Abstract
The present invention is a system for the transmission of a plurality of analog video, analog audio, and discrete signals across a single fiber optic cable. The system includes a transmitter which first digitizes the analog video and audio signals and then converts a combination of the digital video, digital audio, and discrete signals into a single serial digital data stream. The system modulates this digital data stream into a corresponding lightwave signal and transmits the lightwave signal across the fiber optic cable. A receiver within the system demodulates the lightwave signal into a serial digital data stream, which is then converted into a parallel signal so that the receiver may restore the analog video, analog audio, and discrete signals from the parallel combination of signals.
