Lucent announced that it has signed a contract with Zhejiang Telecom, a subsidiary of China Telecom, to build local optical transport networks in cities in Zhejiang province.
Under the terms of the contract, Lucent will supply a wide range of optical equipment including the LambdaUnite MultiService Switch (MSS), the WaveStar TDM 10G, the Metropolis ADM MultiService Mux (compact shelf), the Metropolis AM and network management systems, to assist Zhejiang Telecom in its effort to bring Ethernet services to its existing SDH network. Lucent's advanced optical products will help to double the capacity of Zhejiang Telecom's existing network and allow them to deliver a variety of new revenue-generating services.
Developed by Bell Labs, the LambdaUnite MSS bridges traffic between data-intense metro networks and high-speed optical core networks, connecting cities, campuses and corporate networks to larger, long-haul public networks. The product enables service providers like Zhejiang Telecom to seamlessly upgrade their networks and enables them to deliver new value-added services such as gigabit Ethernet. The compact size and low energy requirements of LambdaUnite MSS also means operators can make significant cost savings compared to traditional systems. This flexible single-shelf system was recently optimized for smaller metro applications, supporting in-service upgrades from 160G to 320G, as well as to 640G, allowing the system to grow when network capacity increases. Mesh restoration capabilities were also added to help carriers migrate to new mesh-based networks, while at the same time, leveraging traditional restoration architectures.
The Metropolis ADM MultiService Mux (compact shelf) serves as an integrated Ethernet over SDH metro access multiplexer, enabling service providers to migrate from existing time-division multiplexed (TDM) networks to data-aware packet networks. Zhejiang Telecom will be deploying the compact shelf with the TransLan card, which enables it to carry not only voice, but also data and other types of traffic. Metropolis AM, a compact and cost-effective Ethernet/SDH multiplexer, offers a wide selection of interfaces, allowing carriers to continue their traditional services while delivering new services.

The WaveStar TDM l0G (STM-64) will enable Zhejiang Telecom to deliver optical services at rates up to 10 Gb/s per wavelength and support currently commercialized and next-generation planned services through a scalable and flexible system. The system also allows carriers to reduce operating expenses through advanced self-healing networks and a superior carrier grade reliability. It offers flexible integration of Ethernet/SDH with Gigabit Ethernet capabilities. The integrated DWDM capability, based on Metropolis passive DWDM, provides for a cost-effective solution in metropolitan and backbone networks. Zhejiang Telecom is also deploying the Navis Optical W Management Solution, a portfolio of software products that provides comprehensive and integrated management solutions for optical transport networks, which will make it easy for them to integrate Lucent's products into their existing SDH network.
