Telewest Installs New METROLink(TM) Transport System To Upgrade
Infrastructure For Extended Digital Service Offerings
In another example of the growing use of dense wave division multiplexing (spelling) wave division multiplexing - A common misnomer for wavelength division multiplexing. (DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM.
DWDM - wavelength division multiplexing ) technology, Harmonic Inc. (Nasdaq: HLIT) today announced that Telewest Broadband has installed Harmonic's METROLink(TM) DWDM transmission system in the upgrade of its system in the Southwest of England. With its ability to multiplex See multiplexing. up to 32 wavelengths at 100-GHz (0.8 nm) spacing on a single fiber, the METROLink DWDM system enables Telewest to increase the capacity of its network and deliver narrowcast To transmit to selected individuals. Cable TV and satellite radio are examples of narrowcast services because they reach only their subscriber base. Mailing lists are another example. Contrast with broadcast. See multicast. and multicast services to residential and business customers. Telewest's upgrade of its network represents the first ever deployment of 100-GHz DWDM solutions in the cable market.
The geographical area covered by Telewest's upgrade presented a unique set of challenges for implementing a balanced and scalable network architecture. First, the region is characterized by a mix of high- and low-density areas of population as well as short- and medium-distance links. Second, Telewest's existing network comprised several different architectures. A comprehensive DWDM system, Harmonic's METROLink solution provided the flexibility needed for a network that reaches both urban and rural areas. Harmonic's 100-GHz DWDM transmission solution integrated seamlessly into the Telewest environment using wavelengths that were below the window occupied by existing 1550-nm trunk transmitters. This approach gives Telewest the narrowcast/broadcast infrastructure required to support a variety of bandwidth-intensive voice, data and video services.
"Adoption rates of our voice and data services have necessitated an upgrade of our existing network infrastructure so that we can deliver interactive services more efficiently to our geographically distributed customer base and add incremental capacity in step with growing demand," said Chris Eccles, Telewest's Network Architect HFC 1.

"Harmonic's DWDM technology leadership and proven solutions combined with its responsiveness and ability to meet our specific requirements made it the logical choice for this major initiative. The new 100-GHz METROLink solution integrated quickly and easily with our existing equipment."
Providers like Telewest are increasingly choosing DWDM-based architectures for their cost-effectiveness, scalability and flexibility. DWDM gives these operators the capacity needed to provision current and emerging interactive services. New capacity can be brought online incrementally to support new target services or to increase bandwidth for existing services. In the late 1990s, Harmonic became the first company to provide DWDM transmission systems to the cable market. Since then, Harmonic has established itself as a leading provider of these technologies, enabling broadband communications service providers A Communications Service Provider or CSP is a company that transports information electronically. The term encompasses public and private companies in the wireline, wireless, Internet, cable, satellite, and managed services businesses. to build balanced and scalable, pay-as-you-grow network architectures optimized to deliver a wide range of one- and two-way services.
"By upgrading to DWDM technology, Telewest has implemented a highly efficient architecture for cost-effectively delivering fast and reliable digital broadcast and narrowcast services," said Frank Patterson, Harmonic's Sales Director for UK, Middle East and Southern Africa
