| PRELIMINARY Notice: This is not a final specification MITSUBISHI LASER DIODES ML7XX34 SERIES 2.5Gbps InGaAsP DFB LASER DIODE Notice : Some parametric limits are subject to change TYPE NAME DESCRIPTION ML725B34F / ML720J34S ML725J34F / ML720L34S APPLICATION 2.5Gbps transmission ML7XX34 series are uncooled DFB (Distributed Feedback) laser diodes for 2.5Gbps transmission emitting light beam at 1310nm. ML7XX34 can operate in the wide temperature range from -40oC to 95 oC without any temperature control. FEATURES * Wide temperature range operation (-40oC 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) Case temperature Storage temperature Conditions CW ------------Ratings 10 150 2 2 20 -40 to +95 -40 to +100 Unit mW mA V mA V C C ELECTRICAL/OPTICAL CHARACTERISTICS (Tc=25C) Symbol Ith Iop Vop p SMSR // fr tr,tf Parameter Threshold current Operation current Operating voltage Slope efficiency Peak wavelength Side mode suppression ratio Beam divergence angle (parallel) <*1> (perpendicular) <*1> Resonance frequency Rise and Fall time <*2> Test conditions CW CW, Tc=95C CW, Po=5mW CW, Po=5mW , Tc=95C CW, Po=5mW CW, Po=5mW CW, Po=5mW, Tc=-40 to 95C CW, Po=5mW, Tc=-40 to 95C CW, Po=5mW CW, Po=5mW 2.48832Gbps,Ib=Ith, Ipp=40mA Min. ----------0.30 1290 35 --------0.05 ----Typ.
