A transmitting device includes a housing, a multichannel transmitter optical subassembly, a microcontroller, and a DVI connector. The housing has only one optical port, where the only one optical port is adapted to receive only one optical fiber. The multichannel transmitter optical subassembly is mechanically associated with the housing. The microcontroller is electrically associated with the multichannel transmitter optical subassembly. The DVI connector is mechanically associated with the housing. The transmitting device is adapted to convert at least four electrical TMDS signals into optical paths that are transmittable over the only one optical fiber. A receiving device is similar to the transmitting device, however, in contrast to the transmitting device, the receiving device includes a multichannel receiver optical subassembly, and wherein the receiving device is adapted to convert multiple colored wavelengths into at least four electrical TMDS signals.
