Ibisobanuro: Erbium-Dope fibre AmplifierEDFA Amashanyarazi meza

Erbium-yuzuye optique fibre amplifier (EDFA, ni ukuvuga, optique ya signal optique hamwe na Er3 + ikozwe muri fibre ya fibre ikoresheje ikimenyetso) niyambere ya amplifier optique yakozwe na kaminuza ya Southampton mumwaka wa 1985, kandi nikimwe mubintu bikomeye byavumbuwe mumatumanaho ya fibre optique. Erbium-Dope fibre ni ubwoko bwa fibre hamwe nubutaka buke bwibintu bidasanzwe byisi erbium (Er) ion muri fibre ya quartz, niyo nkingi yaErbium-yuzuye fibre amplifier. Kuva mu mpera z'imyaka ya za 1980, intambwe nini yatewe mu bushakashatsi bwakozwe na erbium-dope fibre amplifier. Ikoranabuhanga rya WDM ryongereye cyane ubushobozi bwitumanaho rya fibre optique. Nibikoreshwa cyane optique amplifier mugutumanaho kwa fibre optique.

Gushyira mu bikorwa: Optical fibre amplifier nigikoresho cya optique cyongera ibikoresho byongera ibimenyetso bya optique muri sisitemu yitumanaho rya fibre optique. Muri sisitemu yitumanaho ukoresheje fibre optique, ni tekinoroji yongerera mu buryo butaziguye ibimenyetso bya optique idahinduye ibimenyetso bya optique mubimenyetso byamashanyarazi. Erbium-dope fibre amplifier (EDFA Optical Amplifier, ni ukuvuga, amplificateur signal optique hamwe na erbium ion Er3 + muri fibre fibre ikoresheje ikimenyetso) niyo amplifier ya mbere ya optique yakozwe na kaminuza ya Southampton mu Bwongereza na kaminuza ya Tohoku yo mu Buyapani, ni kimwe mu bintu byavumbuwe mu itumanaho rya fibre optique. Erbium-Dope fibre ni ubwoko bwa fibre hamwe nubutaka buke bwibintu bidasanzwe byisi erbium (Er) ion muri fibre ya quartz, ikaba intandaro ya fibre amplifier ya Erbium. Kuva mu mpera z'imyaka ya za 1980, intambwe nini yatewe mu bushakashatsi bwakozwe na erbium-dope fibre amplifier. Ikoranabuhanga rya WDM ryongereye cyane ubushobozi bwitumanaho rya fibre optique. Nibikoreshwa cyane optique amplifier mugutumanaho kwa fibre optique.

Ijambo rifitanye isano:Amashanyarazi meza

Fibre ya Quartz yuzuye hamwe nibintu bidasanzwe byisi (nka Nd, Er, Pr, Tm, nibindi) birashobora gukora sisitemu yo murwego rwa lazeri nyinshi, kandi ikongerera mu buryo butaziguye urumuri rwinjiza rwinjira munsi yumucyo wa pompe. Nyuma yo gutanga ibitekerezo bikwiye, fibre laser irashirwaho. Uburebure bwumurongo wa ND-dope fibre amplifier ni 1060nm na 1330nm, ariko iterambere ryayo nogukoresha ni bike kubera gutandukana nicyambu cyiza cyitumanaho rya fibre nizindi mpamvu. Uburebure bwumurongo wa EDFA na PDFA buri mubihombo bike (1550nm) hamwe na zeru ikwirakwiza zero (1300nm) idirishya ryitumanaho rya fibre optique, kandi TDFA ikora muri S-band, ikwiranye cyane na sisitemu yo gutumanaho ya fibre optique. Cyane cyane EDFA, iterambere ryihuse, ryabaye ingirakamaro.

Hashingiwe kumajyambere ya erbium-dope fibre, fibre fibre nyinshi nshya ikomeza kugaragara. Kurugero, dual-band fibre amplifier (DBFA) ishingiye kuri fibre ya erbium-doped fibre ni Broadband optique amplifier, kandi umurongo mugari urashobora gukwirakwiza hafi yumurongo wose wigice cyinshi (WDM). Igicuruzwa gisa na ultra-wideband optique amplifier (UWOA), ifite umurongo mugari wo gukwirakwiza imiyoboro igera kuri 100 yumurongo wa fibre imwe.

Gushyira mu bikorwa

Ikoreshwa rya Erbium-Dope fibre amplifier (EDFA Amplifier) ​​muri sisitemu isanzwe ya optique ya fibre fibre sisitemu yo gutumanaho irashobora kuzigama ibintu byinshi byisubiramo, kandi intera ya relay iriyongera cyane, bifite akamaro kanini kuri sisitemu ndende ya kabili.

Porogaramu nyamukuru zirimo:

1, irashobora gukoreshwa nkurumuri rurerure rwongera imbaraga. Gakondo ya elegitoroniki fibre optique Gusubiramo bifite aho bigarukira. Kurugero, mugihe ibimenyetso bya digitale nibimenyetso bisa bihinduwe hamwe, gusubiramo bigomba guhinduka bikurikije; Iyo ibikoresho bihindutse kuva kumuvuduko muke kugera kumuvuduko mwinshi, repetater igomba gusimburwa uko bikwiye. Gusa wohereze uburebure bumwe bwikimenyetso cyumucyo, kandi imiterere iragoye, ihenze, nibindi. Erbium-dope fibre amplifiers yatsinze izo nenge, ntizigomba gusa guhinduka hamwe nuburyo bwo guhindura ibimenyetso, ariko kandi ntizikeneye gusimburwa mugihe ibikoresho byaguwe cyangwa bigakoreshwa muburyo bwo guhuza ibice bya optique.

2, irashobora gukoreshwa nka optique ya transmitter post amplifier hamwe na optique yakira preamplifier. Nka post amplifier ya optique yohereza, imbaraga zo kohereza laser zirashobora kwiyongera kuva 0db kugeza kuri + 10db. Iyo ikoreshejwe nka preamplifier ya optique yakira, ibyiyumvo byayo nabyo birashobora kunozwa cyane. Kubwibyo, 1-2 erbium-dope amplifier yashyizweho kumurongo, kandi intera yohereza ibimenyetso irashobora kwiyongera 100km.

Mubyongeyeho, erbium-dope fibre amplifier (EDFA Amplifier) gukemura ikibazo. Ibyiza bidasanzwe bya Erbium-Dope fibre amplifier byamenyekanye nisi, kandi byarakoreshejwe cyane. Nyamara, Erbium-Dope fibre amplifier nayo ifite aho igarukira. Kurugero, mubitumanaho birebire ntibishobora kuba hejuru no hepfo, guhuza ibikorwa bya sitasiyo biragoye cyane, ntibyoroshye kubona amakosa, pompe yumucyo utanga ubuzima ntabwo ari ndende, hamwe niterambere rikomeje ryiterambere rya tekinoroji ya fibre optique, ibyo bibazo bizakemuka neza.
