Optical Amplifier EDFA for WDM System | Glsun
What's EDFA? Erbium-Doped Fiber Amplifier (EDFA) is an optical amplifier used in the C-band and L-band, where the loss of telecom optical fibers becomes lowest in the entire optical telecommunication wavelength bands. It is used in the telecommunications field and in various types of research fields. An EDFA is "doped" with a material called erbium. Optical amplifiers can directly amplify...
