Regeneriertes optisches WDM Übertragungssystem

摘要

The transmission system has an optical transmitter and receiver connected by an optical fibre optics line. There are a number of optical regenerators (10) along the path. Each regenerator processes a different one of the channel groups, using a duplexer (12) to separate and amplify one of the channel signals and a second duplexer to recombine the channel signals with the others.
