Power over Ethernet, or PoE for short, is a feature that allows electrical power to be carried by network cables over an existing data connection. This means that network cables can pass electricity through them. For this to happen, a Cat5e or Cat6 ethernet cable is needed. The job of this cable is to connect two devices together for the local network, as well as for internet network and file sharing. The company Cisco is credited with pioneering the PoE movement, when in 2000 they came up with the first ever successful system. There are many reasons for PoE’s rise to prominence, with the expansion of technology obviously a major factor.
