ECI's innovative Multi-Degree WSS ROADM platform used for true mesh network

20 марта 2007
Corenet, a leading provider of state-of-the-art telecommunication services in Finland, has selected ECI Telecom's XDM all range(TM) ROADM platform for deployment of one of Europe's first and most advanced ROADM mesh networks. The key building blocks in this deployment are WSS ROADMs, full support of Optical Transport Network (OTN) for all services and "SDH-like” wavelength management. ECI's advanced 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 is also 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”, said 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 10Gbps 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. In addition, by relying on full OTN mapping and multiplexing of all services, including 10GE LAN, high-power variable-gain amplifiers and automatic power balancing, Corenet will be able to offer fully transparent SDH and data services with high QoS and interoperate with other carriers. Corenet will also be able to seamlessly add 40Gbps 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 LightSoft V3 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,” said Jouko Tervo, CEO of Corenet. "ECI's comprehensive management system, LightSoft, gave us the additional validation to choose this solution."

"ECI is honored to be part of one of Europe's most advanced ROADM networks,” said Shimon Levany, President for North-West Europe at ECI Telecom. "As a carrier of carriers, Corenet operates in a very dynamic market, and this network allows them to edge ahead of their competitors. ECI's clear leadership in the optical arena, along with our focus on the Utelco & carrier of carriers' market, were important decision points for Corenet."
