1 / 2 page  MITSUBISHI LASER DIODES ML9XX43 SERIES Notice : Some parametric limits are subject to change 2.5Gbps InGaAsP DFB LASER DIODE Aug. 2005 MITSUBISHI ELECTRIC TYPE NAME DESCRIPTION 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. APPLICATION 2.5Gbps long-haul transmission FEATURES · Wide temperature range operation (-20 oC to 95oC) · High side-mode-suppression-ratio (typical 40dB) · High resonance frequency (typical 11GHz) ABSOLUTE MAXIMUM RATINGS Symbol Parameter Conditions Ratings Unit Po Output power CW 10 mW If Forward current (Laser diode) --- 150 mA VRL Reverse voltage (Laser diode) --- 2 V IFD Forward current (Photo diode) --- 2 mA VRD Reverse voltage (Photo diode) --- 20 V Tc Case temperature --- -20 to +95 ºC Tstg Storage temperature --- -40 to +100 ºC ELECTRICAL/OPTICAL CHARACTERISTICS (Tc=25ºC) Symbol Parameter Test conditions Min.
