Wavelength path monitoring/correcting apparatus in transparent optical cross-connect and method thereof

摘要

A wavelength path monitoring/correcting apparatus used in a transparent OXC is disclosed. The apparatus includes: a path information generating section for generating a path monitoring information; a plurality of optical couplers for coupling each output signal of the wavelength division demultiplexers with the pertinent path monitoring information; a plurality of optical switches for switching each optical signal inputted from the optical couplers; a plurality of wavelength division multiplexers for multiplexing optical signals inputted through the optical switches; a path information detecting section for detecting the path monitoring information from optical signals outputted from the wavelength division multiplexers; and, a path control section for comparing the path monitoring information detected through the path information detecting section with a predetermined optical switching information and for correcting switched paths.
