Alcatel-Lucent 1692 Metrospan Edge

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.
