Alcatel 1916 LMM
12800 ps/nm WDM 2.5 Gbit/s digital Laser Module
with integrated electro-absorption Modulator
Description
This Alcatel 1916 LMM contains an Alcatel
DFB laser with monolithically integrated
electro-absorption modulator (ILM). This
chip provides much lower dispersion
penalties than a directly modulated DFB,
without the complexity of LiNbO3 external
modulators. The Alcatel 1916 LMM is
optimized for ultra long-haul transmission
systems using non-dispersion shifted and
optical fiber amplifiers.
