Comcast Conducts Industry's First Live 1Terabit Network Trial with Ciena's 6500 Converged Packet Optical Solution

09:00 EDT Tuesday, October 22, 2013

HANOVER, Md. & PHILADELPHIA (Business Wire) -- Comcast (Nasdaq: CMCSA, CMCSK) and Ciena® Corporation (Nasdaq: CIEN), the network specialist, successfully completed a live field trial of a 1Terabit/sec (Tb/s) optical transmission spanning nearly 1,000 km. By demonstrating the ability to increase the traffic carrying capacity by 2.5 times, this trial showed how Comcast's existing fiber network can scale to keep pace with the bandwidth demands of cloud computing, video, and multimedia applications, as well as data center connectivity. The companies made the announcement today at the SCTE Tec-Expo taking place at the Georgia World Congress Center in Atlanta.

The 1Tb/s trial took place during the first week of October over Comcast's existing long-haul fiber infrastructure connecting Ashburn, Va. to Charlotte, N.C. This is believed to be the first trial in which live data traffic was carried over a 1Tb/s 16QAM super-channel on an existing, commercial network. At the same time, that network was also carrying customer traffic over 10G, 40G and 100G wavelengths, all coexisting on a mix of flexible and 50GHz-spacedfixed grid channels.

The 1Tb/s trial used Ciena's 6500 Packet-Optical Platform solution that combined flexible grid Reconfigurable Optical Add/Drop Multiplexers (ROADM) with 16QAM coherent modulation to achieve 5b/s/Hz of spectral efficiency over a distance of nearly 1,000 km of uncompensated ELEAF fiber. Ciena's next generation Raman and programmable gain amplifiers, the newest addition to the WaveLogic intelligent coherent portfolio, provided optimized performance and system reach. The trial ran in parallel over the same optical infrastructure that supports a combination of HD video, Internet and voice traffic on Comcast's existing 100G national backbone.

“We continue to work with Ciena to leverage our already installed Ciena 6500 platforms to deliver more content, faster Internet speeds and enable new cloud-based applications for our customers,” said Steve Surdam executive director, Network Engineering at Comcast Cable. “As we look to continuously evolve our network infrastructure, Ciena's high-capacity Terabit optical technology will give us the flexibility and scalability required to future proof our network to deliver next-generation products and services for our customers.”

The success of this trial was made possible via the joint collaboration of Ciena and Comcast throughout the entire process – from strategy and engineering to configuration and execution.

“Innovative service providers like Comcast know that they can rely on Ciena's field-proven, industry-leading converged packet optical technology to keep pace with today's surging bandwidth requirements. Our technology goes beyond scaling bandwidth to make the network more intelligent and responsive to service and application needs, which is the basis of Ciena's OPn architecture approach and increasingly critical in today's highly competitive environment,” said Francois Locoh-Donou, senior vice president, Global Products Group at Ciena. “This trial is a significant accomplishment because it took place across a production network and demonstrated our ability to extend the scalability benefits of new coherent modulation techniques beyond metro and regional distances.”

At the SCTE event, Ciena (booth #1326) will showcase advanced packet optical solutions, including the 6500 shelf equipped with the Terabit super-channel technology used in the trial with Comcast.

Comcast has been leveraging Ciena's coherent 40G and 100G technologies across its national fiber network since 2009. Ciena's packet networking solutions also support Comcast's Metro Ethernet services offering.
