Optical Complex Spectrum Analyzer

The principle is based upon the spectrum analysis of the optical field during which the amplitude and the relative phase of each spectral components of a modulated signal are analyzed.
By knowing the amplitude and phase of each spectral component, it can calculate the temporal variartion of the intensity and the phase of advanced modulation formats as QPSK, DP-QPSK, 16 QAM, 64 QAM… and display the eye diagram, the BER estimation and the EVM.

It is compatible with dual-polarization transmission.

It can characterize  waveforms and signals without any symbol rate limitation and can measure PRBS patterns.

Optical Linear Sampling Oscilloscope

This Optical oscilloscope with an ultra high linear sampling rate (>112 GBaud) can also measure the phase and be used as an Optical Modulation Analyzer.

It can measure the intensity and the phase of advanced modulation formats as QPSK, DP-QPSK, 16 QAM, 64 QAM… and display the phase, the intensity, the eye diagram, the BER estimation and the EVM.

It is compatible with dual-polarization transmission.

It can characterize  waveforms and signals at 40 Gbit/s, 100 Gbit/s, 400 Gbit/s, 1 Tbit/s and beyond.
