MITSUBISHI LASER DIODES ML9XX40 SERIES Notice : Some parametric limits are subject to change 2.5Gbps InGaAsP DFB LASER DIODE TYPE NAME DESCRIPTION ML925B40F / ML920J40S ML925J40F / ML920L40S APPLICATION · 2.5Gbps long-haul transmission · Coarse WDM application ML9XX40 series are uncooled DFB (Distributed Feedback) laser diodes for 2.5Gbps transmission emitting light beam at 1470~1610nm. λ/4 shifted grating structure is employed to obtain excellent SMSR performance under 2.5Gbps modulation. Furthermore, ML9xx40 can operate in the wide temperature range from 0oC to 85 oC without any temperature control. They are well suited for light source in long distance digital transmission application of coarse WDM. FEATURES · λ/4 shifted grating structure · Wide temperature range operation (0oC to 85oC) · High side-mode-suppression-ratio (typical 45dB) · 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) Case temperature Storage temperature Conditions CW ------------Ratings 6 150 2 2 20 0 to +85 -40 to +100 Unit mW mA V mA V ºC ºC ELECTRICAL/OPTICAL CHARACTERISTICS (Tc=25ºC) Symbol Ith Parameter Threshold current Test conditions CW CW Tc=85ºC CW, Po=5mW CW, Po=5mW Tc=85ºC CW, Po=5mW CW, Po=5mW CW, Po=5mW CW, Po=5mW CW, Po=5mW, Tc=0 to 85ºC 2.48832Gbps,Ib=Ith, Ipp=40mA CW, Po=5mW CW, Po=5mW 2.48832Gbps,Ib=Ith, Ipp=40mA 2.48832Gbps,Ib=Ith, Ipp=40mA 20%-80% CW, Po=5mW,VRD=1V,RL=10Ω VRD=5V VRD=5V Min.
