High power 1480 / 14xx-nm Pump Laser Diode Module
Applications
Pump Source for EDFA
C- and/or L-Band EDFA
Pump Source for Raman Amplifier
C-band
Product Type :
FOL1435 Series
Descriptions
The FOL1435 series has been designed for use in a wide variety of optical amplifier,
such as EDFA or Raman Amplifier used in optical transmission systems, especially in
dense wavelength-division-multiplexing (DWDM) systems.
A strained multi-quantum well laser diode chip is integrated with thermo-electric cooler
(TEC), thermistor and PIN photodiode in a hermetically sealed 14 pin butterfly package.
A 2-lens-system couples a round shape light from the laser chip efficiently to the fiber
and enables the output power up to 500 mW.
This laser module complies with telecom requirements described in Telcordia
TM
GR-
468 requirement and manufactured in an ISO
TM
9001 certified production line.
Features
Rated output power up to 500 mW (CW)
Widely deployed reliable package design with industry compatible 14 pin butterfly
footprint
Internal Thermo-electric cooler (TEC) and Thermistor for stable operation
Integrated PIN photodiode for back facet monitor
Internal optical Isolator (optional)
Single mode fiber and Polarization maintaining fiber pigtail
Wavelength stabilization available with external FBG (optional)
Epoxy free design inside the module for long term reliability
EU RoHS compliant
(Exemption 7b applied)
