Alcatel 1916 SDH
SDH / SONET integrated modules
Receiver STM-16 / OC-48 with Preamplifier EDFA
Description
• Data Reshaping
• Clock recovery & Data Retiming
• Convenient digital alarms to
minimize external circuitry
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
• Analog information for flexible
integration
• Common pin-out for all modules
• Alcatel Reliability and Qualification
Program for built in quality
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
applicable ITU-T G.957, ITU-T G.783,
ITU-T G.692 and Bellcore GR-253
standards.
suitable for line systems, Add Drop
Multiplexers and digital cross-connects
as well as ATM switches.
Features
As part of the Alcatel 1900 SDH
family, the Alcatel 1916 SDH module
is suited for all types of STM-16 (Short-
Haul, 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.
