•

Optimized for use with LiNbO3 external

modulator

Polarization maintaining fiber pigtail

InGaAsP Distributed FeedBack SLMQW (DFB)

laser

This laser module contains an Alcatel

SLMQW DFB laser and is designed for use

with external modulation optimized for high

power Wavelength Division Multiplexed

(WDM) systems. The module incorporates a

polarization maintaining fiber pigtail,

thermoelectric cooler, precision thermistor,

and optical isolator for stable operation

under all conditions.
