Kedu ihe bụ EDFA Amplifier

EDFA (Erbium-doped Fiber Amplifier), nke e bu ụzọ mepụta na 1987 maka iji azụmaahịa, bụ ihe nrịbama ngwa anya kacha arụ ọrụ na sistemụ DWDM nke na-eji eriri Erbium-doped dị ka ihe nkwalite ngwa anya iji welie akara ngosi. Ọ na-eme ka mmụba ozugbo maka akara nwere ọtụtụ wavelengths, nke bụ isi n'ime eriri abụọ. Otu bụ Conventional, ma ọ bụ C-band, ihe dị ka site na 1525 nm ruo 1565 nm, nke ọzọ bụ ogologo, ma ọ bụ L-band, ihe dịka 1570 nm ruo 1610 nm. Ka ọ dị ugbu a, ọ nwere eriri mgbapụta abụọ a na-ejikarị, 980 nm na 1480 nm. The 980nm band nwere akụkụ absorption dị elu nke a na-ejikarị na ngwa mkpọtụ dị ala, ebe band 1480nm nwere akụkụ nke ntanye dị ala mana nke sara mbara nke a na-ejikarị eme ihe maka ụda ike dị elu.

Ọgụgụ na-esonụ na-akọwa n'ụzọ zuru ezu ka EDFA amplifier si eme ka mgbama dị elu. Mgbe EDFA amplifier na-arụ ọrụ, ọ na-enye laser mgbapụta nwere 980 nm ma ọ bụ 1480 nm. Ozugbo laser mgbapụta na ntinye ntinye na-agafe na njikọ njikọ ahụ, a ga-agbanye ha n'elu eriri Erbium-doped. Site na mmekorita ya na ion doping, enwere ike nweta nkwalite mgbaàmà n'ikpeazụ. Nke a niile-optical amplifier ọ bụghị nanị na-ewetu ọnụ ahịa ahụ nke ukwuu mana ọ na-eme ka ọ dị mma maka nkwalite mgbama ngwa anya. Na nkenke, EDFA amplifier bụ ihe dị ịrịba ama na akụkọ ihe mere eme nke fiber optics nke nwere ike ịkwalite akara ozugbo na ọtụtụ wavelengths karịa otu eriri, kama ịgbasa mgbaama ngwa anya-electrical-optical.
