New Optical Modulation Analyzer !
APEX Technologies with the collaboration of Alacatel Lucent III V Lab, the ENSSAT and the Telecom ParisTech graduate engineering schools are actually developing an Optical Modulation Analyzer. This Optical Modulation Analyzer is an optical oscilloscope with an ultra high linear sampling rate (> 112 Gbaud). 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 constellation, the eye diagram, the BER estimation and the EVM.
Here you can find a preliminary brochure of the Optical Linear Sampling Oscilloscope :
This equipment will be avilable begining of 2014 !
