HDMI matrix switcher receiving side and receiver-side fiber connector power management

An HDMI (High Definition Multimedia Interface) fiber optic signal transmission cable, comprising:

• a cable including a plurality of optical fibers;
• a first connector connected to a first end of the cable, the first connector including:
• a first optical transceiver optically coupled to first ends of the optical fibers of the cable;
• a first control circuit electrically coupled to the first optical transceiver, configured to perform control and signal processing functions;
• a first HDMI interface having a first plurality of pins electrically coupled to the first control circuit;
• and
• a first power supply circuit coupled to a first designated pin of the first plurality of pins, configured to receive a first DC (direct current) voltage from the first designated pin and supply power to the first optical transceiver and the first control circuit;
• and
• a second connector connected to a second end of the cable, the second connector including:
• a second optical transceiver optically coupled to second ends of the optical fibers of the cable;
• a second control circuit electrically coupled to the second optical transceiver, configured to perform control and signal processing functions;
• a second HDMI interface having a first plurality of pins electrically coupled to the second control circuit;
• and
• a second power supply circuit coupled to a single second designated pin of the second plurality of pins, configured to receive a second DC voltage from the single second designated pin and supply power to the second optical transceiver and the second control circuit.
