Patent ID: 8521032

Claim:
A media converter to convert between digital fiber optic signals and electronic signals comprising: a differential transmit stub, a transmit stub interface and an optical fiber transmit interface in serial flow communication in a first communication path; and a differential receive stub, a receive stub interface and an optical fiber receive interface in serial flow communication in a second communication path; the first communication path and second communication path transmitting signals in opposite directions between an electronic component and an optical fiber coupler; the first communication path configured to convert an electronic signal received from the electronic component to a digital optical signal for transmission to the optical fiber coupler; and the second communication path configured to convert a digital optical signal received from the optical fiber coupler to an electronic signal for transmission to the electronic component; wherein: the media converter further includes a diode bridge, a voltage regulator and a transmit inhibit diode; the diode bridge is configured to convert AC electrical power from the electronic signal power received from the differential transmit stub and the differential receive stub, and provide DC power to the voltage regulator; and the voltage regulator is configured to control the optical fiber transmit interface through the transmit inhibit diode and to provide DC voltage at a plurality of DC voltage levels.
