Alcatel-Lucent and Ciena Support SEA-ME-WE 4 Cable System Upgrade
By Rajani Baburajan, TMCnet Contributor
The Southeast Asia-Middle East-Western Europe 4 (SEA-ME-WE 4) cable system co-owners have selected telecom infrastructure equipment providers Alcatel-Lucent and Ciena for their network expansion project.
While Alcatel-Lucent (News - Alert) helps in the network upgrade to 40G (Gigabit per second) transmission of all the submarine segments, Ciena supplies optical switching equipment for all 16 cable landing sites and also 100G transport for an upgrade of the terrestrial link connecting Alexandria to Suez in Egypt.
The network expansion will start in the first quarter of 2011, and will support capacity increase to the existing cable system. SEA-ME-WE 4 is looking at an ultimate capacity of 2.4 Terabit per second per fiber pair. The capacity increase will support high-speed Internet and broadband services along the approximately 20,000 km route connecting Europe to the Middle East and Southeast Asia.
Alcatel-Lucent will deploy its 1620 Light Manager upgraded to 40G with coherent technology, and also upgrade part of the already installed 1678 Metro Core Connect on the terrestrial SDH side.
Ciena will deploy its multi-terabit ActivFlex 5430 Reconfigurable Switching System at cable landing stations and ActivFlex 6500 Packet-Optical Platform, equipped with coherent 100G optics, for the upgrade to 100G of the terrestrial link in Egypt and part of the terrestrial SDH, according to company officials.
Alcatel-Lucent, which leads the industry in terms of capacity and installed base with over 500,000 km of submarine networks, will upgrade its 1620 Light Manager with next-generation technology to offer 40G speeds.
Signal processing associated with coherent technology allows operators to handle transmission impairments in a cost-effective and automated manner. This flexibility in implementing different modulation formats enables Alcatel-Lucent to offer service providers the best technology option for new deployments and for existing networks.
Ciena will provide its ActivFlex 5430 with multi-terabit switching scalability. The company will also offer its ActivFlex 6500 with coherent 100G optics, electronic dispersion compensation, and directionless and colorless ROADM (News - Alert) functionality, according to company officials.
Back in November Alcatel-Lucent announced the launch of a Wireless Network Optimization Solution that enables operators to deal with mobile data traffic explosion. Read the full report here.
