Network Pair Splitter will create an instant network connection from your existing Category 5 cabling. It works by utilizing the two unused pair of wires commonly found in Category 5 cable-which is all that is needed to make a new network connection. Installs easily and only requires 2 Network Pair Splitters. One plugs in at the patch panel and the other at the wall plate-that's it! In a situation where you need another network connection but pulling in more wire is cost prohibitive, this little wonder can save you time and tons of money.
