Xtera intros Nu-Wave ES

JUNE 11 2007 -- Until now, the pay-as-you-grow strategies for DWDM systems have been limited to the terminals. Nu-Wave ES extends the concept to include the optical line system, say Xtera representatives.

JUNE 11 2007 -- Xtera Communications (search for Xtera Communications) today announced the introduction of Nu-Wave ES, its latest all-Raman optical line system, which it says is designed to significantly lower the start-up cost of highly scaleable optical networks and redefine the pay-as-you-grow paradigm.

Xtera says the unparalleled performance of all-Raman (search for Raman) amplification allows service providers to extend transmission distance and simultaneously support three times the capacity of erbium-doped fiber amplifier (EDFA)-based networks. This type of all-Raman performance simplifies the delivery of high-capacity next-generation IP and video services, opening up new markets for business, computing, media and entertainment applications.

In fact, Xtera says "all-Raman performance" has been deployed to overcome the challenging demands of a 4,000-km multi-terabit post-production video network where the technology enabled a high percentage of OADM nodes across the network, providing easy access to high-quality bandwidth for compressed and uncompressed video applications. It has also been used to demonstrate next-generation IP-over-DWDM service delivery using the latest 40-Gbit/sec router, say company representatives. The demonstration, which occurred over a record-breaking 3,040 km, showed that service providers could maximize use of their current fiber infrastructure to deliver existing and emerging services.

"Recent developments in Raman amplification have allowed Xtera to develop the world's first ultra-scaleable line system to significantly reduce the start-up cost of a high-performance next generation network," contends Herve Fevrier, COO of Xtera Communications. The technology is used within Xtera's latest all-Raman optical line system, Nu-Wave ES, to minimize start-up costs without compromising the ultimate capacity of the network, he says.

"While we are very pleased with the overall progress of Xtera having reached profitability in fiscal year 2006 and completed successful deployments throughout Europe, The Middle East, Asia, South America, and North America, we recognized the need to offer a highly scaleable system that not only substantially lowers the day one costs of our customers, but also lowers our cost of goods sold by over 70%, opening much larger segments of the market to Xtera," adds Xtera CEO Jon Hopper.

Until now, the pay-as-you-grow strategies for DWDM systems have been limited to the terminals. Nu-Wave ES extends the concept to include the optical line system. The Nu-Wave ES optical line system can be deployed at a cost-saving capacity of 30 wavelengths and can grow to an ultimate capacity of 150 wavelengths, says the company. Nu-Wave ES can be deployed in a highly scaleable multi-degree node configuration to enable service resiliency and bandwidth efficiency and facilitate even more network-level savings, note company representatives.
