Ibisobanuro: Amplifier ya fibre ivanze na ErbiumEDFA Optical Amplifier

Amplifier y'urusobe rw'amatara rwa Erbium (EDFA, ni ukuvuga amplifier y'ibimenyetso bya optique ifite Er3 + doped mu gice cy'imbere cya fibre binyuze muri icyo kimenyetso) ni yo amplifier ya mbere y'ibimenyetso yakozwe na Kaminuza ya Southampton mu 1985, kandi ni imwe mu mpinduka zikomeye mu itumanaho rya fibre ya optique. Fibre ya Erbium-doped ni ubwoko bwa fibre ifite ioni nke za element erbium (Er) muri fibre ya quartz, ikaba ari yo shingiro ryaAmplifier ya fibre ikoresheje ErbiumKuva mu mpera z'imyaka ya 1980, habayeho iterambere rikomeye mu bushakashatsi ku byuma bikuramo fibre bikozwe na erbium. Ikoranabuhanga rya WDM ryongereye cyane ubushobozi bw'itumanaho rya fibre optique. Niyo amplifier ikoreshwa cyane mu itumanaho rya fibre optique.

Ikoreshwa: Amplifier ya fibre optique ni igikoresho cy'ingufu zo kongera urumuri mu buryo butaziguye ikimenyetso cy'urumuri muri sisitemu y'itumanaho ya fibre optique. Muri sisitemu y'itumanaho ikoresha fibre optique, ni ikoranabuhanga ryongera urumuri mu buryo butaziguye ikimenyetso cy'urumuri hatabayeho guhindura ikimenyetso cy'urumuri mo ikimenyetso cy'amashanyarazi. Amplifier ya fibre optique ya Erbium (EDFA Optical Amplifier, ni ukuvuga amplifier ya optique ifite erbium ion Er3 + mu gice cy'imbere cya fibre binyuze mu kimenyetso) ni yo amplifier ya mbere y'urumuri yakozwe na Kaminuza ya Southampton mu Bwongereza na Kaminuza ya Tohoku yo mu Buyapani, ni kimwe mu bihangano bikomeye mu itumanaho rya fibre optique. Fibre optique ya Erbium ni ubwoko bwa fibre ifite ioni nke za element erbium (Er) muri fibre quartz, ikaba ari yo shingiro rya amplifier ya fibre optique ya Erbium. Kuva mu mpera za 1980, habayeho iterambere rikomeye mu bushakashatsi ku mashini zikoresha erbium. Ikoranabuhanga rya WDM ryongereye cyane ubushobozi bw'itumanaho rya fibre optique. Ni yo amplifier ya optique ikoreshwa cyane mu itumanaho rya fibre optique.

Ibipimo by'ibanze

Izina ry'ijambo: Erbium-doped fiber amplifier

Ijambo rifitanye isano:Amplifier y'urumuri

Fibre ya Quartz irimo ibintu by’ubutaka bidasanzwe (nka Nd, Er, Pr, Tm, nibindi) ishobora gukora sisitemu ya laser y’urwego rwinshi, kandi ikazamura urumuri rw’ikimenyetso cy’injira mu buryo butaziguye munsi y’urumuri rwa pompe. Nyuma yo gutanga ibitekerezo bikwiye, laser ya fiber irakorwa. Ubunini bw’uburebure bwa amplifier ya fiber ya ND ni 1060nm na 1330nm, ariko iterambere ryayo n’ikoreshwa ryayo ni bike bitewe no kunyura mu nzira nziza y’itumanaho rya fiber n’izindi mpamvu. Ubunini bw’uburebure bwa EDFA na PDFA buri mu gihombo gito cyane (1550nm) na zero dispersion wavelength (1300nm) mu itumanaho rya fiber ya optique, kandi TDFA ikora muri S-band, ikwiriye cyane porogaramu za sisitemu y’itumanaho rya fiber ya optique. Cyane cyane EDFA, iterambere ryihuse cyane, ryabaye ingirakamaro.

Hashingiwe ku iterambere rya fibre ikoresha erbium, hari izindi fibre amplifiers nshya nyinshi zikomeje kugaragara. Urugero, amplifier ya fibre ifite imigozi ibiri (DBFA) ishingiye kuri fibre ikoresha erbium ni amplifier ya optique ya broadband, kandi iyi broadband ishobora gukwira hafi ya bandwidth yose ya wavelength division multiplexing (WDM). Igicuruzwa nk'icyo ni amplifier ya optique ya ultra-wideband (UWOA), ifite bandwidth yo gukwirakwiza imiyoboro ya wavelength igera ku 100 muri fibre imwe.

Gushyira mu bikorwa mu buryo bufatika

Gukoresha amplifier ya fibre ya Erbium-doped (EDFA Amplifier) ​​muri sisitemu isanzwe y'itumanaho rya digitale ya optique fibre bishobora kurokora optique repeaters nyinshi, kandi intera yo gusimbuza irazamuka cyane, ibi bikaba ingenzi cyane kuri sisitemu yo gusimbuza insinga ikora kure.

Porogaramu zayo z'ingenzi zirimo:

1, ishobora gukoreshwa nk'imashini igabanya intera y'urumuri. Imashini zisanzwe zikoresha fibre optique zifite imbogamizi nyinshi. Urugero, iyo ikimenyetso cya digitale n'ikimenyetso cya analog bihinduriwe hamwe, imashini isubiramo igomba guhindurwa uko bikwiye; Iyo ibikoresho bihindutse kuva ku muvuduko muto kugera ku muvuduko wo hejuru, imashini isubiramo igomba gusimburwa uko bikwiye. Yohereza gusa uburebure bumwe bw'ikimenyetso cy'urumuri, kandi imiterere yayo iragoye, irahenze, n'ibindi. Imashini zikoresha fibre zo mu bwoko bwa Erbium zitsinda izi nzitizi, ntabwo zigomba guhinduka gusa iyo habayeho impinduka mu buryo bw'ikimenyetso, ahubwo kandi ntizigomba gusimburwa iyo ibikoresho byaguwe cyangwa bikoreshejwe mu gukwirakwiza uburebure bw'urumuri.

2, ishobora gukoreshwa nk'imashini itera optique transmitter post amplifier na optique receiver preamplifier. Nk'imashini itera optique post amplifier ya optique transmitter, imbaraga zo kohereza za laser zishobora kongerwa kuva kuri 0db kugeza kuri +10db. Iyo ikoreshejwe nk'imashini itera optique preamplifier, ubushobozi bwayo bushobora no kongerwa cyane. Kubwibyo, amplifier 1-2 za erbium-doped gusa nizo zishyirwaho ku murongo, kandi intera yo kohereza ikimenyetso ishobora kongerwaho 100-200km.

Byongeye kandi, amplifier ya fibre ikoresheje erbium (Akamplifier ya EDFA) gukemura ikibazo. Ibyiza byihariye bya amplifiers za fibre za Erbium byamenyekanye ku isi yose, kandi byagiye bikoreshwa cyane. Ariko, amplifiers za fibre za Erbium nazo zifite imbogamizi zimwe na zimwe. Urugero, mu itumanaho rya kure ntirishobora kuba hejuru no hasi, itumanaho rya sitasiyo rirushaho kugorana, ntabwo byoroshye kubona amakosa, ubuzima bw'imashini zitanga urumuri ntibura igihe kirekire, hamwe n'iterambere rihoraho ry'ikoranabuhanga ry'itumanaho rya fibre optique, ibi bibazo bizakemurwa neza.
