Erbium Doped Fiber Amplifier Edfa

The erbium doped fiber amplifier edfa is the most deployed fiber amplifier as its amplification window coincides with the third transmission window of silica based optical fiber.

Edfa cw c0 mr 18 18 fca 1530 1565nm c band single channel rs 232 uart 5 vdc. Edfa erbium doped fiber amplifier is an optical device used to compensate optical signal attenuation caused by fibers and components to increase optical transmission distance. Erbium doped fiber amplifiers. Invented in 1987 edfa is now most commonly used to compensate the loss of an optical fiber in long distance optical communication.

Model output power dbm gain db dimension mm datasheet. They are enclosed in a compact turnkey benchtop package with fc apc input and output connectors. Erbium doped fiber amplifiers are the by far most important fiber amplifiers in the context of long range optical fiber communications. Thorlabs core pumped erbium doped fiber amplifiers edfas offer 20 dbm 100 mw output power with a low noise figure of 5 db.

They can efficiently amplify light in the 1 5 μm wavelength region where telecom fibers have their loss minimum. 90 x 70 x 15.
