1,550nm MQW-DFB
Continous Wave Laser
FLD5F6CX-H
FEATURES
• Continuous Wave (CW) MQW DFB Laser
• Built-in TEC, Thermistor and Monitor PD
• 14-Pin Butterfly Type Module
• 10mW Output Power
• Selected wavelengths according to ITU-T grid available
• Polarization preserving (PANDA) fiber
APPLICATIONS
This MQW laser is intended for use in 2.5 and 10 Gb/s long haul
DWDM transmission systems.
DESCRIPTION
The Multiple Quantum Well (MQW) Laser has high power CW operation.
It is packaged in a “butterfly” type module. This module has high
optical coupling efficiency through an optical isolator. This module also includes a monitor
photodiode, a thermoelectric cooler (TEC) and thermistor. This laser is designed for use with
external modulation components (such as LiNb0 modulators).

NOTE
This device is not available with an axis aligned connector.
The Fujitsu connector is attached only for the convenience of measuring the
extinction ratio at incoming inspection of the customer. A fusion splice is the
recommended method for connecting this laser to an external modulator.
