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.

Key Features
The Alcatel-Lucent 1692 MSE:
• Optimizes the transport of a bundle of signals, groomed according to a synchronouscompliant frame structure, using dedicated TDM transponders
• Supports rapid roll-outs of new services
• Transparently transports multiple protocols (SONET/SDH, SAN, IP, video)
on a single wavelength
• Provides optical layer protection (e.g., optical multiplexing section protection [OMSP]
and optical channel subnetwork connection protection [OCH-SNCP])
With so much functionality and scalability packed into a 3 rack unit (RU) (5¼ inch) compact
shelf, the Alcatel-Lucent 1692 MSE stands out from its competition. First, it is designed to
minimize initial CAPEX and support ever-growing traffic volumes on an incre mental basis.
Second, its well-known and trusted 4xAny/2xGE-FC concentrators groom traffic and fill
transport pipes in a flexible and non-blocking manner. Third, native signals such as IP, IP
video, ATM and data are transported transparently to the end user with optical channel
protection/restoration safeguards. And fourth, class-leading scalability allows the Alcatel-Lucent
1692 MSE solution to grow to support sixteen discrete ITU wavelengths, enabling an unsur passed per-fiber bandwidth yield.
Table 1 lists the benefits, features and functions of the Alcatel-Lucent 1692 MSE.

6 Alcatel-Lucent 1692 Metrospan Edge
The Alcatel-Lucent 1692 MSE sup ports up to 16 wavelengths sustain ing
variable-rate and fixed-rate optical
interfaces, capable of accepting a
broad range of data rates. Dedicated
TDM concentrators (4xAny card and
2xGE-FC card) are available to opti mize transportation of a bundle of
signals, groomed accordingly to a syn chronous frame structure. These cards
reduce the cost of each client service
and maximize optical channel usage.
The Alcatel-Lucent 1692 MSE’s
4xAny concentrator card can multi plex up to 4 low-speed client signals
(for example OC-3/12, ATM1/4, FE,
GE, FC etc.) to one OC-48 signal.
The 2xGE-FC card multiplexes
two GigE or FC signals using the
transparent-mapped generic framing
procedure (GFP-T) standard. A small
number of backup cards, (compact
in size and low in power consumption)
keep the operation, administration,
and maintenance (OAM) costs of
the Alcatel-Lucent1692 MSE low.
Tributary cards for the Alcatel-Lucent
1692 MSE have hot plug-and-play
optics; this permits customization of
the transponder, resulting in increased
flexibility of the product.
Technical Superiority
7Alcatel-Lucent 1692 Metrospan Edge
Fully scalable from two wavelengths
up to 16, the Alcatel-Lucent 1692
MSE allows service providers to
purchase only the capacity required
and then to increase capacity only
as consumer demand increases. That
is, as requirements change over time,
the system’s manageability and func tionality can be adapted in incre mental steps.
Adaptable solutions allow quick
reaction to rapidly changing market
conditions and ensure timely imple mentation of new services. The
Alcatel-Lucent 1692 MSE ensures
that combinations of very different
client services (SONET/SDH, SAN,
IP, video) can be transported trans parently on a single wavelength,
without the need to upgrade the
whole network; this shortens the
overall time-to-market and increases
the number of services that can be
delivered. Each wavelength can be
unidirectional or bidirectional. The
Alcatel-Lucent 1692 MSE tributary
cards feature hot plug-and-play optics,
so the user can customize provi sioning
while the remainder of the NE is
under load.
Ultimate Scalability and Versatility
8 Alcatel-Lucent 1692 Metrospan Edge
The Alcatel-Lucent 1692 MSE sup ports point-to-point links and ring
networks with coarse optical add/drop
multiplexer (COADM) technology.
The terminal can support up to
16 wavelengths of unidi rectional
transmission or 4 wave lengths of
one fiber bidirectional transmission.
The back-to-back terminal, which
normally is used as the hub node in
a ring network, can add/drop 16 wave lengths. The COADM node can
add/drop 1, 2 or 4 wavelengths for
unidirectional application, while
it adds/drops one channel for a one
fiber bidirectional application. There
are two types of CPE: one channel
CPEs and two channel CPEs; this
provides a cost-effective solution
when the remote network node has
only one channel.
Figure 2 shows a two fiber ring
network.
With the Alcatel-Lucent 1692 MSE,
data applications are easily imple mented
and network expansions, based on
end-user demand, are sim plified. Easy
to install, operate and maintain, the
Alcatel-Lucent 1692 MSE allows
enterprise and network operators
to simplify their overall deployment
process, directly improv ing both
CAPEX and OPEX. No amplification
is required for short-haul applications;
however if longer reaches are required,
electrical regen eration can be provided
for distances greater than 80 km.
With temperature-hardened compo nents, the Alcatel-Lucent 1692 MSE
can be installed in virtually any
network environment, from a
basement closet to a central office.
The Alcatel-Lucent 1692 MSE sup ports the following network topologies:
• Ring networks
• Point-to-point links
• CPE configuration in point-topoint links
• CPE configuration in ring networks
