ML7XX34 SERIES
2.5Gbps InGaAsP DFB LASER DIODE

Notice : Some parametric limits are subject to change

TYPE NAME
DESCRIPTION

ML725B34F / ML720J34S ML725J34F / ML720L34S
APPLICATION
2.5Gbps transmission

ML7XX34 series are uncooled DFB (Distributed Feedback) laser diodes for 2.5Gbps transmission emitting light beam at 1310nm. ML7XX34 can operate in the wide temperature range from -40oC to 95 oC without any temperature control.

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