Alcatel 1916 SDH
SDH / SONET integrated modules
Receiver STM-16 / OC-48 with Preamplifier EDFA
Description
These integrated modules are intended
for use in single channel transmission
with pre-amplifier EDFA in
combination with an optical filter. The
receiver contains an in-house III-V APD
(Avalanche Photodiode) detector with
preamplifier in a front-end module, a
main amplifier ASIC, a clock and data
recovery function with accurate
decision circuit. The modules are
housed in a space-saving 30-pin
package, providing the same electrical
access for overall applications. The
Alcatel 1916 SDH family is a range of
transmitter and receiver modules,
providing convenient and flexible
optical interfaces for SDH / SONET
systems operating at 2.488 Gbit/s &
2.666 Gbit/s and exceeds the
applicable ITU-T G.957, ITU-T G.783,
ITU-T G.692 and Bellcore GR-253
standards.

Applications
Used in transmission systems from
medium to high-speed for
intermediate-reach to long-reach
applications, the Alcatel 1900 SDH
family operates at SONET OC-3,
OC-12 and OC-48 rates as well as at
ITU-T SDH rates of STM-1, STM-4 and
STM-16. Covering all types of
SDH / SONET optical interfaces
(tributaries and aggregates) the
Alcatel 1900 SDH modules are
suitable for line systems, Add Drop
Multiplexers and digital cross-connects
as well as ATM switches.
As part of the Alcatel 1900 SDH
family, the Alcatel 1916 SDH module
is suited for all types of STM-16 (ShortHaul, Long-Haul, Very-Long-Haul and
Ultra-Long-Haul) and OC-48
(Intermediate-Reach, Long-Reach and
Ultra-Long-Reach) optical interfaces.
These modules ensure ease of use and
offer new flexibility to system designers.

DTA
Decision Threshold Adjustment:
input analog voltage that allows
optimization of the sensitivity
around the factory setting. When
DTA is opened the factory
setting is the default value.
LOS
Loss of Optical Signal : set when
the incoming optical power level
cross the alarm threshold. An
hysteresis is provided. Open
collector with internal pull-up.
The active level corresponds to
a 0 V voltage output level.
OIL
Optical Input Level : analog
information, proportional to the
optical input signal.
