As Datacom/Telecom application spaces continue to evolve and converge- driven by exponential demand for information bandwidth- a move to higher efficiency use of the available information bandwidth is being enabled by advanced modulation techniques. Client-side networks are quickly adopting PAM-4 signaling schemes, whereas line-side applications are now widely deploying coherent systems driven by QPSK/QAM (amplitude or phase modulated) coherent signaling methods.

From the electrical interconnect all the way to metro regional and long haul optical links, Teledyne LeCroy's superior measurement and analysis toolbox reliably addresses the measurement requirements brought about by the introduction of advanced modulation techniques such as PAM-4 and QPSK. Whether in 56GBaud Datacenter interconnects or 400Gb/s Line Side links, Teledyne LeCroy 's Test Solutions deliver the performance that gets the job done
