1,550nm MQW-DFB

DWDM Direct Modulation Laser

FLD5F6CX-E

FEATURES

• Direct Modulation MQW DFB Laser

• Built-in TEC, Thermistor and Monitor PD

• 14-Pin Butterfly Type Module

• Low Residual Chirp

• Optimized for 2.5 Gb/s Modulation Rates

• Selected wavelengths according to ITU-T grid available

APPLICATIONS

This MQW laser is intended for application in 2.5 Gb/s

long haul Dense Wavelength Division Multiplexing (DWDM) systems.

Transmission spans of 100 km are possible without amplification.

DESCRIPTION

The Multiple Quantum Well (MQW) Laser is a high power laser

capable of 2.5 Gb/s transmission. It is packaged in a “butterfly” type module.

The module employs a high efficiency optical coupling system, coupling the

laser output through a built-in optical isolator into a single mode fiber pigtail.

The modules also include a monitor photodiode, a thermoelectric cooler (TEC)

and thermistor. This device is designed for use in DWDM direct modulation transmission

systems. Selected wavelengths specified to the ITU-T grid are available.
