EDFA (Erbium-doped Fiber Amplifier), e qapiloeng ka lekhetlo la pele ka 1987 bakeng sa tšebeliso ea khoebo, ke eona e sebelisoang ka ho fetisisa ea optical amplifier tsamaisong ea DWDM e sebelisang fiber ea Erbium-doped e le optical amplification medium ho ntlafatsa ka ho toba lipontšo. E thusa ho holisa hang-hang bakeng sa matšoao a nang le maqhubu a mangata a mangata, ha e le hantle ka har'a lihlopha tse peli. E 'ngoe ke ea "Conventional", kapa C-band, hoo e ka bang ho tloha ho 1525 nm ho ea ho 1565 nm, 'me e' ngoe ke Long, kapa L-band, e ka bang ho tloha 1570 nm ho ea 1610 nm. Ho sa le joalo, e na le lihlopha tse peli tse sebelisoang hangata, 980 nm le 1480 nm. Sehlopha sa 980nm se na le karolo e holimo ea ho monya hangata e sebelisoang ts'ebelisong ea lerata le tlase, athe sehlopha sa 1480nm se na le karolo e tlase empa e pharalletseng ea ho monya eo hangata e sebelisetsoang liamplifi tsa matla a holimo.
Setšoantšo se latelang se bontša ka ho hlaka kamoo amplifier ea EDFA e ntlafatsang lipontšo kateng. Ha EDFA amplifier e sebetsa, e fana ka laser ea pompo e nang le 980 nm kapa 1480 nm. Hang ha laser ea pompo le lipontšo tsa ho kenya li feta har'a coupler, li tla atisa ho feta fiber ea Erbium-doped. Ka ho sebelisana le li-ion tsa doping, ho phahamisa lets'oao ho ka finyelloa qetellong. Amplifier ena ea all-optical ha e theole litšenyehelo haholo feela empa e ntlafatsa haholo ts'ebetso ea ho holisa lets'oao la optical. Ka bokhutšoanyane, amplifier ea EDFA ke ketsahalo ea bohlokoa historing ea fiber optics e ka matlafatsang ka ho toba lipontšo tse nang le maqhubu a mangata holim'a fiber e le 'ngoe, ho e-na le ho phahamisa lets'oao la optical-electrical-optical signal.
