摘要： Methods, systems, and devices are described for modulating and demodulating data on optical signals. During modulation, at least one stream of symbol mapped bits is filtered with at least one pulse shaping filter to reduce a bandwidth of the stream of bits and to pre-compensate for at least one identified non-ideal transmission condition. The filtered bits are modulated onto a waveform in the digital domain, and the modulated filtered bits are transmitted to digital-to-analog converter. The output of the digital-to-analog converter is converted to an optical signal. During demodulation, a received optical signal is sampled at a first sampling rate at an ADC, downsampled to a lower sampling rate for filtering, filtered with at least one discrete pulse-shaping filter, upsampled for equalization and demodulation, and then equalized and demodulated.

摘要： A polarization demultiplexing optical communication receiver is provided with a signal quality change imparting means which imparts a signal quality change to multiplexed two optical signals; and a signal quality monitoring means which compares signal qualities of the two optical signals with each other after the multiplexed two optical signals imparted with the signal quality change are subjected to polarization separation so as to specify the two optical signals based on a result of the comparison. This makes it possible to reduce transmission characteristics degradation of a polarization-multiplexed optical signal, and to implement transmission having high reliability.
