Businesses have invested billions of dollars
in their SONET network infrastructures,
their operations systems, and the personnel
to run and maintain them. Customers,
both consumers and businesses, are now
demanding more services, more versatility
and more bandwidth, and these demands
are expected to continue to rise over the
next few years. Consequently, SONET
equipment is still called on to provide
transport for new and existing services.
Pressure for revenue growth means
that services must be deployed in the
here and now, without dramatic changes
to the network topology or to operational
methods. To fully use and expand the
capabilities of SONET, next-generation
transport solutions must be able to
aggregate disparate native channels at
differing bit rates, groom these signals
seamlessly, and then efficiently fill the
transport “pipes”.
The Alcatel-Lucent 1677 SONET
Link (SL) fulfills these requirements
by combining the functions of legacy
SONET add/drop multiplexers (ADMs),
the bandwidth-grooming capability of
narrowband, wideband and broadband
digital cross-connects, and the optical
fiber-sharing of dense wavelength division
multiplexing (DWDM). The Alcatel-Lucent
1677 SL offers best-in-class port densities
combined with the scalability that is
necessary for gradually adding more
services. What’s more, this class-leading
feature set comes at a realistic price.
YOUR NEEDS
Most operators have sufficient fiber in the
ground to support current and near-future
needs, provided that the fiber is used
effectively. In situations in which more
bandwidth is needed, they know that Alcatel-
Lucent has a full range of state-of-the-art
active and passive coarse wavelength
division multiplexing (CWDM) and DWDM
devices. What operators want is a network
element (NE) that leverages the existing
network, offers data and other services
via this network, and grooms signals at
the network edge. The NE must produce
substantial cost savings over incumbent
equipment by providing significantly
increased switching capacity and port
density, while at the same time controlling
heat output and power usage.
