Corenet selects ECI Telecom for advanced ROADM network

MARCH 15, 2007 -- The key building blocks in this deployment are wavelength-selective switch (WSS)-based ROADMs, full support of Optical Transport Network for all services, and "SDH-like" wavelength management, say ECI representatives.

MARCH 15, 2007 -- ECI Telecom (search for ECI Telecom) today announced that Corenet, a leading provider of telecommunication services in Finland, has selected ECI Telecom's XDM all range reconfigurable optical add/drop multiplexer (search for ROADM) platform for deployment of one of Europe's first and most advanced ROADM mesh networks. The key building blocks in this deployment are wavelength-selective switch (WSS)-based ROADMs, full support of Optical Transport Network (search for OTN) for all services, and "SDH-like" wavelength management.

ECI says its ROADM network will allow Corenet to swiftly lease high-speed wavelength and sub-wavelength services across the region, meeting the needs of its customers, including international carriers who connect Russia and Far East states with Western Europe. With this ROADM network, Corenet also is able to provide TDM and data services cost-effectively to enterprise customers, such as Research and Educational Networks (RENs) and government facilities.

"Many carriers around the world are deploying multi-degree ROADMs in order to introduce agility and scalability into their DWDM networks, with the advantage of greatly quickening time to market for new services," reports Michael Howard, principal analyst at Infonetics Research. "Built on a mesh topology with multi-degree WSS ROADMs and tunable lasers in all nodes, the Corenet network is clearly one of the most advanced in Europe."

By deploying WSS ROADMs and 10-Gbit/sec widely tunable transponders, ECI will enable Corenet to easily and quickly provision services from any node to any node across the entire nationwide network, while dramatically cutting OPEX, claims the company. In addition, by relying on full OTN mapping and multiplexing of all services, including 10-Gigabit Ethernet LAN, high-power variable-gain amplifiers and automatic power balancing, Corenet will be able to offer fully transparent SDH and data services with high quality-of-service (QoS) and interoperate with other carriers, say ECI representatives. Corenet will also be able to add 40-Gbit/sec services to the network, once necessary.

This new ROADM network will be deployed as an expansion to the existing XDM-based MSPP and DWDM backbone of Corenet, and the entire network is managed by ECI's LightSoftV3 management system.

"ECI's solution meets and exceeds our needs and expectations for a state-of-the-art technology to provide our customers with the most advanced services on the market in a quick, reliable, and cost-effective way," notes Jouko Tervo, CEO of Corenet. "ECI's comprehensive management system, LightSoft, gave us the additional validation to choose this solution."
