MITSUBISHI LASER DIODES PRELIMINARY ML9XX17 SERIES Notice : This is not a final specification Some parametric limits are subject to change. InGaAsP MQW-DFB LASER DIODE WITH EA MODULATOR TYPE NAME ML9XX17 DESCRIPTION FEATURES ML9XX17 series are DFB (Distributed Feedback) laser diodes with a monolithcally integrated EA (Electro-Absorption) modulator emitting light beam at 1550nm. The laser is suitable to a light source for use in ultra-long-haul transmission over 700km. DFB laser diode integrated with EA (Electro-Absorption) modulator 2.5Gb/s long-haul transmission over 700km High side-mode-suppression-ratio (typical 40dB) High extinction ratio Optional wavelength in range of 1545nm to 1560nm is available APPLICATION 2.5Gb/s trunk-line systems ABSOLUTE MAXIMUM RATINGS Symbol Parameter Conditions Ratings Unit IF Laser forward current CW 200 mA VRL Laser reverse voltage - 2 V VEA Modulator voltage - 0 - -3 Tc Case temperature - + 15 - +35 deg.C Storage temperature - - 40 -+100 deg.C Tstg V ELECTRICAL/OPTICAL CHARACTERISTICS (Tc=25deg.C) Symbol Parameter Ith Thereshold current Iop Operation current Vop Wp Operating voltage Min.
