Edition 1.1
July 2004

1,550nm Continuous
Wave DFB Laser

FEATURES

· Continuous Wave (CW) Light Source for DWDM System
· Output Power: 16dBm
· Available at C-band ITU-T Wavelengths between

1528.773 to 1569.594nm

· Built-in TEC, Thermistor, Monitor PIN PD and Optical Isolator
· Polarization maintaning (PANDA) fiber

APPLICATIONS

10 and 40 Gb/s long haul DWDM Transmission systems.

DESCRIPTION

The laser is for a high power (16dBm) CW operation, at selected C-band
ITU-T grid wavelengths. The module includes an optical isolator monitor photodiode, thermistor and a
thermo-electric cooler. This laser is designed for use with external modulation components (such as
LiNbO3 modulators). The device comes in "butterfly" type, 14-pin package, and operates
between 0 to 70°C.
