Fiber Optic Return Transmitters For CATV (1992)

By Nigel Watson, Magnavox CATV Systems

This paper discusses the use of fiber optic transmitters utilizing Fabret-Perot (FP) lasers for return links in CATV distribution networks. The dynamic range achievable with a link driven by this type of transmitter is dependant on many factors which limit the achievable performance. Knowledge of their effects is important for optimizing the return link. Performance of prototypes operating over a 22 kilometer (7.5 dB) fiber link are reviewed and some of the design details for achieving the performance are explained.
