Menene Amplifier EDFA

EDFA (Erbium-doped Fiber Amplifier), wanda aka fara ƙirƙira a cikin 1987 don amfani da kasuwanci, shine mafi girman ƙarar firikwensin gani a cikin tsarin DWDM wanda ke amfani da fiber na Erbium-doped azaman matsakaicin haɓakawa na gani don haɓaka sigina kai tsaye. Yana ba da damar haɓakawa nan take don sigina tare da tsayin raƙuman raƙuman ruwa da yawa, asali a tsakanin makada biyu. Daya shine Conventional, ko C-band, kusan daga 1525 nm zuwa 1565 nm, ɗayan kuma shine Dogon, ko L-band, kusan daga 1570 nm zuwa 1610 nm. A halin yanzu, yana da nau'ikan famfo guda biyu da aka saba amfani da su, 980 nm da 1480 nm. Ƙungiyar 980nm tana da mafi girman ɓangaren giciye wanda aka saba amfani da shi a cikin ƙaramar ƙaramar ƙararrawa, yayin da 1480nm band yana da ƙananan yanki amma mafi fa'ida na shaye-shaye wanda ake amfani da shi gabaɗaya don haɓaka ƙarfin ƙarfi.

Hoto mai zuwa yana kwatanta dalla-dalla yadda amplifier EDFA ke haɓaka sigina. Lokacin da amplifier na EDFA ke aiki, yana ba da laser famfo mai 980 nm ko 1480 nm. Da zarar famfo Laser da shigar siginar wucewa ta cikin ma'aurata, za a multixed a kan Erbium-doped fiber. Ta hanyar hulɗa tare da ions doping, ana iya samun haɓakar siginar a ƙarshe. Wannan duka-na gani amplifier ba kawai rage tsada sosai ba amma sosai inganta yadda ya dace don inganta siginar gani. A takaice, EDFA amplifier wani ci gaba ne a cikin tarihin fiber optics wanda zai iya haɓaka sigina kai tsaye tare da tsawon raƙuman ruwa sama da fiber ɗaya, maimakon haɓaka siginar gani-lantarki-na gani.
