Abstract
Abstract A self-powered fiber optic interconnect system in which electrical output from data transmitting equipment is converted in a transmitter unit to optical signals in a fiber optic cable for transmission to a receiver unit for reconversion to electrical signals for data receiving equipment and a power source separate from the transmitting and receiving equipment so that the interconnect system can be completely interchangeable with an electrical copper wire interconnect system. When the data transmitting equipment is a computer with parallel data output, the transmitter unit converts the parallel output to serial data output for transmission to the receiver unit over a single fiber optic cable and the receiver unit reconverts the output to parallel data for the data receiving equipment.
