Umsebenzi oyinhloko wesixhumi se-fiber optic ukuxhuma ngokushesha imicu emibili ukuze isignali ye-optical iqhubeke nokwenza indlela ye-optical.Izixhumi ze-fiber optic zihamba, zisebenziseka kabusha, futhi ziyizingxenye ze-passive ezibaluleke kakhulu nezisetshenziswa kakhulu ezinhlelweni zokuxhumana ze-fiber optic.Izixhumi ze-fiber optic zivumela ubuso obubili bokuphela be-fiber ukuthi buhlanganiswe ngezinqe ngokunembile ukuze kwandiswe ukuhlangana kokuphuma kwamandla okukhanya. kusukela ku-fiber yokudlulisa kuya ku-fiber eyamukelayo, futhi imiphumela yesistimu ngenxa yokungenelela kwayo idinga ukuncishiswa.Ngenxa yokuthi ububanzi obungaphandle be-fiber buyi-125um kuphela, futhi ingxenye edlula ukukhanya incane, i-fiber yemodi eyodwa kuphela mayelana ne-9um, futhi i-multimode fiber ingu-50um no-62.5um, ngakho-ke ukuxhumana phakathi kwemicu kufanele kube ngokuqondile. kuqondaniswe.
Izingxenye eziyinhloko: i-ferrule
Ngendima yesixhumi se-fiber optic, kungabonakala ukuthi ingxenye ewumongo ethinta ukusebenza kwesixhumi i-ferrule.Izinga le-ferrule lithinta ngokuqondile ukunemba kwesikhungo sezintambo ezimbili.I-ferrule yenziwe nge-ceramic, insimbi noma ipulasitiki.I-Ceramic ferrule isetshenziswa kabanzi, into eyinhloko yi-zirconium dioxide, enezici zokuzinza okuhle kokushisa, ukuqina okuphezulu, indawo ephakeme yokuncibilika, ukumelana nokugqoka kanye nokunemba okuphezulu kokucubungula.Umkhono ungenye ingxenye ebalulekile yesixhumi, futhi umkhono usebenza njengokuqondanisa ukuze kube lula ukukhwezwa kwesixhumi.Ububanzi bangaphakathi bomkhono we-ceramic buncane kancane kunobubanzi obungaphandle be-ferrule, futhi umkhono osikiwe uqinisa ama-ferrules amabili ukuqondanisa okunembile.
Ukuze wenze ubuso bokugcina bemicu emibili buthintane kangcono, iziphetho ze-ferrule zivame ukugaywa zibe izakhiwo ezihlukene.I-PC, i-APC, ne-UPC imele uhlaka lwangaphambili lwesiphetho se-ceramic ferrule.I-PC iwukuthintana ngokomzimba, ukuthintana ngokomzimba.I-PC inobuso obuyindilinga obuncane obupholishiwe futhi bupholishiwe, ingaphezulu lembobo ligaywa libe indawo eyindilinga encane, kanti umnyombo we-optical fiber usendaweni ephakeme kakhulu lapho kugotshwa khona. ubuso obubili bokuphela kwefayibha buxhumene ngokomzimba.I-APC (I-Angled Physical Contact) ibizwa ngokuthi ukuxhumana okubonakalayo okugobile, futhi ubuso bokuphela kwefayibha buvamise ukugaywa bube yi-bevel engu-8°.I-engeli engu-8° yenza isiphetho sefayibha ubuso buqine futhi ibonise ukukhanya nge-engeli yayo e-beveled ukuya ku-cladding esikhundleni sokubuyela ngqo kumthombo, inikeze ukusebenza okungcono koxhumo.I-UPC (I-Ultra Physical Contact), i-super physical end face.UPC isekelwe ku-PC ukuze kuthuthukiswe ukupholishwa kobuso nokuphela kwendawo, ubuso bokuphela bubukeka bumise okwedome.Ukuxhunywa kwezixhumi kudinga ukuba kusakhiwo sobuso bokuphela okufanayo, isibonelo i-APC ne-UPC ayikwazi ukuhlanganiswa, okuholela ekunciphiseni kokusebenza kwesixhumi.
Imingcele eyisisekelo: ukulahlekelwa kokufaka, ukulahlekelwa kokubuyisela
Ngenxa yobuso obuhlukene bokuphela kwe-ferrule, ukusebenza kokulahlekelwa kwesixhumi nakho kuhlukile.Ukusebenza kokubona kwezixhumi ze-fiber optic kukalwa ngokuyinhloko ngamapharamitha amabili ayisisekelo: ukulahlekelwa kokufaka nokulahlekelwa kokubuyisela.Ngakho, yini ukulahlekelwa kokufaka?I-Insertion Loss (“IL”) ukulahleka kwamandla okubona ngenxa yoxhumo.Isetshenziswa kakhulu ukukala ukulahleka kokubona phakathi kwamaphoyinti amabili agxilile kufiber, ngokuvamile ngenxa yokuchezuka kwezinhlangothi phakathi kwemicu emibili, igebe longitudinal ku-fiber. i-fiber joint, ikhwalithi yobuso bokuphela, njll. Iyunithi ivezwa ngama-decibel (dB).Okuncane kuba ngcono, imfuneko evamile akufanele ibe ngaphezu kuka-0.5dB.
Ukulahlekelwa Kokubuyisela (“RL”) kubhekisela kupharamitha yokusebenza kokuboniswa kwesignali.Ichaza ukulahleka kwamandla kwesignali ye-optical return/reflection.Ngokuvamile, okukhudlwana kuba ngcono, inani livamise ukuvezwa ngama-decibel (dB).Isixhumi esivamile se-APC sinevelu ye-RL evamile cishe engaba ngu--60 dB futhi isixhumi se-PC sinevelu ye-RL evamile cishe engu- -30 dB.
Ngaphezu kwemingcele yokusebenza kwe-optical emibili yokulahlekelwa kokufaka nokulahlekelwa kokubuyisela, ukusebenza kwesixhumi se-fiber optic kufanele futhi sinake ukuguquguquka, ukuphindaphinda, amandla okudonsa kanye nezinga lokushisa lokusebenza kwesixhumi se-fiber optic., inani lokufakwayo nokunye.
Uhlobo lwesixhumi
Izixhumi zihlukaniswe ngokwendlela yokuxhuma: LC, SC, FC, ST, MU, MT, MPO/MTP, njll.;ngokusho kwe-fiber end face: FC, PC, UPC, APC.
Isixhumi se-LC
Isixhumi sohlobo lwe-LC senziwe ngendlela elula yokusebenzisa i-modular jack (RJ) latch mechanism.Usayizi wezikhonkwane nemikhono esetshenziswa kusixhumi se-LC ngu-1.25 mm, okuwusayizi we-SC evamile, i-FC, njll., ngakho usayizi wangaphandle uyingxenye kuphela ye-SC/FC.
Isixhumi se-SC
Isixhumi sesixhumi se-SC ('Isixhumi Sokubhalisela' noma 'Isixhumi Esivamile') yisixhumi esiyisikwele esivamile esisheshayo, esiboshelwa ukuxhuma nokukhipha, futhi asidingi ukuzungeziswa.Lolu hlobo lwesixhumi lwenziwe ngamapulasitiki wobunjiniyela, angabizi futhi kulula ukuwafaka nokuwakhipha.
Isixhumi se-FC
I-FC fibre connector (i-Ferrule Connector) nesixhumi se-SC zinosayizi ofanayo, ngaphandle kokuthi i-FC yenziwe ngomkhono wensimbi futhi indlela yokubopha i-turnbuckle.Imodeli yokusetshenziswa inezinzuzo zesakhiwo esilula, ukusebenza okulula, ukwakheka okulula nokuqina, futhi ingasetshenziswa endaweni yokudlidliza okuphezulu.
Isixhumi se-ST
Isixhumi se-ST fibre optic (Ithiphu eqondile) sinekesi yangaphandle eyindilinga enepulasitiki emise okwendandatho engu-2.5mm noma ikesi lensimbi.Indlela yokubopha i-turnbuckle, evame ukusetshenziswa kumafreyimu wokusabalalisa i-fiber.
Isixhumi se-MTP/MPO
Isixhumi se-MTP/MPO fibre optic siwuhlobo olukhethekile lwesixhumi se-multi-fiber.Isakhiwo sesixhumi se-MPO siyinkimbinkimbi, sixhuma imicu engu-12 noma engu-24 ku-rectangular fiber ferrule.Ivamise ukusetshenziselwa izimo zokuxhumanisa okuphezulu njengezikhungo zedatha.
Ngaphezu kwalokhu okungenhla, izinhlobo zezixhumi ziyizixhumi ze-MU, izixhumi ze-MT, izixhumi ze-MTRJ, izixhumi ze-E2000, nokunye okunjalo.I-SC cishe iyisixhumi se-fiber optic esisetshenziswa kakhulu, ikakhulukazi ngenxa yokwakheka kwayo okunezindleko eziphansi.Izixhumi ze-LC fibre optic nazo ziyi-fiber optic connector evame ukusetshenziswa, ikakhulukazi ekuxhumekeni kuma-transceivers e-SFP ne-SFP+ fiber optic.I-FC isetshenziswa kakhulu kwimodi eyodwa futhi ayitholakali kalula ku-multimode fiber.Imiklamo eyinkimbinkimbi kanye nokusetshenziswa kwensimbi kwenza kubize kakhulu.Izixhumi ze-ST fibre optic zivame ukusetshenziswa kuzinhlelo zokusebenza zebanga elide nelifushane njengekhampasi nezinhlelo zokusebenza zefiber ye-multimode yezakhiwo, izindawo zenethiwekhi yebhizinisi, nezinhlelo zokusebenza zempi.
