摘要： This disclosure describes techniques to utilize pluggable photonics module in high data rates optical communications systems such as some coherent optical communications system. The pluggable photonics module plugs into a host board. The host board includes a processor that compensates for distortion caused by data streams traveling across the pluggable interfaces that the pluggable photonics module and host board use to couple to one another.

摘要： This disclosure describes techniques to sample electrical data streams in coherent receivers. For instance, an analog-to-digital converter (ADC) samples the received electrical data stream at a sampling rate that is nominally twice or greater than twice the symbol rate of the electrical data stream that the ADC receives. A digital filter receives the digital data stream from the ADC, and digitally filters the digital data streams to output a filtered digital electrical data stream at an effective sampling rate that is less than the sampling rate and less than twice the symbol rate, and greater than or equal to the symbol rate.

摘要： Apparatus and techniques for receiving and processing an optical signal. In one implementation, an optical receiver is provided to include a delay line interferometer, an etalon, and a data estimator for estimating the data carried on a differentially modulated optical input signal. The delay line interferometer receives the input signal and issues differentially decoded constructive and destructive signals. The etalon filters the constructive signal with a transmission stopband imposed over the passband of the constructive signal. The bandwidth of the etalon stopband is selected based on the bandwidth of the modulation of the input signal in order to maximize received signal quality. The data estimator uses a difference between signals derived from the filtered constructive signal and the destructive signal for estimating data.

摘要： Apparatus and methods for optimizing the interplay between the sampling rate of an ADC of a receiver system and a bandwidth of analog anti-aliasing filters are described. The described technology can be used to mitigate aliasing for receiver systems that operate at fractional sampling rates by optimizing a bandwidth of optical and electrical filters included in the receiver systems.
