Umsebenzi oyinhloko wezixhumi ze-fiber optic ukuxhuma ngokushesha imicu emibili, okuvumela amasignali optical ukuba aqhubeke futhi enze izindlela ze-optical. Izixhumi ze-Fiber optic ziyagudluka, zisebenziseka kabusha, futhi njengamanje ziyizinto ezibalulekile zokungenzi lutho ezisetshenziswa kakhulu ezinhlelweni zokuxhumana ezibonakalayo. Ngokusebenzisa izixhumi ze-fiber optic, ubuso obubili bokugcina be-fiber bungaxhunywa ngokunembile, okuvumela ukuhlanganisa okuphezulu kokukhishwa kwamandla optical kusuka ku-fiber yokudlulisa kuya ku-fiber eyamukelayo, nokunciphisa umthelela ohlelweni olubangelwa ukungenelela kwalo. Ngenxa yokuthi ububanzi obungaphandle be-fiber optical buyi-125um kuphela, futhi ingxenye yokudlulisela ukukhanya incane, i-fiber optical mode eyodwa imayelana ne-9um kuphela, futhi kunezinhlobo ezimbili zemicu ye-multimode optical: 50um kanye ne-62.5um. Ngakho-ke, ukuxhumana phakathi kwemicu ye-optical kudinga ukuvumelanisa ngokunembile.
Ingxenye eyinhloko: ipulaki
Ngendima yezixhumi ze-fiber optic, kungabonakala ukuthi ingxenye eyinhloko ethinta ukusebenza kwesixhumi iwumgogodla wepulaki. Ikhwalithi yokufaka ithinta ngokuqondile ukudokha okumaphakathi okunembayo kwemicu emibili yokubona. Izinto ezisetshenziselwa ukwenza ukufaka zihlanganisa i-ceramic, insimbi, noma ipulasitiki. Ukufakwa kwe-Ceramic kusetshenziswa kakhulu, ikakhulukazi okwenziwe nge-zirconia, ngokuzinza okuhle kokushisa, ukuqina okuphezulu, indawo yokuncibilika okuphezulu, ukumelana nokugqoka, nokunemba okuphezulu komshini. Umkhono ungenye ingxenye ebalulekile yesixhumi, esisebenza njengokuqondanisa ukuze kube lula ukufakwa nokulungiswa kwesixhumi. Ububanzi bangaphakathi bomkhono we-ceramic buncane kancane kunobubanzi obungaphandle bokufaka, futhi umkhono oboshiwe uqinisa ama-cores amabili afakayo ukuze afinyelele ukuqondanisa okunembile.
Ukuze kuqinisekiswe ukuthintana okungcono phakathi kobuso bokugcina bemicu emibili yokubona, ubuso bokuphela kwepulaki buvamise ukugaywa ezinhlakeni ezahlukene. I-PC, i-APC, ne-UPC imele uhlaka lwangaphambili lokufakwa kwe-ceramic. I-PC ukuxhumana ngokomzimba. I-PC igaywe futhi ipholishelwe endaweni engaphansi kwe-microsphere, futhi ingaphezulu lokufakiwe ligaywa libe yindawo encane eyindilinga. I-fiber core itholakala endaweni ephakeme kakhulu yokugoba, ukuze ubuso obubili bokuphela kwefiber bufinyelele ukuthintana ngokomzimba. I-APC (I-Angled Physical Contact) ibizwa ngokuthi ukuxhumana ngokomzimba okuthambekele, futhi ubuso bokuphela kwefayibha ngokuvamile buphansi bufinyelele ku-8 ° indiza ethambekele. Irempu ye-engeli engu-8 ° yenza isiphetho sefayibha ubuso buqine futhi ibonise ukukhanya nge-engeli yayo yerempu kuya ekuhlanganisweni esikhundleni sokubuyela ngokuqondile kumthombo wokukhanya, inikeze ukusebenza okungcono koxhumo. I-UPC (Ultra Physical Contact), ubuso bokuphela bomzimba obuhle kakhulu. I-UPC ilungiselela ukupholishwa kobuso ekugcineni kanye nokuqedwa kwendawo ngesisekelo se-PC, okwenza ubuso bokuphela bubonakale bufana ne-dome. Uxhumano lwesixhumi ludinga ukuba nesakhiwo sobuso bokuphela okufanayo, njenge-APC ne-UPC ayikwazi ukuhlanganiswa ndawonye, okungaholela ekwehleni kokusebenza kwesixhumi.
Imingcele eyisisekelo: ukulahlekelwa kokufaka, ukulahlekelwa kokubuyisela
Ngenxa yobuso obuhlukene bokugcina bokufaka, ukusebenza kokulahlekelwa kwesixhumi nakho kuyahlukahluka. Ukusebenza kokubona kwezixhumi ze-fiber optic kukalwa ngokuyinhloko ngamapharamitha amabili ayisisekelo: ukulahlekelwa kokufaka nokulahlekelwa kokubuyisela. Ngakho, kuyini ukulahlekelwa kokufaka? Ukulahleka Kokufaka (okuvame ukubizwa ngokuthi "L") ukulahleka kwamandla okusebenza okubangelwa ukuxhumana. Ikakhulu isetshenziselwa ukukala ukulahleka kokubona phakathi kwamaphoyinti amabili agxilile kumafiber optical, ngokuvamile okubangelwa ukuchezuka kwezinhlangothi phakathi kwemicu emibili yokubona, igebe longitudinal kusixhumi se-fiber, ikhwalithi yobuso bokuphela, njll. Iyunithi ivezwa ngamadecibel (dB), kanye kuncane inani, kungcono. Ngokuvamile, akufanele idlule i-0.5dB.
I-Return Loss (RL), evame ukubizwa ngokuthi "RL", ibhekisela kupharamitha yokusebenza kokuboniswa kwesignali, echaza ukulahleka kwamandla okubuyisela isignali ye-optical/reflection. Ngokuvamile, okukhudlwana kuba ngcono, futhi inani livamise ukuvezwa ngama-decibel (dB). Inani elivamile le-RL lezixhumi ze-APC licishe libe ngu--60dB, kuyilapho kuzixhumi ze-PC, inani elivamile le-RL lingaba ngu--30dB.
Ukusebenza kwezixhumi ze-fiber optic kudinga ukucatshangelwa kwakho kokubili ukulahlekelwa kokufaka nokulahlekelwa kokubuyisela
Ngokungeziwe kumapharamitha wokusebenza kokubona, lapho kukhethwa isixhumi esihle se-fiber optic, ukunakwa kufanele futhi kukhokhwe ekushintsheni, ukuphindaphinda, amandla aqinile, izinga lokushisa lokusebenza, izikhathi zokufaka nezokukhipha, njll. kwesixhumi se-fiber optic.
Uhlobo lwesixhumi
Izixhumi zihlukaniswe zibe yi-LC, SC, FC, ST, MU, MT ngokwezindlela zabo zokuxhuma
I-MPO/MTP, njll; Ngokusho kobuso be-fiber end, ihlukaniswe i-FC, i-PC, i-UPC, ne-APC.
Izixhumi ze-LC
Isixhumi sohlobo lwe-LC senziwe kusetshenziswa umshini we-latch we-modular jack (RJ) okulula ukuwusebenzisa. Usayizi wezikhonkwane nemikhono esetshenziswa kuzixhumi ze-LC ngokuvamile ngu-1.25mm uma kuqhathaniswa nalowo osetshenziswa ku-SC evamile, i-FC, njll., ngakho usayizi wabo wokubukeka uyingxenye kuphela yalowo we-SCFC.
Isixhumi se-SC
Isixhumi sesixhumi se-SC (Isixhumi Sokubhalisa 'noma Isixhumi Esivamile') siwukufinyeza kusixhumi esiyisikwele esivamile, futhi indlela yokubopha iwuhlobo lwe-latch ye-plug-in ngaphandle kwesidingo sokuzungezisa. Lolu hlobo lwesixhumi lwenziwe ngepulasitiki yobunjiniyela, eshibhile futhi kulula ukuyifaka nokuyikhipha.
Isixhumi se-FC
Usayizi wesixhumi se-FC fibre optic nesixhumi se-SC siyefana, kodwa umehluko ukuthi i-FC isebenzisa umkhono wensimbi futhi indlela yokubopha ibhande lesikulufu. Isakhiwo silula, sisebenza kalula, kulula ukwenza, sihlala isikhathi eside, futhi singasetshenziswa ezindaweni zokudlidliza okuphezulu.
Izixhumi ze-T-ST
Igobolondo lesixhumi se-ST fibre optic (Ithiphu eqondile) liyisiyingi futhi lamukela ipulasitiki eyindilinga engu-2.5mm noma igobolondo lensimbi, ngendlela yokubopha yesikulufu. Isetshenziswa kakhulu kumafreyimu wokusabalalisa i-fiber optic
Isixhumi se-MTP/MPO
Isixhumi se-MTP/MPO se-fiber optic siwuhlobo olukhethekile lwesixhumi se-multifiber optic.
Isakhiwo sezixhumi ze-MPO siyinkimbinkimbi, sixhuma ama-optical fibers angu-12 noma angu-24 endaweni efaka i-fiber optical engunxande. Imvamisa isetshenziswa ezimeni zokuxhumanisa okuphezulu kakhulu, njengezikhungo zedatha, ngaphezu kwalokhu okungenhla, izinhlobo zezixhumi zifaka izixhumi ze-MU, izixhumi ze-MT, izixhumi ze-MTRJ, izixhumi ze-E2000, njll. I-SC ingase ibe isixhumi se-fiber optic esisetshenziswa kakhulu njengamanje, ikakhulukazi. ngenxa yomklamo wayo obiza kancane. Izixhumi ze-LC fibre optic nazo ziwuhlobo oluvamile
Isixhumi esisetshenziswa kakhulu se-fiber optic, ikakhulukazi sokuxhuma kuma-transceivers e-SFP ne-SFP+fiber optic. I-FC ivamise ukusetshenziswa kumafayibha emodi eyodwa futhi ayivamile uma kuqhathaniswa kumafayibha e-multimode. Idizayini eyinkimbinkimbi kanye nokusetshenziswa kwezinsimbi kwenza kubize kakhulu. Izixhumi ze-ST fibre optic zivame ukusetshenziselwa izinhlelo zokusebenza zamabanga amade namafushane, njengekhampasi nokwakha izinhlelo zokusebenza ze-multimode fibre optic, izindawo zenethiwekhi yebhizinisi, nezinhlelo zezempi.
I-Yiyuantong inikeza ukucaciswa okuhlukahlukene nezinhlobo zezixhumi ze-fiber optic, kuhlanganise ne-SC
F ukuxhumana. Ibhizinisi eliyinhloko lenkampani
Umkhiqizo yilokhu: isixhumi se-fiber optic (isikhungo sedatha isixhumi esibonakalayo se-high-density), i-wavelength division multiplexing
Imishini emithathu eyisisekelo ye-optical passive basic, okuhlanganisa izihlukanisi kanye nezihlukanisi ezibonakalayo, asetshenziswa kabanzi kuma-optical fibers.
Ikhaya nekhaya, ukuxhumana kweselula kwe-4G/5G, isikhungo sedatha ye-inthanethi, ukuxhumana kokuvikela izwe, njllinkambu
