Igikorwa nyamukuru cya fibre optique ihuza ni uguhuza byihuse fibre ebyiri kugirango ibimenyetso bya optique bikomeze gukora inzira nziza.Ihuza rya fibre optique irigendanwa, irashobora gukoreshwa, kandi nibintu byingenzi kandi bikoreshwa cyane muri sisitemu yitumanaho rya optique. Ihuza rya fibre optique ryemerera amasura abiri yanyuma ya fibre guhuza neza na buto kugirango ihuze cyane ingufu za optique zisohoka kuva kwanduza fibre kugeza kuri fibre yakira, kandi ingaruka za sisitemu kubera intervention yayo igomba kugabanywa.Kuberako diameter yinyuma ya fibre ari 125um gusa, kandi igice gitambutsa urumuri ni gito, fibre yuburyo bumwe ni nka 9um gusa, naho fibre ya multimode ni 50um na 62.5um, bityo rero guhuza fibre bigomba kuba byukuri guhuza.
Ibice byingenzi: ferrule
Binyuze mu ruhare rwa fibre optique ihuza, birashobora kugaragara ko ibice byingenzi bigira ingaruka kumikorere yibihuza ni ferrule.Ubwiza bwa ferrule bugira ingaruka ku buryo butaziguye hagati ya fibre ebyiri. Ferrule ikozwe muri ceramic, metal cyangwa plastike.Ceramic ferrule ikoreshwa cyane, ibikoresho nyamukuru ni dioxyde ya zirconium, ifite ibimenyetso biranga ubushyuhe bwiza bwumuriro, ubukana bwinshi, aho gushonga cyane, kwambara birwanya no gutunganya neza.Ikiboko nikindi kintu cyingenzi kigize umuhuza, kandi amaboko akora nkumuhuza kugirango byorohereze kwishyiriraho.Diameter y'imbere ya ceramic ceramic ni ntoya gato kurenza diametre yinyuma ya ferrule, kandi urutoki rwacagaguye rukomera ferrule ebyiri kugirango zihuze neza.
Kugirango ukore isura yanyuma ya fibre ebyiri guhuza neza, impera ya ferrule isanzwe iba muburyo butandukanye.PC, APC, na UPC byerekana imbere yimbere yimbere yimiterere ya ceramic ferrule.PC ni Ihuza ry'umubiri, guhuza umubiri. PC ni micro-spherical surface isukuye kandi isukuye, hejuru ya ferrule iba hasi mubutaka buto, kandi intandaro ya fibre optique iherereye ahantu hirengeye hunamye kugirango amasura abiri ya fibre arangije guhura kumubiri.APC (Angled Physical Contact) yitwa guhuza umubiri, kandi isura ya fibre isanzwe iba hasi kugeza kuri 8 °.Umuhengeri wa 8 ° utuma fibre ya fibre irangira kandi ikagaragaza urumuri binyuze mu mpande zayo zometse ku cyerekezo aho gusubira mu isoko, bitanga imikorere myiza yo guhuza.UPC.Ihuza rihuza rigomba kuba muburyo bumwe bwo mumaso, urugero APC na UPC ntibishobora guhuzwa, bigatuma imikorere ihuza.
Ibipimo fatizo: igihombo cyo gushiramo, igihombo cyo kugaruka
Bitewe nuburyo butandukanye bwa ferrule amaherezo, imikorere yo gutakaza umuhuza nayo iratandukanye.Imikorere ya optique ya fibre optique ihuza cyane cyane ibipimo bibiri byibanze: igihombo cyo kwinjiza no gutakaza igihombo.None, igihombo cyo gushiramo ni iki?Gutakaza Insertion (“IL”) nigihombo cyamashanyarazi kubera guhuza.Bikoreshwa cyane mugupima igihombo cya optique hagati yibintu bibiri byagenwe muri fibre, mubisanzwe biterwa no gutandukana kuruhande hagati ya fibre zombi, ikinyuranyo kirekire muri fibre ihuriweho, ubwiza bwisura yanyuma, nibindi Igice kigaragarira muri decibels (dB).Gutoya nibyiza, ibisabwa muri rusange ntibigomba kurenza 0.5dB.
Gutakaza Igihombo (“RL”) bivuga ibipimo byerekana ibimenyetso byerekana ibimenyetso.Irasobanura gutakaza imbaraga zo guhitamo ibimenyetso bya optique kugaruka / gutekereza.Mubisanzwe, nini nini nziza, agaciro kagaragarira muri decibels (dB).Ihuza risanzwe rya APC rifite agaciro gasanzwe ka RL hafi -60 dB naho PC ihuza PC ifite agaciro gasanzwe ka RL hafi -30 dB.
Usibye ibice bibiri bya optique yibikorwa byo gutakaza no gutakaza igihombo, imikorere ya fibre optique ihuza kandi igomba kwitondera guhinduranya, gusubiramo, imbaraga zingana nubushyuhe bwimikorere ya fibre optique., umubare winjiza nibindi.
Ubwoko bwumuhuza
Abahuza bagabanijwe bakurikije uburyo bwo guhuza: LC, SC, FC, ST, MU, MT, MPO / MTP, nibindi.;ukurikije isura ya fibre yanyuma: FC, PC, UPC, APC.
Umuhuza LC
Ubwoko bwa LC bwihuza bukozwe nuburyo bworoshye-bwo gukoresha modular jack (RJ).Ingano yipine nintoki zikoreshwa muguhuza LC ni 1,25 mm, nubunini bwa SC isanzwe, FC, nibindi, bityo ubunini bwo hanze ni kimwe cya kabiri cyicya SC / FC.
Umuhuza wa SC
Umuhuza wa SC uhuza ('Umukoresha Uhuza' cyangwa 'Standard Connector') ni snap-on isanzwe ihuza kare, ifunzwe no gucomeka no gupakurura, kandi ntigomba kuzunguruka.Ubu bwoko bwihuza bukozwe muri plastiki yubuhanga, buhendutse kandi byoroshye gushiramo no kuvanaho.
Umuhuza wa FC
Umuhuza wa fibre ya FC (Ferrule Connector) hamwe na SC uhuza ubunini bungana, usibye ko FC ikozwe mumaboko yicyuma kandi uburyo bwo gufunga ni impinduka.Icyitegererezo cyingirakamaro gifite ibyiza byuburyo bworoshye, imikorere yoroshye, gukora byoroshye kandi biramba, kandi birashobora gukoreshwa mubidukikije bihindagurika.
Umuhuza wa ST
Umuyoboro wa ST fibre optique (Impanuro ya Straight) ifite uruzitiro ruzengurutse ruzengurutswe na plastike cyangwa icyuma cya 2.5mm.Uburyo bwo gufunga ni impinduka, ikoreshwa muburyo bwo gukwirakwiza fibre.
MTP / MPO umuhuza
MTP / MPO fibre optique ihuza ubwoko bwihariye bwa fibre fibre.Imiterere ya MPO ihuza iragoye, ihuza fibre 12 cyangwa 24 muri ferrule y'urukiramende.Mubisanzwe bikoreshwa murwego rwo hejuru rwihuza nkibintu byamakuru.
Usibye hejuru yavuzwe haruguru, ubwoko bwihuza ni MU uhuza, umuhuza wa MT, umuhuza wa MTRJ, E2000 uhuza, nibindi nkibyo.SC birashoboka ko ikoreshwa cyane ya fibre optique ihuza cyane cyane bitewe nigiciro cyayo gito.LC fibre optique nayo ihuza fibre optique ihuza cyane cyane guhuza SFP na SFP + fibre optique.FC ikoreshwa cyane muburyo bumwe kandi ni gake muri fibre ya multimode.Ibishushanyo bigoye no gukoresha ibyuma bituma bihenze cyane.ST fibre optique ihuza mubisanzwe ikoreshwa murwego rurerure kandi rugufi nka campus hamwe nubwubatsi bwa multimode fibre yububiko, ibidukikije byumushinga, hamwe nibikorwa bya gisirikare.
