Vim li cas ho tsis siv Khoov Fiber Optic Cable Txo Rendis Rendant?
Fiber optic lag luam tau pom muaj kev siv ntau ntxiv ntawm cov khoom siv fiber ntau cable. FTTx tes hauj lwm yog lub zog ua rau kev saws fais fab. Thaum lub teeb tsa ntawm cov cables, xav paub ntxiv txog cov nyom ntawm khoov vojvoog thiab yuav tsum tswj kom muaj kev ruaj khov rau khoov kab hlau. Li ntawd, nyob deb, koj tseem txhawj xeeb txog dabtsi yog khoov fiber ntau cab? Khoov cov khoov fiber ntau opticitive yuav pab koj daws qhov teeb meem no.
Khoov Radius ntawm Fiber Optic Cable
Vim tias fiber ntau hauv fiber ntau yog muaj kev ntxhov siab, lub teeb yuav tawm thaum tawm lub fib. Thaum txoj hlua khaus ua ntau dua, muaj ntau lub teeb txau tawm (pom hauv daim duab hauv qab no). Yog li, thaum nruab ib lub cab cab thaj, qhov tshwj xeeb tshaj yog nyob rau hauv qhov chaw nruj ntawm qhov chaw sib ntau, qhov koj yuav tsum tsis txhob khoov dua lawv cov vojvoog. Dab tsi hauv ntiaj teb lub khoov vojvoog?
Dab tsi yog Rendered Radius thiab Minimum Rend Radius ntawm Fiber Optic Cable?
Khoov vojvoog yog khoov rau qhov uas yuav tshwm sim tau ua ntej kab xev tuaj yeem tiv thaiv kev puas tsuaj los yog muaj kev ntxhov siab ntxiv thiab txwv kev ua haujlwm bandwidth. Thaum ib lub tshuab fiber ntau yog khoov tshaj tawm, qhov teeb meem kho qhov muag tsis pub dhau lub cable yuav thim thiab kev khiav tawm ntawm cov hlua khoob. Ntxoov ntxoo kuj tseem tuaj yeem ua rau lub plab puas tsuaj tas li los ntawm qhov ua rau muaj kab tawg. Qhov tshwm sim yog hu ua khoov ploj: qhov poob ntawm lub teeb liab uas yuav ua rau kom muaj kev ncaj ncees ntawm cov ntaub ntawv xa tawm.
Lus Cim: Ntau nrawm nrawm thiab cov nruj nruj nruj heev dhau los kuj tseem ua tau rau cov teeb meem kis kab mob thiab micro-bends nyob rau hauv optical fiber cables.
Qhov tsawg kawg ntawm txoj hlua khi luv yog qhov tsawg tshaj plaws ntawm lub vojvoog rau ib lub xov tooj cua fiber optic uas tau muab khi rau. Tus txheej txheem tshiab ANSI / TIA / EIA-568B.3 teev cov qauv kev ua haujlwm, yam tsawg kawg ntawm txoj hlua kev sib tw thiab qhov siab tshaj plaws tension rau 50/125-micron thiab 62.5 / 125-micron fiber optic cables. Rau sab hauv lub tshuab fais fab, fiber ntau khoov vojvoog yog 10 npaug ntawm kab ntawv sab nraud nyob hauv qab tsis pub rub tawm, thiab 15 zaug rau kab sab nraud thaum lub pob tensile load.
Yuav ua li cas Laij Rend Rendant ntawm Fiber Optic Cable?
Feem ntau, qhov khij nyiab khoov vov nws txawv ntawm kab hom, sab nraum lub thawv (OD), thiab qhov teeb meem ntawm lub xov tooj cua nyob rau hauv kev nyuab siab thaum lub sij hawm ntsia (tensile load) thiab tom qab kev txhim kho thaum lub cable pib dua (tsis-thauj khoom). Cov qauv hauv qab no yog siv los laij khoov voos kheej kheej:
Qhov tsawg tshaj plaws Khoov Radius = Cable Txuas Twj Kab Cable Cable
Lub cable txuas yog txiav txim siab los ntawm cov qauv kev lag luam thiab cable hom. Rau cov kab mob fiber ntau, cov cable txuas tshaj yog 6 zaug rau cables kwv yees 5000 volts los yog tsawg, yim zaug rau cov cables uas tshaj 5000 volts.
Dab tsi yog Khoov Insensitive Fiber Optic Cable?
Khoov insensitive fiber ntau lub cable yog tsim los muab kev sib txuas nrog tsawg poob txawm tias lawv khoov duav dhau qhov khoov vojvoog. Nyob rau hauv cov BIF Optical Cables, ib qhov muag "trench" - lub nplhaib ntawm qis index ntawm refraction khoom - yog ua rau hauv cov fibre kom pom qhov teeb ploj rov qab rau hauv tub ntxhais ntawm cov fiber ntau, yog li ua kom tsis muaj ntaub ntawv poob. Khoov insensitive fiber cable muaj ntau dua kev yooj yim hauv cov kev xav tau ntau dua cov kab nyug fiber ntau. Nws feem ntau yog siv hauv cov chaw zov me nyuam los yog ib qhov chaw uas txwv tsis pub muaj qhov khoov kom nruj thiab yuav tsum tau yooj yim. Kev khoov pob khawm cov khib nyiab muaj nyob rau hauv 50/125 MMF (OM3 thiab OM4) thiab 9/125 SMF versions.
Khoov Insensitive Multimode Fiber Optic Cable (BIMMF)
Multimode fiber ntau nyob rau hauv cov chaw zov me nyuam cov ntaub ntawv thiab lub tsev ntawm lub tsev pob txha caj qaum. Nyob rau hauv lub era ntawm nce txuas, xav tau ntau dua ntawm qhov zoo thiab kev ua tau zoo ntawm qhov txuas txuas tau ntau dua. Tshiab khoov cov khoos phom ntau ntawm cov tshuab fiber ntau minimizes khoov rau qhov kev cuam tshuam, uas pab tsim kom muaj kev ruaj ntseg thiab txo cov sijhawm. Cov BIMMF cables yog muaj nyob rau hauv tag nrho cov laser optimized qib, OM2, OM3 thiab OM4, thiab tuaj yeem 10 lub sij hawm tsawg lub teeb liab poob rau hauv nruj khoov scenarios. Lub fiber yuav muab ntsia rau hauv loops me me li 7.5 hli vojvoog nrog tsawg dua 0.2dB dabtsi yog khoov ntawm 850nm thiab 0.5dB ntawm 1300nm.
Khoov Insensitive Ib hom Fiber Optic Cable (BISMF)
Hauv 2007, ib hom tshiab "khoov-insensitive" ib hom fiber ntau yog nkag tau. Nws tuaj yeem tiv kev ntxhov siab los ntawm kev sib tw, sib zog, los yog ncab tsis muaj kev txom nyem zoo. ITU qhov kev pom zoo G.657 qhia ob chav kawm ntawm ib hom khoov rau cov khauj khawm tsis muaj fiber ntau: G.657 A thiab G.657 B. Qhov tsawg kawg ntawm txoj hlua ntawm G.657. A1 fibers yog 10 hli, ntawm G.657. A2 thiab G.657.B1 fibers yog 7.5 hli thiab ntawm G.657.B2 fibers yog 5 hli. Piv nrog cov qauv qis luv luv ntawm tus qauv G652 fibers uas feem ntau yog 30 hli, G.657 ib hom khoov khov rau cov khauj khab ntau lub khauj khawm yooj yim dua. Li no, BISMF cables tau confidently ntsia nrog ntau txoj kev installation thiab nyob rau hauv qhov chaw nce high-density daim ntawv thov ntawm hnub no lub chaw data.
Zoo ntawm Khoov Cuav Cov Fiber Optic Cable
Yooj Yim Sib Sau
Khoov cov kab hlau hluav taws xob khov heev rau cov chaw siv hluav taws xob sab hauv tsev uas lawv siv tam sim no yuav tsum tau los ntawm cov phab ntsa, ncej, tav, ducts, thiab lwm yam tsis sib txig hauv cov vaj tse uas tsis muaj kev txhawj xeeb txog ntau cov khoov fiber ntau.

Tib Hom Taw
Khoov cov kabmob tsis muaj kabmob yuav raug siv los siv tib txoj kev siv rau cov cab cab.
Kev sib haum ntawm Khoov Fend Optic Cable
Khoov insensitive fiber optic cable muaj ntau yam zoo. Ib nqe lus nug tej zaum yuav tshwm sim: puas yog cov BIF Optical Cable tshaj li niaj zaus fibers? Cov lus teb zoo li yuav yog rau txhua tus SMF cables. Vim tias tsuas muaj ib hom kev coj ua hauv cov hauv paus, qhov trench muaj feem cuam tshuam txog kev ua haujlwm thiab kev ntsuas. Tab sis rau MMF cables, nws tsis tshua meej. Kev ntsuas ntawm qhov loj, hom txawv qeeb (DMD) thiab bandwidth tau tsim ua ntej kev qhia txog BIMMF cov qauv. Cov kev ntsuas no yog nyob rau hauv tus txheej txheem ntawm kev raug soj ntsuam thiab kev hloov tshiab thiaj li yuav nyob ntawm seb qhov chaw tsim khoom ntawm BIMMF.
FOCC khoov ntxig rau Fiber Optic Cable Solutions
FOCC khoov khov rau cov khauj khaum loj heev uas ua rau cov khauj khaum raug siab heev. Lawv muaj ib txoj hlua khi me me uas tsis muaj zog thiab tiv thaiv kom tsis txhob ntxiv nyiaj vim cov tsim tawm tshiab thiab ua kom tsis muaj zog txaus siab heev. Cov fais fab cab no muaj nyob rau hauv cov ntawv yooj yim thiab duplex, ua ke ntawm SC thiab LC fiber optic cable connectors nrog UPC thiab APC kev xaiv.
