| MITSUBISHI LASER DIODES PRELIMINARY Notice : This is not a final specification Some parametric limits are subject to change. ML9XX17 SERIES InGaAsP MQW-DFB LASER DIODE WITH EA MODULATOR TYPE NAME ML9XX17 FEATURES 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 DESCRIPTION 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.
