I-fiber pigtail ibhekisela kusixhumi esifana ne-half jumper esetshenziselwa ukuxhuma i-fiber optical kanye ne-optical fiber coupler.Ihlanganisa isixhumi se-jumper kanye nesigaba se-fiber optical.Noma xhuma imishini yokudlulisa kanye nama-ODF racks, njll.
Ingxenye eyodwa kuphela ye-pigtail ye-fiber optical iyisixhumi esinyakazayo.Uhlobo lwesixhumi yi-LC/UPC, SC/UPC, FC/UPC, ST/UPC, LC/APC, SC/APC, FC/APC.Zombili iziphetho ze-jumper ziyizixhumi ezihambayo.Kunezinhlobo eziningi ze-interfaces, futhi ukuxhumana okuhlukile kudinga ama-couplers ahlukene.I-jumper ihlukaniswe kabili futhi ingasetshenziswa njenge-pigtail.
I-diameter eyinhloko ye-multimode fiber ingu-50-62.5μm, ububanzi obungaphandle be-cladding ngu-125μm, ububanzi obuyingqikithi ye-fiber yemodi eyodwa ngu-8.3μm, kanti ububanzi obungaphandle bokuvala buyi-125μm.Ubude begagasi obusebenzayo be-fiber optical bunobude obufushane obungu-0.85μm, ubude begagasi bude buyi-1.31μm no-1.55μm.Ukulahleka kwefayibha ngokuvamile kuncipha ngokwandiswa kwe-wavelength.Ukulahlekelwa ngu-0.85μm ngu-2.5dB/km, ukulahlekelwa ngu-1.31μm ngu-0.35dB/km, kanti ukulahlekelwa ngu-1.55μm ngu-0.20dB/km.Lokhu ukulahlekelwa okuphansi kakhulu kwefayibha, ene-wavelength engu-1.65 Ukulahlekelwa okungaphezulu kwe-μm kuvame ukwanda.Ngenxa yokumuncwa kwe-OHˉ, kukhona iziqongo zokulahlekelwa kububanzi obungu-0.90~1.30μm no-1.34~1.52μm, futhi lobu bubanzi bubili abusetshenziswa ngokugcwele.Kusukela ngawo-1980, imicu yemodi eyodwa ijwayele ukusetshenziswa kaningi, kanti ubude begagasi ende obungu-1.31μm busetshenziswe kuqala.
I-Multimode fiber
I-Multi Mode Fiber:Umongo wengilazi omaphakathi mkhulu (50 noma 62.5μm), ongadlulisa izindlela eziningi zokukhanya.Kodwa-ke, ukuhlakazeka kwe-inter-mode kukhulu uma kuqhathaniswa, okukhawulela imvamisa yokudluliselwa kwamasignali edijithali, futhi kuba kubi kakhulu ngokwanda kwebanga.Isibonelo: i-600MB/KM i-optical fiber inomkhawulokudonsa ongu-300MB kuphela ku-2KM.Ngakho-ke, ibanga lokudlulisela le-multimode fiber lifushane, ngokuvamile lingamakhilomitha ambalwa kuphela.
I-Single Mode Fiber
I-Single Mode Fiber:Umongo wengilazi omaphakathi mncane kakhulu (ububanzi bomnyombo ngokuvamile bungu-9 noma 10 μm) futhi ungadlulisa imodi eyodwa yokukhanya.Ngakho-ke, ukuhlakazeka kwayo kwe-inter-mode kuncane kakhulu, okufanele ukuxhumana okude, kodwa kukhona ukuhlakazeka kwezinto ezibonakalayo kanye nokuhlakazeka kwe-waveguide.Ngale ndlela, imicu yemodi eyodwa inezidingo eziphakeme zobubanzi be-spectral nokuzinza komthombo wokukhanya, okungukuthi, ububanzi be-spectral kufanele bube buncane futhi buzinze.Okungcono.Kamuva, kwatholakala ukuthi kubude begagasi obungu-1.31μm, ukuhlakazwa kwezinto ezibonakalayo kanye nokuhlakazwa kwe-waveguide ye-fiber yemodi eyodwa kukhona okuhle futhi okungalungile, futhi ubukhulu bufana ncamashi.Lokhu kusho ukuthi kubude begagasi obungu-1.31μm, ukuhlakazwa okuphelele kwefayibha yemodi eyodwa kunguziro.Ngokombono wezimpawu zokulahlekelwa kwe-fiber optical, i-1.31μm imane nje iyifasitela eliphansi lokulahlekelwa kwe-fiber optical.Ngale ndlela, isifunda se-wavelength esingu-1.31μm sesiphenduke iwindi elisebenza kahle kakhulu lokuxhumana nge-fiber optical, futhi liphinde libe ibhande eliyinhloko elisebenzayo lesistimu yokuxhumana ye-optical fiber yamanje.Imingcele eyinhloko ye-1.31μm ye-fiber yemodi eyodwa evamile inqunywa yi-International Telecommunication Union ITU-T esincomweni se-G652, ngakho le fiber ibizwa nangokuthi i-G652 fiber.
I-fiber yemodi eyodwa, ububanzi obuyisisekelo buncane kakhulu (8-10μm), isignali ye-optical idluliswa kuphela nge-engeli eyodwa exazululekayo nge-fiber axis, futhi idluliselwa kuphela ngemodi eyodwa, egwema ukuhlakazeka kwe-modal futhi yenza igumbi lokudlulisela. ububanzi bomkhawulokudonsa.Umthamo wokudlulisa mkhulu, ukulahlekelwa kwesignali ye-optical kuncane, futhi ukuhlakazeka kuncane, okulungele ukukhulumisana okukhulu nokude.
I-Multi-mode fiber, isignali ye-optical kanye ne-fiber axis idluliselwa kuma-engeli amaningi axazululekayo, futhi ukudluliswa kokukhanya okuningi kudluliselwa ngezindlela eziningi ngesikhathi esisodwa.Ububanzi bungu-50-200μm, obungaphansi kokusebenza kokudlulisela kwe-fiber yemodi eyodwa.Ingahlukaniswa nge-multimode fiber abrupt kanye ne-multimode graded fiber.Eyangaphambili inomgogodla omkhulu, izindlela zokudlulisa ezengeziwe, umkhawulokudonsa omncane, namandla amancane okudlulisela.
I-RAISEFIBER igxile ekukhiqizeni izintambo ze-optical patch kanye ne-pigtails, futhi inikeza imikhiqizo ye-fiber optic yochwepheshe kumakhasimende anezintambo ezihlanganisiwe.
