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. Features * * * * * * * Wavelength selection according to ITU-T G.692 Industry-standard 14-pin butterfly package High frequency butterfly package with 50 RF impedance Low drive voltage ( 2 Vpp) InGaAsP monolithically integrated DFB laser and modulator chip Internal optical isolator Applications * * * STM-16 and OC-48 ultra long-haul transmission systems Terminals for submarine transmission systems Digital WDM CATV transmission Very low dispersion penalty over 750 km of fiber for 2.5 Gbit/s operation Optical characteristics Parameter Threshold current Operating current Optical output power Laser forward voltage Emission wavelength (emitted-target) wavelength Laser chip temperature range for tunability Modulator bias voltage Modulator drive voltage Dynamic extinction ratio Side mode suppression Cut off frequency RF return loss Dispersion penalty Tracking error Symb.
