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