A media converter for interfacing an optical fiber bus to an electrical interface of an electronic device is described. The media converter includes an interface circuit configured to convert electrical signals received from a transmitting channel of the electrical device in a voltage doublet format to positive logic electrical pulses and convert received electrical signals for application to a receiving channel of the electrical device from positive logic electrical pulses to a voltage doublet format, a DC coupled receiver comprising an optical interface operable for receiving optical signals from the optical fiber data bus, the receiver operable for converting the optical signals to positive logic electrical pulses for application to the interface circuit, a laser diode operable to transmit optical signals onto the optical bus, and a laser diode driver operable for receiving the positive logic electrical pulses from the interface circuit and converting the electrical signals to signals compatible for operating the laser diode.
