7 January 2004 Beijing, China Lightwave -- Lucent Technologies has signed a contract with Wenzhou Telecom, a subsidiary of Zhejiang Telecom, to help improve its network capacity in China's Wenzhou province. Lucent's advanced optical networking products will be used in the reconstruction of Wenzhou Telecom's SDH network, increasing the network's transport capacity and enabling new revenue-generating services.
Per the contract, Lucent will supply the LambdaUnite MultiService Switch (MSS), Metropolis ADM MultiService Mux, the WaveStar TDM 10G, and the WaveStar(R) ADM 16/1. According to Lucent representatives, these products will help Wenzhou Telecom build a cost-effective optical network that supports both voice and data traffic and will allow Wenzhou to offer Ethernet, personal handy-phone system (PHS) and transport-based data services to its customers.
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 Wenzhou Telecom to upgrade their networks and deliver new value-added services such as Gigabit Ethernet. The compact size and low energy requirements of LambdaUniteMSS also mean operators can make significant cost savings compared to traditional systems, claims Lucent. The single-shelf system was recently optimized for smaller metro applications, supporting in-service upgrades from 160 Gbits/sec to 320 Gbits/sec, as well as to 640 Gbits/sec, 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 leveraging traditional restoration architectures.
The Metropolis ADM serves as an integrated Ethernet-over-SDH multiplexer, enabling carriers to migrate from existing TDM networks to data-aware packet networks. Adding data services to optical networks increases revenue potential for customers and helps them offer a wide variety of new Ethernet services, explain Lucent representatives. The Metropolis ADM integrates seamlessly into carriers' existing infrastructure, avoiding the need for an overlay network built for new services. Its low power consumption and small footprint will further help carriers save on operating expenses.
The WaveStar TDM 10G (STM-64) will enable Wenzhou Telecom to deliver optical services at rates up to 10 Gbits/sec 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 carrier-grade reliability, says the company. The WaveStar ADM also offers flexible integration of Ethernet/SDH with Gigabit Ethernet capabilities. Because it combines multiple low-speed electrical and optical inputs into a single 2.5-Gbit/sec signal, the multiplexer can be used for interoffice, access, or regional applications.
