A system and method for optically testing broadcasting systems

摘要

The present invention is a system and method for optically testing secondary fiber paths from a splitter to local customer areas. The optical splitter splits the CATV signal and transmits it to various local customer areas. A network communications signal such as a smart local access network (SLAN) signal and a test signal such as an optical time domain reflectometer (OTDR) signal are transmitted to an optical switch having various output paths. The SLAN signal controls the OTDR test signal and the switch switches the transmission of the test signal along the output paths to the secondary fiber paths to test the integrity of the secondary fiber paths.
