High Speed Networks: SONET/SDH, OTN, WDM, 40/100/400G NEMs and Lab WDM/SONET/OTN transport testing

This webinar reviews the methods and tools that can be used to quickly and accurately test 100G transmitters, like constellation diagrams, eye diagrams and error vector magnitude measurement. It also focuses on the differences between coherent transmitter analysis via optical sampling and electrical sampling. Finally, common transmitter impairments are discussed as well as a novel approach that uses masks to avoid having to interpret complex test results.
