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.
