  • Patent number: 11996817
    Abstract: A system, a non-transitory computer readable media and a method for FIR filtering. The method may include obtaining a set of input samples; and concurrently applying a FIR filtering process on the set of input samples to provide a set of FIR filtered output samples. The latter may include calculating intermediate results that represent a first number of coefficient-input sample products, while calculating only some of the first number of coefficient-input sample products, wherein the calculating of the intermediate results is executed by using less than a first number of multipliers.

  • Patent number: 11817909
    Abstract: A method for phase correction, the method may include generating in parallel and by a set of phase error detectors, a set of phase error detection results (PEDRs) related to a set of blocks of digital samples, the digital samples are frequency corrected and represent optical signals conveyed over a coherent optical communication link; wherein the PEDs introduce PED noise that is indifferent to phase errors of the set of the blocks of digital samples; sending, in a sequential manner, the set of PEDRs, to a loop that comprises a loop filter; generating, by the loop, phase difference results, wherein each phase difference result is indicative of a phase difference between a certain PEDR of the PEDRs and a loop filtered PEDR generated by filtering a PEDR that precedes the certain PEDR; and processing, by a phase correction unit, the digital samples and the phase different results, to provide phase corrected digital samples.

  • Publication number: 20170054533
    Abstract: An optical modulator with a region with non-linear characteristics with optimized BER performance, which comprises circuitry for adjusting the spacing between power levels of optical signals at the output of the optical modulator by adjusting the bias point of the optical modulator to be closer to a nonlinear region of the modulator, such that modulating signals having lower power will be compressed by the nonlinear region more than modulating signals having higher power. During adjustment, larger spacing between higher power levels of optical signals is introduced at the output of the optical modulator and lower spacing between lower power levels of optical signals is introduced at the output of the optical modulator.
