Because fiber optics has quickly become an accepted technology in AM, CATV applications, the understanding of many component specifications and their impact on system performance has lagged behind. This paper examines current fiber optic cable specifications, and how cable made to these specifications can affect the performance of AM, fiber optic, CATV systems in the field.
It is shown that many of the currently applied telephony specifications are suitable for CATV applications. But, some specifications, in particular temperature performance, should be re-examined in order to meet the needs of the CATV AM video market place.
