Customer Requirements
Today’s competitive environment places taxing demands on service providers, forcing them to drive down costs and reduce the complexity of their networks and operations. Bandwidth- intensive services such as triple play, video, 3G mobile, SAN extension and enterprise GigE, are already placing greater demands on these networks. The Alcatel-Lucent 1692 MSE targets metro access service providers as well as vertical markets, and enterprises. Using WDM, the Alcatel-Lucent 1692 MSE allows service pro- viders and enterprises to meet continually increasing bandwidth requirements by increas- ing the capacity of each available optical fiber. In addition, the Alcatel-Lucent 1692 MSE simplifies network planning, speeds up wave- length provisioning and eases the overall maintenance load required for enterprise and metro access optical transport networks.
An Entirely Optical Network
The Alcatel-Lucent 1692 MSE is part of Alcatel- Lucent’s vision for an entirely optical network: a network that provides all the functions of the SONET/SDH layer including routing, wave- length add/drop and survivability. The various protocols present in metropolitan areas benefit by having the Alcatel-Lucent 1692 MSE as the common platform upon which to develop con- nectivity and protocol requirements. The Alcatel-Lucent 1692 MSE includes the same winning features as those of the Alcatel-Lucent WDM product family but with key differentiators that further reduce purchasing and operating costs. Figure 1 illustrates both the central office and the compact versions of the Alcatel-Lucent 1692 MSE in a metro WDM network.
