FOL1425Rxy / 1480nm High Efficiency Module
Date May.18.2005 ODC-2C002D
1480nm Pump LDM up to 400mW
Applications
• Pump Source for Er-Doped Fiber Amplifier
! C- and/or L-Band EDFA
! DWDM Amp
• Pump Source for Raman Amplifier
Description
• The FOL1425R 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.
• Newly developed thermal design enables the output power up to 400mW in the
conventional 14 pin butterfly package.
• A 2-lens-system couples a round shape light from the laser chip efficiently to the fiber.
• This laser module complies with telecom requirements described in Telcordia
TM
GR-468
requirement in the module.
Features
• Rated output power up to 400 mW (CW) with conventional 14 pin butterfly package
• 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, PM fiber only)
• Epoxy free design inside the module for long term Reliability
