摘要： A method of measuring the error rate of an optical transmission system transmitting a signal by detecting the signal, and asynchronously sampling the signal at a frequency independent of the bit rate of the signal to obtain K samples of the signal at respective times t1 to tK, where K is an integer greater than or equal to 2. The eye diagram of the signal, the error rate of the signal and the bit time of the signal are then computed.

摘要： The invention concerns a system for compensating polarization dispersion of channels in a wavelength-division multiplex signal. In accordance with the invention, the system comprises a plurality of cascaded polarization control modules respectively associated with said channels and a common differential delay generator. Each polarization control module comprises a drop and insert multiplexer for extracting the signal from the associated channel from the input multiplex signal and inserting a modified channel supplied by a polarization controller. The system further comprises a control loop for controlling the polarization controllers in response to the optical properties of the channel signals at the output of the differential delay generator and obtaining a compensated multiplex signal.

摘要： To increase the transmission length in an optical fiber, a method of transmitting digital data uses both power modulation and phase modulation of an optical carrier. To compensate the chromatic dispersion produced by the fiber, a phase-shift is applied to the wave within each time cell in which the optical power is low and that precedes or follows a cell in which the power is high. Applications include long-distance optical transmission using standard fibers.
