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
