2 Alcatel-Lucent 1692 Metrospan Edge

The Alcatel-Lucent 1692 Metrospan Edge (MSE) is a compact and

competitively priced wavelength division multiplexing (WDM) solution

designed for cutting-edge multiprotocol transport systems. In metro -

politan areas, the explosion of high-bandwidth services, such as triple

play, video, 3G mobile, storage area network (SAN) extension and

enterprise Gigabit Ethernet (GigE), has dramatically increased the

band width required by telecom providers and vertical markets.

The Alcatel-Lucent 1692 MSE offers an excellent solution to meet this

challenge for service providers in metropolitan access networks, small

city core networks and private networks such as SANs. As the world

leader in optical networks, Alcatel-Lucent has deployed the Alcatel-

Lucent 1692 MSE in enterprise, core and access networks world wide.

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.

Bandwidth­intensive 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 Alcatel­Lucent’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.

A Cost-optimized System

The Alcatel-Lucent 1692 MSE is a
cost-optimized coarse WDM (CWDM)
transport system designed to meet the
requirements of enterprise and metro
access networks. This means that the
service provider or enterprise can start
with (and pay for) only the number of
channels and asso ciated equip ment
identified by short-term forecasts.
As the fore cast moves forward in time
and as demand increas es, the capacity
and number of wavelengths can be
increased. Alcatel-Lucent further
reduces its customers’ initial costs
by using small form-factor pluggable
(SFP) laser diode modules that do
not need to be pur chased until the
appropriate fibers are lit or new wave ­lengths are added. Over time, the
1692 MSE can easily be upgrad ed
(in situ) to the 1696 Metrospan,
allow ing the intro duction of dense
WDM (DWDM).

In addition to these low-cost SFP
modules, the Alcatel-Lucent 1692
MSE uses a sophisticated optical
mux/ demux unit that eliminates
the need for an expensive wavelength
con troller. This provides enterprises
and network opera tors with a low­cost CWDM system, perfectly suited
to short-haul and medium-haul
applications.

The Alcatel-Lucent 1692 MSE not
only provides reliable transport of new
revenue generating services for metro ­pol itan markets, but also offers a
low-cost solution for cost-sensitive
metropolitan access networks and
private networks. The Alcatel-Lucent
1692 MSE is a low-cost CWDM trans ­port system. It uses laser diodes spaced
at 20 nm, thereby relaxing require ­ments for the optical mux/demux
unit, and reducing the cost of com ­ponents. With the wide wavelength
range of CWDM, generally no
ampli fiers are required for ranges
less than 80 km.
