COTDR ARRANGEMENT WITH SWEPT FREQUENCY PULSE GENERATOR FOR AN OPTICAL TRANSMISSION SYSTEM

摘要

A method and apparatus is provided for obtaining status information from a given location along an optical transmission path (306, 308). The method begin by generating a cw probe signal having a prescribed frequency that is swept over a prescribed frequency range. The cw probe signal is transmitted over the optical path (306, 308) and a returned COTDR signal in which status information concerning the optical path is embodied is received over the optical path.
