Circuit arrangement for dispersion compensation in optical multiplex - transmission systems with the aid of dispersion-compensating fibers

摘要

The circuit arrangement utilises dispersion compensated optical fibre to provide compensation for dispersion in a multiplexed optical transmission system. An individual fine compensation of a corresponding residual dispersion is provided in addition to the coarse compensation for every channel. One or more dispersion-compensated fibres (DCF) are inserted into the transmission line (UF) of a WDM system, to provide the fine compensation.
