1,550nm Continuous
Wave DFB Laser
FEATURES
• Continuous Wave (CW) Light Source for DWDM System
• Output Power: 10mW
• Available at C-band ITU-T Wavelengths between
1527.99 to 1562.05nm
• Built-in TEC, Thermistor, Monitor PIN PD and Optical Isolator

FLD5F6CX-H
APPLICATIONS
2.5 and 10 Gb/s Long Haul DWDM Transmission Systems
DESCRIPTION
The laser is for a high power (10mW) 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 -20 to 70°C.
