Available features

  • Several digital modulations available (M-PAM, square M-QAM, M-PSK, OOK) to simulate IM-DD and coherent optical systems.

  • Numerical models to simulate optical transmitters, optical amplification, nonlinear propagation over optical fibers, and optical receivers.

  • CPU and GPU-based implementations of the split-step Fourier Method <https://en.wikipedia.org/wiki/Split-step_method>__ to simulate polarization multiplexed WDM transmission.

  • Standard digital signal processing (DSP) blocks employed in coherent optical receivers, such as:

    • Signal resampling.
    • Matched filtering.
    • Clock recovery.
    • Electronic chromatic dispersion compensation (EDC).
    • Several NxN MIMO adaptive equalization algorithms.
    • Carrier phase recovery algorithms.
  • For most of the cases, Numba <https://numba.pydata.org/>__ is used to speed up the core DSP functions.

  • Evaluate transmission performance with metrics such as:

    • Bit-error-rate (BER).
    • Symbol-error-rate (SER).
    • Error vector magnitude (EVM).
    • Mutual information (MI).
    • Generalized mutual information (GMI).
    • Normalized generalized mutual information (NGMI).
  • Visualization of the spectrum of electrical/optical signals, signal constellations, and eyediagrams.
