Menene Amplifier EDFA

EDFA (Erbium-doped Fiber Amplifier), wanda aka fara ƙirƙira a shekarar 1987 don amfanin kasuwanci, shine mafi girman na'urar ƙara haske a cikin tsarin DWDM wanda ke amfani da zare mai ɗauke da Erbium a matsayin hanyar ƙara haske ta gani don haɓaka sigina kai tsaye. Yana ba da damar ƙara haske nan take ga sigina masu tsawon rai da yawa, galibi a cikin madaukai biyu. Ɗaya shine na al'ada, ko C-band, kusan daga 1525 nm zuwa 1565 nm, ɗayan kuma shine Long, ko L-band, kusan daga 1570 nm zuwa 1610 nm. A halin yanzu, yana da madaukai biyu da ake amfani da su akai-akai, 980 nm da 1480 nm. Madaukai na 980nm yana da mafi girman sashin ɗaukar haske wanda yawanci ana amfani da shi a aikace-aikacen ƙananan amo, yayin da madaukai na 1480nm yana da ƙaramin ɓangaren ɗaukar haske amma mai faɗi wanda galibi ana amfani da shi don manyan amplifiers.

Wannan adadi mai zuwa ya nuna dalla-dalla yadda na'urar ƙara ƙarfin sigina ta EDFA ke ƙara ƙarfin sigina. Lokacin da na'urar ƙara ƙarfin sigina ta EDFA ke aiki, yana bayar da na'urar ƙara ƙarfin sigina mai ƙarfin 980 nm ko 1480 nm. Da zarar na'urar ƙara ƙarfin sigina ta famfo da siginar shigarwa sun ratsa ta cikin mahaɗin, za a haɗa su da yawa a kan zaren da aka yi wa Erbium. Ta hanyar hulɗa da ions ɗin ƙara ƙarfin sigina, za a iya cimma nasarar ƙara ƙarfin sigina a ƙarshe. Wannan na'urar ƙara ƙarfin sigina mai amfani da dukkan-na'urori ba wai kawai tana rage farashi ba, har ma tana inganta ingantaccen haɓaka ƙarfin sigina mai amfani da hasken. A takaice, na'urar ƙara ƙarfin sigina ta EDFA wani muhimmin ci gaba ne a tarihin na'urorin ƙara ƙarfin sigina waɗanda za su iya ƙara ƙarfin sigina kai tsaye tare da raƙuman ruwa da yawa a kan zare ɗaya, maimakon na'urar ƙara ƙarfin sigina mai amfani da hasken-lantarki-na'urori.
