Erbium Doped Fiber Amplifier Edfa

Erbium doped fiber amplifiers.

Erbium doped fiber amplifier edfa.

Erbium doped fiber amplifier edfa is an optical amplifier used in the c band and l band where loss of telecom optical fibers becomes lowest in the entire optical telecommunication wavelength bands. Erbium doped fiber amplifiers are the by far most important fiber amplifiers in the context of long range optical fiber communications. Model output power dbm gain db dimension mm datasheet.

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. They can efficiently amplify light in the 1 5 μm wavelength region where telecom fibers have their loss minimum. Invented in 1987 edfa is now most commonly used to compensate the loss of an optical fiber in long distance optical communication. 90 x 70 x 15.
