I-fiber pigtail ibhekisela kwikhonkco efana ne-half jumper esetyenziselwa ukudibanisa i-fiber optical kunye ne-optical fiber coupler.Iquka i-jumper connector kunye necandelo le-fiber optical.Okanye udibanise izixhobo zokuhambisa kunye neeracks ze-ODF, njl.
Isiphelo esinye kuphela se-pigtail yefiber optical sisixhobo esishukumayo.Uhlobo lomnxibelelanisi yiLC/UPC, SC/UPC, FC/UPC, ST/UPC, LC/APC, SC/APC, FC/APC.Zombini iziphelo zejumper ziziqhagamshelo ezihambayo.Kukho iintlobo ezininzi zojongano, kwaye ujongano olwahlukileyo lufuna izibini ezahlukeneyo.Ijumpi yohlulwe kabini kwaye isenokusetyenziswa njenge pigtail.
I-diameter engundoqo yefiber ye-multimode yi-50-62.5μm, i-diameter yangaphandle ye-cladding yi-125μm, i-diameter engundoqo ye-fiber ye-single-mode yi-8.3μm, kunye ne-diameter yangaphandle ye-cladding yi-125μm.I-wavelength esebenzayo ye-fiber optical ine-wavelength emfutshane ye-0.85μm, ubude obude be-1.31μm kunye ne-1.55μm.Ilahleko yeFayibha ngokubanzi iyancipha ngobude bobude bobude.Ukulahlekelwa kwe-0.85μm ngu-2.5dB / km, ukulahlekelwa kwe-1.31μm ngu-0.35dB / km, kunye nokulahlekelwa kwe-1.55μm ngu-0.20dB / km.Le yilahleko ephantsi kakhulu yefiber, kunye ne-wavelength ye-1.65 Ilahleko engaphezulu kwe-μm ivame ukunyuka.Ngenxa yokufunxwa kwe-OHˉ, kukho iincopho zokulahleka kwimiba ye-0.90 ~ 1.30μm kunye ne-1.34 ~ 1.52μm, kwaye ezi zintlu zimbini azisetyenziswanga ngokupheleleyo.Ukususela kwi-1980, iifayili ze-single-mode zivame ukusetyenziswa rhoqo, kwaye ubude be-long-wavelength 1.31μm busetyenziswe kuqala.
I-Multimode fiber
IFayibha yeNdlela ezininzi:Undoqo weglasi ophakathi utyebile (50 okanye 62.5μm), onokuthi udlulise iindlela ezininzi zokukhanya.Nangona kunjalo, ukusasazwa kwe-inter-mode kukhulu kakhulu, nto leyo ethintela ukuphindaphinda kokuhanjiswa kwemiqondiso yedijithali, kwaye iba yingozi ngakumbi ngokunyuka komgama.Umzekelo: I-600MB / KM i-fiber optical ine-300MB kuphela i-bandwidth kwi-2KM.Ke ngoko, umgama wothumelo lwefayibha yemultimode mfutshane, ngokuqhelekileyo ziikhilomitha ezimbalwa kuphela.
IFayibha yeMode enye
IFayibha yeNdlela enye:Undoqo weglasi ombindini ubhityile kakhulu (i-diameter engundoqo ngokuqhelekileyo yi-9 okanye i-10 μm) kwaye inokuhambisa indlela enye yokukhanya.Ke ngoko, i-inter-mode dispersion incinci kakhulu, ilungele unxibelelwano olude, kodwa kukho ukusasazwa kwezinto kunye ne-waveguide dispersion.Ngale ndlela, iifiber zemowudi enye zineemfuno eziphezulu zobubanzi bembonakalo kunye nokuzinza komthombo wokukhanya, oko kukuthi, ububanzi be-spectral kufuneka bube buncinci kwaye buzinzile.Ngcono.Kamva, kwafunyaniswa ukuba kwi-wavelength ye-1.31μm, i-waveguide dispersion kunye ne-waveguide dispersion ye-fiber-mode eyodwa ilungile kwaye ingalunganga, kwaye ubukhulu bufana ncakasana.Oku kuthetha ukuba kwi-wavelength ye-1.31μm, i-dispersion iyonke ye-fiber ye-single-mode yi-zero.Ukusuka kwindawo yokujonga iimpawu zokulahleka kwefiber optical, i-1.31μm nje ilahleko ephantsi yefestile ye-fiber optical.Ngale ndlela, ummandla we-wavelength we-1.31μm uye waba yifestile efanelekileyo kakhulu yokusebenza kunxibelelwano lwefiber optical, kwaye ikwayeyona nto iphambili yokusebenza kwenkqubo yonxibelelwano yefiber optical yangoku.Iiparamitha eziphambili ze-1.31μm ze-fiber ye-mode eyodwa zichongwa yi-International Telecommunication Union ITU-T kwisincomo se-G652, ngoko le fiber ibizwa ngokuba yi-G652 fiber.
I-fiber yemodi enye, i-diameter engundoqo incinci kakhulu (i-8-10μm), isignali ye-optical idluliselwa kuphela kwi-angle enye yokusombulula kunye ne-fiber axis, kwaye idluliselwe kuphela kwimodi enye, ethintela ukusasazeka kwe-modal kwaye yenza igumbi lokuhambisa. bandwidth ebanzi.Umthamo wokudlulisa ukhulu, ukulahleka kwesignali ye-optical kuncinci, kwaye ukusabalalisa kuncinci, okufanelekileyo kumthamo omkhulu kunye nonxibelelwano olude.
I-Multi-mode fiber, i-optical signal kunye ne-fiber axis ihanjiswa kwii-angles ezininzi ezixazululekayo, kwaye ukuhanjiswa kokukhanya okuninzi kuhanjiswa ngeendlela ezininzi ngexesha elinye.I-diameter yi-50-200μm, engaphantsi kwintsebenzo yokudluliselwa kwefayibha enye.Inokwahlulwa ibe yifayibha ye-multimode ye-multimode kunye ne-multimode graded fiber.Eyangaphambili inondoqo omkhulu, iindlela zokuhambisa ngaphezulu, i-bandwidth emxinwa, kunye nomthamo omncinci wothumelo.
I-RAISEFIBER igxile ekuveliseni iintambo ze-optical patch kunye ne-pigtails, kwaye ibonelela ngeemveliso ze-fiber optic zobuchwephesha kubathengi abane-wiring edibeneyo.
