High resolution optical complex spectrum analyzer OCSA (down to 5 MHz / 80 fm) in the telecommunication range; Time domain analysis available: Intensity & Phase vs. time, Eye diagram, Constellation, Chirp, BER, Chromatic dispersion, etc.

Optical Modulation Analyzer Features:

No Baud rate limitation
No modulation format limitation (BPSK, DPSK, QPSK, DP-QPSK, 16QAM, 64QAM…)
PRBS patterns analysis
Polarization diversity
Phase, chirp, intensity vs time – Constellation – Eye diagram – Chromatic dispersion

High performance and cost effective solution for Telecommunication applications. The AP268x Series is equiped with the high resolution of 5 MHz/0.04 pm, 20 MHz/0.16 pm, 100 MHz/0.8 pm, as well as other resolution bandwidth from 140 MHz to 250 GHz. Analysis of optical signal in both polarization axis is possible due to the two polarization channels inside. The direct access to each channel is available.

Available options:
– the optical output of the built-in Tunable Laser Source (TLS), which could also be used for component analysis (tracking funciton);
– additional PM inputs for each polarization channel;
– optical filtered ouput + polarimeter;
– Chromatic dispersion measurement
