3CN00347CE - Alcatel Optronics

Description

This laser module contains an Alcatel

SLMQW DFB laser with 25 Ω

impedance matching designed for use

in Wavelength Division Multiplexed

(WDM) systems, h ig h power direc t

modulation operations up to

2.5 Gbit/s. The module incorporates a

therm oelectr i c c ooler, p r ecision

thermistor, and optical isolator for

stable operation under all conditions.

Features

• Up to 10 mW output power

• Low dispersion penalt y

• Optimized for direct modulation at

2.5 Gbit/s

• Wavelength selection according to

ITU-T G.692

• 50 GHz spacing available

• Internal optical isolator

• 25 Ω RF impedance matching and

DC bias RF filtering

• Industry - standard hermetic 14-pin

butterfly package

• InGaAsP Distributed FeedBack

SLMQW (DFB) laser

Applications

• EDFA - free lon g span STM-16 an d

OC-48 DWDM transmission syst em s

• High-speed DWDM Metropolitan

Area Networks

• Saturation Laser for WDM EDFA

• Instrumentation.
