Mu myaka mike ishize, insinga ya fibre optique imaze kubahendutse.Ubu irakoreshwa kubintu byinshi bisaba ubudahangarwa bwuzuye kubangamira amashanyarazi.Fibre nibyiza kuri sisitemu yo hejuru-igipimo cya sisitemu nka FDDI, multimediya, ATM, cyangwa urundi rusobe rwose rusaba kohereza dosiye nini, zitwara igihe.
Ibindi byiza bya fibre optique hejuru yumuringa harimo:
• Intera nini-Urashobora gukoresha fibre kugera kuri kilometero nyinshi.• Kwiyerekana gake-Ibimenyetso byurumuri bihura nuburwanya buke, kugirango amakuru arashobora kugenda kure.
• Umutekano-Kanda muri fibre optique byoroshye kubimenya.Iyo ikubiswe, umugozi usohora urumuri, bigatuma sisitemu yose inanirwa.
• Umuyoboro munini-Fibre irashobora gutwara amakuru menshi kuruta umuringa.• Ubudahangarwa-Fibre optique irinda kwivanga.
Ubwoko bumwe cyangwa multimode?
Fibre imwe-imwe iguha igipimo cyinshi cyo kohereza kandi inshuro zigera kuri 50 kurenza multimode, ariko kandi igura byinshi.Fibre imwe-fibre ifite intoki ntoya kuruta fibre fibre-mikoro 5 kugeza 10.Gusa urumuri rumwe rushobora kwanduzwa mugihe runaka.Intangiriro ntoya hamwe numucyo umwe ukuraho rwose kugoreka kwose guturuka kumurabyo wumucyo utanga urumuri, bitanga ibimenyetso byibuze byihuta kandi byihuta cyane byogukwirakwiza ubwoko bwa fibre fibre.
Fibre fibre iguha umurongo mwinshi kumuvuduko mwinshi kure.Amatara maremare akwirakwizwa munzira nyinshi, cyangwa uburyo, mugihe zinyuze mumurongo wa kabili.Ubusanzwe diameter ya multimode fibre yibanze ni 50, 62.5, na micrometero 100.Nyamara, mumurongo muremure ukoresha (hejuru ya metero 3000 (914.4 ml), inzira nyinshi zumucyo zirashobora gutuma ibimenyetso bigoreka kumpera yakira, bikavamo ihererekanyamakuru ridasobanutse kandi rituzuye.
Gupima no kwemeza fibre optique.
Niba umenyereye kwemeza umugozi wicyiciro cya 5, uzatungurwa cyane nukuntu byoroshye kwemeza umugozi wa fibre optique kuva niba udafite ubudahangarwa bwumuriro.Ukeneye gusa gusuzuma ibipimo bike:
• Attenuation (cyangwa igihombo cya decibel) -Bipimye muri dB / km, iyi ni igabanuka ryimbaraga za signal nkuko inyura mumashanyarazi ya fibre optique.• Garuka igihombo-Ingano yumucyo igaragarira kumpera ya kabili igaruka kumasoko.Hasi umubare, nibyiza.Kurugero, gusoma -60 dB biruta -20 dB.
• Urwego rwohejuru rwerekana indangagaciro-Gupima urumuri rwoherejwe munsi ya fibre.Ibi bipimirwa muburebure bwa 850 na 1300 nanometero.Ugereranije nizindi mikorere ikora, izi ntera zombi zitanga imbaraga zo hasi cyane.(ICYITONDERWA Ibi biremewe kuri fibre fibre gusa.)
• Gutinda kwamamaza-Iki nicyo gihe bisaba ikimenyetso cyo kugenda kuva kumurongo umwe ujya kurundi hejuru y'umuyoboro.
• Igihe-indangarubuga yerekana (TDR) -Yohereza impiswi nyinshi cyane kuri kabili kugirango ubashe gusuzuma ibizagerwaho kumurongo hanyuma utandukanya amakosa.
Hano hari isoko ryinshi rya fibre optique ku isoko muri iki gihe.Ibipimo fatizo bya fibre optique ikora mugucana urumuri kumpera imwe ya kabili.Ku rundi ruhande, hariho imashini yakira imbaraga zumucyo utanga urumuri.Hamwe niki kizamini, urashobora gupima urumuri rugana kurundi ruhande rwumugozi.Mubisanzwe, abapimisha baguha ibisubizo muri decibels (dB) yatakaye, hanyuma ukagereranya na bije yigihombo.Niba igihombo cyapimwe kiri munsi yumubare wabazwe na bije yawe yigihombo, kwishyiriraho ni byiza.
Ibizamini bishya bya fibre optique bifite ubushobozi bwagutse.Barashobora kugerageza ibimenyetso 850- na 1300-nm icyarimwe kandi barashobora no kugenzura Gable yawe kugirango yubahirize ibipimo byihariye.
Igihe cyo guhitamo fibre optique.
Nubwo insinga ya fibre optique iracyahenze kuruta ubundi bwoko bwinsinga, itoneshwa kubitumanaho byihuta byamakuru kuko bikuraho ibibazo byumugozi uhindagurika, nka hafi ya cross-cross (NEXT), kwivanga kwa electronique (EIVII), no guhungabanya umutekano.Niba ukeneye umugozi wa fibre ushobora gusurawww.mireko-cable.com.
