Ibanga lokudlulisela le-fiber yemodi eyodwa: Ukudluliswa kwesiteshi esingu-64 se-40G Ethernet kungaba ubude obungamamayela angu-2,840 kukhebula yemodi eyodwa. I-fibre yemodi eyodwa ngokuyinhloko yakhiwe indikimba, isendlalelo esibambekayo kanye nongqimba olunamathelayo.Umongo wenziwe ngezinto ezibonisa ngale.I-cladding inenkomba ye-refractive encane kancane kunomongo, okuholela kumphumela we-optical waveguide ovumela iningi. of the field electromagnetic to be trapped in the core.I-coating izenzo zokuvikela I-fiber ivikelwe kumswakama kanye nokuhuzuka komshini, kuyilapho ikhulisa ukuguquguquka kwe-fiber. Ngaphandle kwesendlalelo sokumboza, ijazi lepulasitiki livame ukungezwa.
Uyini umehluko phakathi kwefayibha yemodi eyodwa ne-multimode fiber?
Umehluko kunkomba ye-refractive: Imicu yemodi eyodwa isebenzisa iphrofayili yenkomba yesinyathelo. Imicu ye-Multimode ingasebenzisa amaphrofayili e-inkomba yesinyathelo noma amaphrofayili enkomba esezingeni.Ngakho-ke, imicu ye-quartz ingaphinda isebenzise imicu ye-multimode ye-index yesinyathelo, imicu ye-index ye-multimode graded, kanye nemicu ye-index yesinyathelo esisodwa. Izinhlobo ezintathu.
Umehluko kumodi yokudlulisela: i-fiber yemodi eyodwa ingadlulisela imodi eyodwa kuphela kubude begagasi obunikeziwe bokusebenza, futhi i-multimode fiber ingadlulisela izindlela ezimbalwa.Ukusabalala kwamagagasi kagesi ku-fiber optical kungowe-waveguide eyindilinga eyindilinga.Lapho ukukhanya kukhanya kubonakala ngokuphelele esibonakalayo sendawo ephakathi nendawo, igagasi kazibuthe kagesi livalelwe phakathi nendawo, okubizwa ngegagasi eliqondisiwe noma imodi eqondisiwe. Ngegagasi eliqondisiwe elinikeziwe kanye nobude begagasi obusebenzayo, kunezimo ezihlukahlukene zesigameko ezenelisa izimo zokubonakala okuphelele, okubizwa ngokuthi izindlela ezihlukene zamagagasi aqondisiwe. Ihlukaniswe yaba i-multimode fiber kanye ne-fibre yemodi eyodwa kumodi yokudlulisela.
Umehluko ebangeni lokudlulisela: ibanga lokudlulisela kanye nomkhawulokudonsa wokudlulisela we-fiber yemodi eyodwa ngokusobala kungenxa ye-multimode fiber. Uma ibanga lokudlulisela likhulu kuno-5 km, isignali yedatha yebhendi enkulu idluliselwa isikhathi eside ukuze kukhethwe i-fiber yemodi eyodwa. Uma ibanga lokudlulisela lingamakhilomitha ambalwa, imodi eminingi iyisinqumo esingcono kakhulu ngoba i-LED isihambisi/umamukeli sidinga ukukhanya kwe-laser kunemodi eyodwa. Kushibhe kakhulu.
Umehluko kubude begagasi bokudluliswa kwefayibha: i-fiber yemodi eyodwa inobubanzi obuncane bomgogodla futhi ingadluliselwa kuphela ngemodi eyodwa kubude obunikeziwe bokusebenza, ngomkhawulokudonsa wokudlulisela kanye nomthamo omkhulu wokudlulisela. I-Multimode fiber iyifayibha ebonakalayo engadlulisa ngesikhathi esisodwa kumamodi amaningi kubude obunikeziwe bokusebenza. Ifayibha ye-Multimode inomsebenzi wokudlulisa ompofu kunefiber yemodi eyodwa.
