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.

Claim (Index 21):
A frequency-division multiplexed system comprising:\n a transmission portion comprising:\n carrier signal emitters that produce carrier signals at different frequencies and that are phase or frequency correlated with each other; \n transmitters, each transmitter being connected to a corresponding one of the carrier emitters to receive a corresponding carrier signal therefrom, and each transmitter modulating the received carrier signal with transmission data to form a modulated carrier signal; and \n a frequency-division multiplexer connected to the transmitters to receive the modulated carrier signals and that combines the modulated carrier signals for transmission through a transmission link; and \n a reception portion comprising:\n a frequency-division de-multiplexer that receives the modulated carrier signals from the transmission link and separates them into individual modulated carrier signals; \n oscillators that produce oscillating signals at different frequencies and that are phase or frequency correlated with each other, each oscillating signal having a frequency that matches a frequency of a corresponding one of the carrier signals; \n receivers, each receiver being connected to the frequency-division de-multiplexer to receive one of the modulated carrier signals and being connected to a corresponding one of the oscillators to receive a corresponding oscillating signal therefrom, each receiver being connected to at least one other receiver to share process information, and each receiver that receives the process information using \n the received modulated carrier signal, \n the received oscillating signal, and \n the received process information to retrieve at least a portion of the transmission data.
