This 2-port passive splitter is handy when you need another network connection but don"t have the time or the money to add another cable drop. Simply plug one device into your work area network port and another unit to the corresponding patch panel port. Now you can run two network devices over the same network cable. Non-intrusive to the network; a simple plug-and-play installation. Please Note: Sold individually, this item must be used in pairs for each installation, one on each end of the cable.
