ML9XX43 SERIES
2.5Gbps InGaAsP DFB LASER DIODE
TYPE ML925B43F / ML920J43S
NAME _{ML925J43F / ML920L43S}
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 -20^oC 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 95^oC)
· High side-mode-suppression-ratio (typical 40dB)
· High resonance frequency (typical 11GHz)
