Abstract
In an improved wavelength-division multiplexed system, transmitters modulate carrier signals that are phase or frequency correlated with each other. Receivers retrieve transmission data from the modulated carrier signals by demodulating and equalizing the modulated carrier signals using oscillating signals that are also phase or frequency correlated with each other. Each oscillating signal has a wavelength that matches a wavelength of a corresponding one of the carrier signals. At least one of the receivers generates process information during the demodulating and equalizing. The process information is sent to at least one other receiver, which uses the process information to retrieve at least a portion of the transmission data.
