(ML9xx43) 2.5Gbps InGaAsP DFB LASER DIODE
MITSUBISHI LASER DIODES

ML9XX43 SERIES
Notice : Some parametric limits are subject to change 2.5Gbps InGaAsP DFB LASER DIODE

TYPE NAME
DESCRIPTION

ML925B43F / ML920J43S ML925J43F / ML920L43S
APPLICATION
2.5Gbps long-haul transmission

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.

FEATURES
· Wide temperature range operation (-20oC to 95oC) · High side-mode-suppression-ratio (typical 40dB) · High resonance frequency (typical 11GHz)
