Tej Yam Koj Yuav Tsum Tau Paub Txog Kev Siv Fiber Optic Cable Siv
Dab tsi yog Fiber Optic Cable?
Cov roj carbon fiber ntau cable, lossis optical fiber cable, yog ib hom network cable zoo ib yam li tooj liab cable. Nws yog tsim los siv cov hluav taws xob sib xyaw rau cov xov tooj sib txuas ntev thiab cov ntaub ntawv xa xov ceev. Cov kab hluav taws xob fiber ntau pab txhawb ntau lub ntiaj teb hauv Is Taws Nem, cable TV thiab xov tooj.
Piv nrog rau tooj liab tooj liab, fiber ntau kab hluav taws xob muab cov kab hluav taws xob ntau dua thiab tuaj yeem xa cov ntaub ntawv hla ntev dua li cov tuab zoo sib xws. Feem ntau, cov roj carbon fiber ntau them rau kab hluav taws xob ceev ntawm 10 Gbps, 40 Gbps thiab txawm tias 100 Gbps.
Feem ntau, ib lub fiber ntau cov xaim hluav taws xob ua los ntawm cov iav tsis pom kev zoo los yog yas uas hu ua cov xov hluav taws xob (hu ua "core") uas muaj ib puag ncig uas tsis muaj qhov thaiv (hu ua “cladding). Txhua txoj hlua yog me ntsis tuab dua li tib neeg cov plaub hau thiab tuaj yeem nqa ntau cov ntaub ntawv zoo li 25,000 kev hu xov tooj. Yog li no, ib qho tag nrho cov roj carbon fiber ntau tau yooj yim nqa cov ntaub ntawv ntau npaum li koj tuaj yeem xav.
Cov kev xav ntawm Fiber Optic Cable Siv: Nws Ua Haujlwm Li Cas?
Lub ntsiab lus fiber ntau thiab cladding khoov tuaj rau ntawm lub teeb ci ntawm lub kaum sab xis nrog lawv tus kheej qhov ntsuas qhov ua kom zoo nkauj. Thaum cov cim hluav taws xob tau xa los ntawm cov kab xa hluav taws xob fiber ntau, lawv xav txog qhov tseem ceeb thiab txhaws rau hauv cov kab sib chaws, uas cov txheej txheem hu ua tag nrho cov kev xav sab hauv.
Fiber Ntau Optic Cable Siv
Nws yog qhov yuav tsum tau kawm txog kev sib txawv ntawm cov kab mob fiber ntau cable thaum koom nrog kev thov ntawm kev sib txuas lus fiber ntau. Muaj ob hom thawj cov roj carbon fiber ntau, tib hom fiber ntau (SMF) thiab multimode fiber (MMF). Lub qub muaj cov tub ntxhais nyias heev txog 5-10 microns hauv qhov taub, uas yog li 10 feem pua ntawm tom kawg. Feem ntau, ib hom kho qhov muag kab siv hauv kev sib txuas xov tooj tau khiav lag luam ntawm 1310nm lossis 1550nm wavelength thaum multimode fiber ntawm 850nm thiab 1300nm. Txawm li cas los xij, qee zaum, qhov kev faib tawm ntawm ob hom yog qhov txawv vim muaj ntau yam cov lag luam fiber ntau cable.
Raws li rau kev siv cov xov tooj fiber ntau cable, tib hom kho qhov muag fiber ntau cable siv rau cov chaw nyob ntev dua xws li 100km piv nrog multimode fiber ntau hauv qab 2km vim yog qhov taub me me ntawm fiber fiber. Yog li no, tib hom kho qhov muag kab no feem ntau siv sab nraum nruab nrab ntawm cov tsev hauv TV TV, internet, thiab xov tooj xa xov kis thaum cov xov tooj hluav taws xob multimode siv nyob rau hauv cov tuam tsev hauv cov caj qaum xws li computer sib txuas.
Cov npe siv rau hauv qab no yog cov siv fiber ntau cable siv:
Kev Siv Network: Nws tuaj yeem siv los txuas cov neeg siv thiab cov servers hauv txawv network chaw thiab kuj tseem tuaj yeem ua kom lub nrawm thiab raug ntawm cov ntaub ntawv xa mus.
Xov tooj cua thiab TV: Tshaj tawm hauv xov tooj cua thiab TV tau xa mus rau pua pua lab ntawm tsev neeg los ntawm cov kab hluav taws xob.
Hluav taws xob lub zog hluav taws xob: Tsim lub tshuab sib txuas ntawm cov hluav taws xob ua haujlwm nrog kev ua haujlwm kho qhov muag sib txuas nrog cov kab hluav taws xob thiab cov chaw hais kom ua.
Railway system: Cov kev sib txuas lus ntawm cov tsheb nqaj hlau, cov paib thiab cov xa hluav taws xob sib txuas yog tsim los ntawm cov kab hluav taws xob fiber ntau.
Pej xeem lub tsheb ceev ceev: Cov vev xaib video rau pej xeem kev ruaj ntseg yog tsim los ntawm cov kho qhov muag.
Kho Mob: Nws yog siv raws li cov coj kev teeb, cov cuab yeej kos duab thiab tseem yog cov lasers rau kev phais.
Kev Tiv Thaiv / Tsoomfwv: Nws yog siv los ua hydrophones rau seismic thiab sonar hom phiaj, raws li cov xov hlau hauv dav hlau, submarines thiab lwm lub tsheb thiab ntxiv rau kev sib tham.
Kev Lag Luam / Kev Lag Luam: Nws yog siv rau kev ntsuas hauv thaj chaw nyuaj.
Kev siv teeb pom kev zoo: Cov kab hluav taws xob fiber ntau tuaj yeem siv ua teeb pom kev zoo.
Qhov xaus ntawm Fiber Optic Cable Siv
Txhua yam, muaj ntau cov kab xo fiber ntau siv kev koom tes hauv peb lub neej. Ntxiv rau cov ntawv thov tau hais los saum toj no hauv ntau lub tshuab xws li xov tooj cua thiab TV, thev tso hluav taws xob, kev tsheb nqaj hlau, thiab lwm yam, cov hlua hluav taws xob fiber ntau yog qhov tseem ceeb hauv kev thoob ntiaj teb zoo ib yam.
