China Telecom selects Alcatel's optical multi-service gateways to expand its metro network in Northwest China
Aug. 7, 2001--Alcatel announced a multi-million dollar contract with China Telecom to expand the metropolitan network in Xi'an, the capital of Shaanxi Province, in Northwest China.
Alcatel, (Paris: CGEP.PA, NYSE: ALA), a provider of intelligent optical networking, announced a multi-million dollar contract with China Telecom to expand the metropolitan network in Xi'an, the capital of Shaanxi Province, in Northwest China. Under the deal, Alcatel will supply its naturally carrier-grade optical gateway, which will ensure a smooth build out of the city's information network architecture within the coming years.
Alcatel will deploy its Lambda Gate system in four key sites to flexibly interconnect the network fabric constituting Xi'an metropolitan transmission infrastructure. Interconnections will be implemented through a fully meshed network based on 10 Gbit/s interfaces integrated in the system directly. Designed to optimize network and switching costs, this optical solution offers a capacity extension over 5 Tbit/s.
Alcatel claims its Lambda Gate, a key part of Alcatel's Core Node, is the first multi-band switch to support any customized configuration for sub-wavelength aggregation and optical layer restoration. Core Node forms a unique integrated platform, which can scale independently in each transmission layer - optical, TDM or data -- along with specific service needs. Operators can thus closely match their network investments with revenue growth to maximize profitability even in the most uncertain market conditions.
Alcatel's Optical Gateways is designed to satisfy any customer requirement, providing sub-wavelength aggregation and switching solutions for all network layers -- from the optical layer to all TDM data layers. The Alcatel 1674 Lambda Gate, the core platform for the optical gateway, integrates network layers in one network element, thus reducing network complexity. The system allows for multi-service configurations, providing switching capacities up to 2.5 Tbit/s on 155Mbit/s level, and 3.2 Tbit/s on optical 10 Gbit/s level. It is an integral part of the Alcatel Core Node which provides from 640 Gbit/s to beyond 10 Tbit/s IP switching capability. The Alcatel 1674 Lambda Gate allows for the transport of 10 Gbit/s DWDM transmission flows, as well as SDH switching and routing capabilities, thanks to an optimized handling of the different network layers themselves and their inter-working in one single node. Furthermore, this system provides among other advantages growth on demand and scalability aligning revenues and investments, in-services upgrades and extensions, real-time signal and performance monitoring, and supports all conceivable networking applications.
Alcatel will also supply its integrated network management system to ensure end-to-end control, network protection and restoration, fast provisioning of services.
