Alcatel 1905 LMI

Up to 20 mW WDM L-band version for external modulation

CW 1.55 µm Laser Module with optical Isolator

Description

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.
