Alcatel 1926 SDH SDH / SONET integrated modules Multi-Source Compact Transmitter STM-16 STM-16 / OC-48 OC-48 Description These integrated modules are intended to be used at SDH and SONET bit rates. The Alcatel 1926 SDH family is a range of compact transmitter modules and compact receiver modules, providing convenient and flexible interfaces for SDH / SONET systems operating at 2.488 Gbit/s and compliant with ITU-T G.957 & G.783 and Telcordia GR-253-CORE GR-253-CORE standards. The transmitter module contains an in-house uncooled laser diode module with a selectable retiming and laser driver. The module is housed in a space-saving 24-pin package, providing the same electrical access for overall applications. Features · New International Standard · Multisource Optical Interfaces · Space-saving package and minimizing cost · Upward compatibility with different features · Operating 1.3 µm wavelength. · Full performance in case temperature range - 5 °C to + 75 °C and - 40 °C to + 85 °C · Single power supply + 5V or - 5.2 V · Power consumption, 0.8 W typical · Alcatel Reliability and Qualification Program for built in quality · Uncooled FP or DFB laser · Clocked or Non-Clocked selectable · Up to 40 km span · Ultra low jitter generation · Digital laser degraded alarm · Back face monitor output Applications Used in transmission systems for Long Haul, Metro, Enterprise and Access markets, the Alcatel 1900 SDH family operates at SONET OC-3, OC-12 OC-12 and OC-48 OC-48 rates as well as at ITU-T SDH rates of STM-1, STM-4 and STM-16 STM-16. Covering all types of SDH / SONET optical interfaces (tributaries and aggregates) the Alcatel 1900 SDH modules are suitable for line systems, local loop systems, Add Drop Multiplexers and digital cross-connects as well as ATM systems. As part of the Alcatel 1900 SDH family, the Alcatel 1926 SDH module is suited for all types of STM-16 STM-16 (Intra-Office, Short Haul, Long Haul, Very Long Haul) and OC-48 OC-48 (Short-Reach, IntermediateReach and Long-Reach) optical interfaces. These modules ensure ease of use and offer new flexibility to system designers. Finally, Alcatel 1926 SDH module is the ideal solution for the exploding 2.5 Gbit/s market.
