    摘要： Methods and devices for compensating for chromatic dispersion are shown that include receiving an input data signal, applying a filter to the data signal, and outputting a CD compensated signal. Applying the filter includes convolving known filter coefficients with a plurality of delayed versions of the data signal using addition and at least one inverse sign operation or using lookup tables and combining outputs to produce a CD compensated signal.

    摘要： An optical receiver system is disclosed. The system includes a local oscillator, a mixer and a processor. The local oscillator is configured to generate a laser signal to indicate a selection of one of a plurality of channels. In addition, the mixer is configured to receive signals on the plurality of channels and to utilize the laser signal to distinguish the signal on the selected channel. Further, the processor is configured to maximize a power level difference between the laser signal and at least one of the plurality of channels based on a total number of the plurality of channels by adjusting the power of the laser signal input to the mixer to limit a noise penalty in the receiver system.

    摘要： A wavelength division multiplex transmitter is provided, which is capable of automatically setting up the number of wavelengths and detecting a trouble in a transmission path, and so making a WDM transmission with always keeping the whole of the system at the optimum level. In a WDM system, light detection monitors are provided in the light signal input part of an AWG module, and the number of wavelengths to be multiplexed is determined based on the light input powers.
