Erbium Doped Fibre Amplifier (EDFA)
EDFA is an optical device that is used to boost the intensity of optical signals being carried through a fibre optic communications system. An optical fibre is doped with the rare earth element erbium so that the glass fibre can absorb light at one frequency and emit light at another frequency.
