A media converter for conversion between electrical signals and fiber optical signals includes an optical signal receiver circuit with a converter to change the optical signal into an analog electrical signal, a quantizer for converting the analog electrical signal into digital format, and an encoder for converting the signals from the quantizer into coding for wire transmission. A transformer isolates the receiver circuit from the media interface which is coupled to wire and optical cables. An optical signal transmission circuit includes a receiver for receiving the signals from metallic cable, a transformer for isolation of the transmission circuit, a decoder for converting the wire cable signals into a format for operation of an LED driver, an LED driver, an LED for producing digital light pulses, and an optical fiber interface for receiving the light pulses. The wavelength is preferably about 850 nanometers, but may also be about 1300 nanometers.
