摘要： A WDM system having at least two channels, each of which employs two polarizations, is arranged so that the start times of symbols carried by one polarization of a channel are displaced in time from the start times of symbols carried by the other polarization of that channel, e.g., the start time for each symbol on one polarization is not substantially synchronized with the closest-in-time symbol start time on the other polarization of that channel. Preferably, the data signals are modulated using a return-to-zero (RZ) format and the start times of the symbols of the data signal carried by one polarization of a channel is offset from the start time of the symbols data signal carried by the other polarization of that channel by between 20% to 80%—preferably 50%—of the symbol period of the data signals, when the data signals have the same symbol period.

摘要： An optical transport system in which (i) an optical transmitter is configured to adaptively change an operative constellation to use a constellation that provides optimal performance characteristics for the present optical-link conditions and/or (ii) an optical receiver is configured to change shapes of the decision regions corresponding to an operative constellation to adapt them to the type of signal distortions experienced by a transmitted optical signal in the optical link between the transmitter and receiver. Under some optical-link conditions, the optical receiver might use a decision-region configuration in which a decision region corresponding to a first constellation point includes an area that is closer in distance to a different second constellation point than to the first constellation point.

摘要： An apparatus, e.g. an optical data transmission device, is configured to propagate a non-return-to-zero (NRZ) modulated optical communication signal. A plurality of optical amplifiers are configured to receive the modulated optical signal. An optical transmission line includes a sequence of at least five spans of optical fiber, with each adjacent pair of the spans being connected by one of the optical amplifiers. Between about 10% and about 75% of the optical amplifiers include a dispersion compensation module (DCM) and a remainder of the optical amplifiers do not include a DCM, and at least two of said optical amplifiers are optically coupled between a first and a second optical add-drop multiplexer.

摘要： A method and system for suppressing signal distortions in optical signals associated with nonlinearity in optical fibers includes propagating an optical signal through a transmission medium, the transmission medium comprising a sufficiently low dispersion such that a nonlinear distortion imparted on the propagating optical signal by the transmission medium is imprinted primarily on an optical field phase of the optical signal, and converting the propagated optical signal to an electrical signal such that the optical field phase information of the optical signal is not translated into the electrical domain.
