Abstract
A system for optical data interconnect of a source and a sink includes a first HDMI compatible electrical connector able to receive electrical signals from the source. A first signal converter is connected to the first HDMI compatible electrical connector and includes electronics for conversion of differential (including but not limited to TMDS and FRL) electrical signals to optical signals, with the electronics including an optical conversion device. At least one optical fiber is connected to the first signal converter. A second signal converter is connected to the at least one optical fiber and includes electronics for conversion of optical signals to HDMI standard TMDS or FRL electrical signals. A power module for the second signal converter includes a power tap connected to HDMI standard TMDS or FRL circuitry and a voltage regulator connected to the power tap to provide power to an electrical signal amplifier. A second HDMI compatible electrical connector is connected to the second signal converter and able to send signals to the sink.
