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