<This is a mystery to me? I already thought Nortel has some leading edge DWDM technology and equipment. I'm fairly certain this is the case.> They already were #1 in DWDM but isn't this product (Metro DWDM) different than DWDM over SONET? Seems like they are determined to be No. 1 in this sector. Their market share for DWDM should be huge. Ken

Mike & Thread - Here is a press release from Newbridge on sale of Cambrian to Nortel. Wednesday December 9, 7:31 am Eastern Time Company Press Release Newbridge Networks Sells Ownership Stake in Cambrian Systems Corporation KANATA, ONTARIO--Newbridge Maintains Full Access to Cambrian DWDM Technology and Realizes Significant Value to Newbridge Shareholders Newbridge Networks (NYSE: NN - news; TSE: NNC - news) today announced it has agreed to sell its approximately 40 percent ownership position in Cambrian Systems Corporation to Nortel Networks. The transaction values Cambrian at up to US$300 million. The existing OEM a greement between Newbridge and Cambrian will continue under Nortel's ownership of Cambrian to ensure Newbridge has access to Cambrian's dense wave division multiplexing (DWDM) products. ''Our relationship with Cambrian over the past couple of years has enabled us to take the lead in integrating DWDM technology into our multi-services ATM platform,'' said Alan Lutz, President and Chief Operating Officer, Newbridge Networks. ''Our agreement with Nortel Networks ensures that our customers' requirements for an integrated DWDM-ATM solution will continue to be met and at the same time allows Newbridge to consider the DWDM technologies of other vendors for Newbridge(r) distributed ATM solutions .'' Newbridge was the first vendor to demonstrate an integrated DWDM-ATM solution designed specifically for metropolitan area networks (MANs) when it unveiled the product in October at Networld+Interop in Atlanta, Georgia. The scalable, cost-effective solut ion combines DWDM-based transport with an ATM core infrastructure to deliver broadband services from a seamless, fully managed platform. Deployed on the industry-leading Siemens / Newbridge MainStreetXpress(tm) 36170 MultiServices Switch, the ATM/DWDM integrated switching and transport platform enables service providers to maximize usage of their existing optical fiber cable infrastructur e. By integrating switching and transport into a seamless system, service providers can simplify their overall network architecture, enhance their network and service management capabilities, and reduce their capital and operational costs. The sale of Cambrian also demonstrates the growing dynamism and momentum of the Newbridge Affiliate program and its focus on bringing advanced technologies to market quickly and cost effectively while maximizing value to Newbridge and its shareholders. In September, Newbridge announced the sale of Advanced Computer Communications (ACC) to Ericsson for US$285 million, a transaction that enables Newbridge to maintain its existing business relationships with ACC, including joint research and development p rograms and manufacturing and reseller arrangements for the entire ACC product line. ''The Newbridge Affiliate program enables the Newbridge family of companies to develop a comprehensive array of complementary products and technologies that provide total networking solutions to our customers,'' said Mr. Lutz. ''The program and our commitm ent to it will continue to expand. The proceeds from this transaction bring the ability for even greater flexibility to the program.'' Newbridge Networks designs, manufactures, markets and services networking solutions to organizations in more than 100 countries. The Company leverages its relationship with a growing family of Affiliate companies and strategic alliances with Siemens and 3Com Corporation to deliver seamless, end-to-end solutions. Newbridge customers include the world's 300 largest telecommunications service providers and more than 10,000 corporations, government organizations and other institutions. Founded in 1986, th e Company employs more than 6,000 people on five continents. News and information are available at www.newbridge.com.

Mike,some good articles in internettelephony.com Now, Clavenna says, "Vendors and carriers aren't quite as excited about the all-optical network as they were a few years ago. They are seeing value in having electrical processing occur at different points in the network. There are benefits to be able to examine the signal electrically." One of the most important benefits is that an electrical matrix provides for Sonet reliability. Until something equivalent emerges in the optical domain, carriers will stick to Sonet, and vendors will implement optical-electrical-optical conversion. Alcatel supports the vision of a photonic network rather than an all-optical network. "The big benefit of photonic switching is [that it operates] independent of rate and format," says Tim Krause, director of product line management for optical networks at Alcatel. But photonic switching can't regenerate signals or monitor performance. Today, regeneration requires electrical-optical-electrical conversion. Krause predicts that all-optical switches will emerge in the metropolitan environment first. "In a metro application you don't need to worry about regeneration required in a long-distance network, but you do want a tremendous amount of transparency," he says. Photonic optical cross-connects will move into the backbone later, adds Philippe Perrier, product manger for optical cross-connects in Alcatel's optical networks group. "It is difficult to make an electrical matrix work at 10 Gb/s, but an optical cross-connect with photonics can do it," he says. Bellcore spinoff Tellium points out that the ability of its Aurora wavelength-converting cross-connect (Figure 4) to convert all incoming signals to 1310 nm for output allows otherwise non-interoperable systems to work together (see sidebar opposite). That saves money for merging networks and interconnection arrangements. NT does has a plethora of Optical DWDM products. Hiram
