Alcatel 1916 SDH SDH / SONET integrated modules Receiver STM-16 / OC-48 for D-WDM Description These integrated modules are intended for use Dense Wavelength Division Multiplex (D-WDM) at SDH and SONET bit rates with a lot of noise on the optical links with several EDFAs. 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.691 and Bellcore GR-253 standards. Features • D-WDM receivers for Ultra-LongHaul : 6 400 ps/nm (320 km) 12 800 ps/nm (640 km) • Bit rate 2.488 Gbit/s & 2.666 Gbit/s (FEC) • Operate with high noise : up to S/N = 14 dB / 0.1 nm at 2.666 Gbit/s (FEC) up to S/N = 19 dB / 0.1 nm at 2. 488 Gbit/s • Operating 1.5 µm wavelength • Full performance in operating case temperature from 0 to + 70 °C • Low power consumption • Small size less than 100 cm2 • Data Reshaping • Clock recovery & Data Retiming • Convenient digital alarms to minimize external circuitry • 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 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.
