MITSUBISHI LASER DIODES ML9XX43 SERIES 2.5Gbps InGaAsP DFB LASER DIODE Notice : Some parametric limits are subject to change TYPE NAME ML925B43F / ML920J43S ML925J43F / ML920L43S DESCRIPTION APPLICATION ML9XX43 series are uncooled DFB (Distributed Feedback) laser diodes for 2.5Gbps transmission emitting light beam at 1550nm. ML9xx43 can operate in the wide temperature range from -20oC to 95 oC without any temperature control. They are well suited for light source in long distance digital transmission application. 2.5Gbps long-haul transmission FEATURES · Wide temperature range operation (-20oC to 95oC) · High side-mode-suppression-ratio (typical 40dB) · High resonance frequency (typical 11GHz) ABSOLUTE MAXIMUM RATINGS Symbol Po If VRL IFD VRD Tc Tstg Parameter Output power Forward current (Laser diode) Reverse voltage (Laser diode) Forward current (Photo diode) Reverse voltage (Photo diode) Conditions CW --------- Ratings 10 150 2 2 20 Unit mW mA V mA V Case temperature --- -20 to +95 Storage temperature --- -40 to +100 ºC ºC ELECTRICAL/OPTICAL CHARACTERISTICS (Tc=25ºC) Symbol Parameter Ith Threshold current Iop Operation current Vop η λp SMSR θ // θ┴ fr Operating voltage Slope efficiency Peak wavelength Side mode suppression ratio Beam divergence angle (parallel) <*1> (perpendicular) <*1> Resonance frequency Test conditions CW CW, Tc=95ºC CW, Po=5mW CW, Po=5mW , Tc=95ºC CW, Po=5mW CW, Po=5mW CW, Po=5mW, Tc=-20 to 95ºC CW, Po=5mW, Tc=-20 to 95ºC CW, Po=5mW Typ.
