Operational Efficiency of Super-Channels

Eve Griliches, ACG Research, and Dave Welch, Infinera, discuss the benefits of flexible modulation and OTN integration

Watch Eve Griliches, packet optical analyst at ACG Research and Dave Welch, cofounder and executive vice president at Infinera, explain, using an example, the operational efficiency of super-channels, the benefits of flexible modulation and OTN integration.

Infinera has integrated the OTN fabric into the DTN-X, providing significant operational benefit while meeting power, footprint and bandwidth requirements. With bandwidth outpacing chip development, super-channels are the key technology to enable higher bandwidth deployment today.

Eve and Dave explain why 16-QAM is limited in reach for all vendors and carriers, and what the implementation penalties are. They also discuss the increased spectral efficiency and how it is still a win-win for shorter, highly concentrated routes and how with one line card in the DTN-X, you can configure sub-terrestrial distances and high bandwidth congested routes, which enables a new paradigm for optical networking.
