PERFORMANCE COMPENSATED TX/RX OPTICAL DEVICES

摘要

A wavelength division multiplexing system has a wavelength division multiplexer and a wavelength division demultiplexer. The wavelength division demultiplexer is in series with she wavelength division multiplexer to process at least one optica! signal to generate at least one processed optica! signal The wavelength division multiplexer and the wavelength division demultiplexer cooperate to introduce substantially zero total chromatic dispersion in the processed optica! signal, In one version, the wavelength division multiplexer and the vvavelength division demultiplexer introduce opposing functions of chromatic dispersion into into the at least one processed optical signal.
