Alcatel 1915 LMM 10 Gbit/s WDM digital Laser Module with integrated electro-absorption Modulator Description This Alcatel 1915 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 1915 LMM is optimized for 10 Gbit/s TDM transmission systems. Features * * 7-pin package with either GPO or K connector RF input Very low dispersion penalty over 80 Km for 10 Gbit/s operation * * * * * * InGaAsP monolithically integrated DFB laser and modulator chip High frequency RF connector package with 50 RF impedance Low drive voltage ( 2 Vpp) Internal optical isolator High power available Wavelength selection according to ITU-T G.692 Applications * * STM-64 and OC-192 intermediate and long reach WDM transmission systems Terminals for submarine WDM 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 (emitted-target) wavelength Laser chip temperature range for tunability Side mode suppression Cut off frequency RF return loss Dispersion penalty Tracking error Symb.
