ML7XX34 SERIES

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

TYPE NAME

DESCRIPTION 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 -40o C to 95 o C without any temperature control. APPLICATION

2.5Gbps transmission

FEATURES

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