Understanding Phase Modulation For 100G Transmission

On , in All Posts, General, Line Side, by Tony Goodchild

There are a number of challenges to achieving 100Gb/s optical transmission rates using the technologies that have been deployed at 10Gb/s and even 40Gb/s. Using traditional transmission technologies such as NRZ modulation on the line will result in very poor spectral efficiency and a 100G signal using NRZ would not fit into the standard 50GHz […]
