Edfa (Erbium-doped fiber fiik), da farko don amfani da kasuwanci, shine mafi yawan fiber na amplification don inganta sigina na gani kai tsaye. Yana ba da izinin fitowar kai tsaye don sigina tare da ɗakunan ruwa da yawa, m a cikin ƙungiyoyi biyu. One is the Conventional, or C-band, approximately from 1525 nm to 1565 nm, and the other is the Long, or L-band, approximately from 1570 nm to 1610 nm. A halin yanzu, yana da guda biyu da aka saba amfani da tsintsaye masu amfani, 980 nm da 1480 nm. Bandungiyar 980nm tana da babbar hanyar sha ta sha mafi girma yayin aikace-aikacen hayaniya, yayin da Band Band Band-Sands wanda aka yi amfani da shi sosai don mafi girman ƙarfin iko.
Adadin da ke gaba daya dakile yana nuna yadda Edfa amplifer ke inganta sigina. Lokacin da EDFA amplifier yana aiki, yana ba da wani famfo mai yawa tare da 980 nm ko 1480 nm. Da zarar an kashe famfunan da shigarwar da ke wucewa ta hanyar ma'aurata, za a manne da yawa a kan fiber erbium-droped fiber.
