Following on Xtera's Successful Deployment of the Longest All-Optical Link in Europe, Xtera Is Deploying the Highest Capacity All-Optical Network in Europe

Energis has selected Xtera Communications, Inc. as the multi-reach DWDM supplier for their next-generation backbone network in the United Kingdom. Xtera will construct the new optical backbone, supporting triple play services, with Nu-Wave, Xtera's multi-reach DWDM transport system that features optimum reach, enhanced bandwidth, and unprecedented Optical Add-Drop Multiplexer (OADM) flexibility and capacity. Furthermore, Xtera will be providing Energis with a comprehensive suite of services.

With Nu-Wave, Energis is using innovative Raman DWDM technology to create a national multi-service network providing high-capacity optical bandwidth to fifty locations throughout the United Kingdom. Once completed, Energis' new optical backbone will comprise more than 60 network elements, will span about 4,000 km and will exploit the full 100nm of bandwidth of the all-Raman Nu-Wave system. With Nu-Wave, Energis is able to minimize O-E-O transitions as well as reduce data aggregation layers in their network, therefore enabling them to provide low-jitter, low-latency services that are crucial to video and data applications. Nu-Wave's ability to place OADMs at any location, coupled with the capability to seamlessly upgrade, while in-service, in-line amplifier (ILA) sites to OADM sites provides Energis with the connectivity and flexibility required for their delivery of bandwidth intensive video and data services.

The flexible high-bandwidth architecture economically supports high-quality bandwidth for critical applications like the delivery of post-production video. Nu-Wave's unique combination of bandwidth and OADM flexibility enables Energis to mix broadcast applications, homing applications, and traditional ring-based applications on the same optical backbone. A resilient all-optical dual homing network architecture, combined with Nu-Wave's outstanding product reliability enables Energis to provide unsurpassed service availability to their customers. Additionally, using Nu-Wave's extensive optical monitoring capability combined with its intuitive management system, Energis can provide their customers with a detailed view of that customer's capacity. This functionality allows Energis' customers to directly monitor their purchased services in real-time.

"Using Nu-Wave's high-capacity multi-reach capabilities, we are able to simplify our national network and provide our customers with higher quality services, while lowering equipment and operational costs," said Energis' Business Development Director for the Media Sector, Alex Holt. Xtera CEO Jon Hopper commented, "Energis immediately saw the value of simplifying their network architecture using Nu-Wave, the industry's only actual Wide Reach™ DWDM transport solution with the headroom to deliver abundant high-quality video, data and advanced voice services. Using Nu-Wave, Energis is able to architect a next generation optical backbone that positions them to be the provider of choice in the UK for emerging data and video applications."
