Comcast and Ciena Achieve 600Gbps Milestone Across long distance

Comcast together with Ciena recently conducted the world’s first long-distance 600Gbps single wavelength pilot deployment, which carried live commercial traffic across more than 800km between core peering locations in Newark, New Jersey, and Pittsburgh, Pennsylvania. To test the full capabilities of the technology, Comcast also looped back the signal and verified successful operation of 600Gbps across 1,600-kilometers.

Key Facts:
• Comcast Labs and Network Engineering teams achieved two times increase in wavelength capacity across the mixed fiber link while leveraging Ciena’s WL5e technology. As the industry’s first programmable 800G solution, WaveLogic 5 Extreme is designed to provide unmatched bandwidth tunability, from 200G to 800G, and adapt to constantly changing end-user demands with more capacity per wavelength and lower cost per bit.

• The deployment of WL5e on the link between Newark and Pittsburgh is the first in Ciena’s Waveserver 5 form factor. Waveserver 5 leverages WaveLogic 5 coherent technology to scale up to 12.8Tbps in a compact 2RU footprint, allowing Comcast to maximize fiber capacity and reduce the amount of hardware required to support high-bandwidth service growth.

• In addition to capacity upgrades, WL5e facilitates the evolution to 400G-interface routers and universal 400GbE transport across any location in the Comcast National Backbone network without regeneration. This capability will allow Comcast to continue scaling its network at the pace of its business, with less power and lower overall costs.
