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 -
nec tivity and protocol require ments. 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.
