Abstract

A wideband fiber optic video distribution system with a bandwidth exceeding 20 MHz has been developed for the NASA Space Station Freedom. The system uses FM modulation and light emitting diodes in combination with lightweight and rugged fiber optic cables and digital switching elements to provide lightweight, reliable, high-performance video signal distribution over the full extent of the Space Station. The author addresses the Space Station requirements, including environmental constraints, which led to the selected system architecture and choice of components. The design of the modulators and demodulators, optical transmitters and receivers, fiber optic cable, and the video switches is discussed. Also presented is a description of how the technology can be applied to those military needs which would benefit from the performance, reliability, and EMI/TEMPEST features of the system
