Key Features
  • Built-in dispersion compensation, polarization de-multiplexing, and carrier recovery algorithms
  • Supports DP-QPSK, DP-16QAM, and a wide variety of other PSK and QAM formats
  • Support for custom modulation formats
  • Seamless integration of custom MATLAB code

Seamless Software Integration

Optical-LinQ is an intuitive and fully integrated software package for analysis of optically modulated signals. It runs entirely within the user interface of the LabMaster 10Zi-A. No other OMA on the market offers such integrated control of both oscilloscope and coherent receiver.

Optical-LinQ provides fully automated control of the IQS receiver, phase recovery algorithms, polarization demultiplexing, as well as an exhaustive number of modulation analysis displays and parameters.

Custom DSP Algorithm Validation

Test and validation of digital signal processing (DSP) algorithms is a vital part of the transceiver development. OpticalLinQ is equipped with built-in DSP algorithms such as CMA, MMA, Viterbi & Viterbi for you to use as tested reference algorithms. And the custom code integration feature lets you use and validate your own algorithms in MATLAB format.
