Alcatel 1916 LMM 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 * Industry-standard 14-pin butterfly package * * * * * Very low dispersion penalty over 750km for 2.5 Gbit/s operation InGaAsP monolithically integrated DFB laser and modulator chip High frequency butterfly package with 50 RF impedance matching and DC bias RF filtering Low drive voltage ( 2 Vpp) Internal optical isolator High power available Applications * * STM-16 and OC-48 ultra long-haul transmission systems Terminals for submarine transmission systems Optical characteristics Parameter Threshold current Operating current Optical output power Laser forward voltage Modulator bias voltage Modulator drive voltage Dynamic extinction ratio Emission wavelength Side mode suppression Cut off frequency RF return loss Dispersion penalty Tracking error Symb.
