Mike,another article about DWDM and implications for Metro deployment.
Kenneth, just found another great article about MetroDWDM,coming from my biased reporting.

WDM products emerging this fall perform another set of new tasks: adding, dropping, and cross-connecting WDM wavelengths in meshed multipoint-to-multipoint networks. This set of capabilities represents a major advance in functionality for WDM beyond its current role of simply expanding fiber optic capacity between one point and another. So the new products hold out the promise to enable the launch of hundreds of wavelength-based services in metropolitan-area networks. For example, service providers could-perhaps by establishing virtual private networks (VPNs) on a wavelength-per-customer basis-begin creating gigabit Ethernet, fast Ethernet, ATM, or other protocol- and data-rate-independent private intranets or extranets on demand.
In other words, next-generation WDM equipment promises to enable the division of metro-area networks into optical "subnetworks" for specific customer VPNs, each configured, provisioned, and managed at the level of lightwaves. Several service providers are evaluating these and other new WDM approaches-with many on the brink of deployment.
Such a local wave explosion portends a tidal wave of new traffic to be exchanged and managed across regional, national, and international backbone networks. And a third set of WDM capabilities coming to market-end-to-end lightwave management across multiple local and long-distance networks-will help redirect the flood.
