Power over ethernet electrical to optical interface converter
A portable, self-powered, interface converter for converting between Ethernet over twisted pair cables and Ethernet over optical fiber is described. In one implementation, the device may include a first interface to a power-over-Ethernet connection and a second interface to provide a connection to receive fiber optic cabling. A power-over-Ethernet (PoE) circuit may derive power from the PoE connection and output a corresponding power signal. A transcoder may perform physical layer conversion between Ethernet communications over twisted pair cabling connected to the first interface and Ethernet communications over the fiber optic cabling. The transcoder may be powered by the power signal output by the PoE circuit.
