Comcast and Ciena recently announced the successful completion of a 1 Tb/s optical transmission trial. Importantly, it is believed to be the first trial in which live data traffic was transmitted over a 1 Tb/s 16-QAM “super-channel” on an existing commercial network blended with 10G, 40G, and 100G wavelengths, proving that Comcast provides a clear path to the future while meeting today’s customer requirements.
