm x 2.1mm injector plug. The DC voltage is then carried over the spare pairs of the 10BASE-T or 100BASE-T network cable. The breakout or splitter extracts the DC voltage from the network cable onto the 5.5mm x 2.1mm splitter jack. Also available is a 1.35mm version WS-POE-IO-1.35 and the gigabit version WS-GPOE-1-WWM
