Fiber optic cable kev tsim kho yog kwv yees muab faib ua cov kauj ruam hauv qab no: Kev npaj → routing project → fiber optic cable nteg → fiber optic cable splicing → project txais.
1. Kev npaj
(1) tshawb xyuas cov ntaub ntawv tsim, raw khoom, cov cuab yeej tsim kho, thiab cov cuab yeej ua tiav.
(2) teem ib pab neeg ua haujlwm zoo. Qhov no yog qhov tseem ceeb heev vim tias kev siv fiber ntau optic dua li kev tsim kho cable yuav tsum nruj dua. Ib qho kev tsis saib xyuas hauv kev tsim kho yuav ua rau muaj fiber ntau poob lossis txawm tias cov tub ntxhais tawg.
2. Routing engineering
(1) ua ntej tso lub fiber optic cable yuav tsum xub ua ib qho kev soj ntsuam loj ntawm txoj kev los ntawm fiber ntau optic cable. Nkag siab txog kev tsim kho thiab kev npaj hauv zos, sim zam lub pas dej, hom qoob mog, chaw nres tsheb roj, thiab lwm yam uas muaj peev xwm zais kev phom sij. Tom qab txoj kev txiav txim siab, qhov tseeb ntsuas ntawm nws qhov ntev yog ua tiav, yog nyob rau hauv 50m. Kuj, ntxiv lub ntuj khoov thiab ntau yam tshwj xeeb ntev thaum xa tawm. Ntau yam kev tshwj tseg kuj suav nrog kev ntxig ntawm dabtsi yog khoov hauv lub qhov, reservation ntawm tus ncej, reservation ntawm ob qhov kawg ntawm kev sib koom ua ke, thiab lwm yam tshwj xeeb tshwj xeeb tshwj xeeb xws li nce curvature ntawm lub dav hlau kab rov tav. Yuav kom ua rau lub fiber optic cable nyob rau hauv cov kev tshwm sim ntawm ib tug so thiab ces splice, yuav tsum tau sab laug ntawm txhua puas meters nrog ib tug tej yam margin, qhov ntev ntawm cov npoo yog feem ntau 5% rau 10%. Txiav txim raws li qhov ntev xav tau thiab qhia meej thaum winding lub tais.
(2) Kos cov duab kos duab. Numbering rau lub pre-cog ncej, kos daim duab kos duab thiab qhia tus naj npawb ntawm txhua tus ncej lossis cov yeeb nkab hauv av qhov hluav taws xob thiab qhov ntev ntawm cov yeeb nkab. Teem tawm qhov ntev thiab qhov chaw ntawm qhov yuav tsum tau tawm ntawm cov npoo. Qhov no tuaj yeem siv qhov ntev ntawm fiber ntau optic cable, ib tug tsim nyog configuration kom lub fusion splice point yog minimized.
(3) Ob lub fiber optic pob qij txha yog qhov zoo tshaj plaws muab tso rau hauv ib lub tiaj tus, geologically ruaj khov qhov chaw. Zam lub pas dej, tus dej, kwj dej, thiab txoj kev, nyiam dua nyob ntawm qhov tawm ntawm tus ncej lossis cov yeeb nkab. Overhead fiber optic cable txuas yuav tsum tau poob ntawm tus ncej 0.5 ~ 1 m os, txoj haujlwm no yog hu ua “faib phaj”. Lub phaj tsim nyog yuav txo tau qhov fusion point. Ntxiv rau, cov duab kos duab yuav tsum qhia qhov chaw ntawm qhov chaw fusion, thaum lub fiber optic cable breakpoint, nws yog ib qho yooj yim los siv cov cuab yeej siv ceev nrooj kom pom qhov tawg rau kev txij nkawm.
3 fiber optic cable tso
(1) tib batch ntawm optical fiber, nws hom teb txoj kab uas hla yog yeej tib yam, fiber nyob rau ntawm qhov chaw ntawm disconnection, nruab nrab ntawm ob qhov kawg ntawm hom teb, tuaj yeem suav tau tib yam. Yog li ntawd, fusion splicing nyob rau hauv no disconnect point yuav ua rau hom teb txoj kab uas hla ntawm lub fiber fusion poob mus rau qhov tsawg kawg nkaus. Yog li xav tau cov chaw tsim khoom cable nrog tib pawg ntawm liab qab fiber ntau, raws li qhov yuav tsum tau muaj ntawm cov kab ntev ntev ntau lawm, nyob rau hauv txhua lub tais ntawm qhov sib lawv liag ntawm tus lej, thiab raug cim A (xim liab), B (ntsuab) kawg, tsis muaj tus lej dhia. Erection ntawm fiber ntau optic cables yuav tsum tau muab tso rau raws li kev txiav txim routing ib ntus raws li tus naj npawb thiab xyuas kom meej tias B kawg ntawm lub tais yav dhau los ntawm fiber optic cable txuas nrog A kawg ntawm lub tais tom ntej ntawm fiber ntau optic cable.. Txhawm rau kom ntseeg tau tias qhov sib txuas ntawm ob qhov kawg fiber ntau qhov diameters yog qhov zoo ib yam kom cov fusion poob tus nqi ua tiav qhov tsawg kawg nkaus..
(2) overhead fiber ntau optic cable yuav siv tau 72.2 hli galvanized steel stranded hlau rau dai cable ncua kev kawm ntawv. Dai hlau thiab fiber optic cable kom zoo-grounded, kom muaj xob laim, hluav taws xob ntsuas, thiab av qeeg, cua mechanical zog. Nyiaj siv ua haujlwm dai hlau thiab fais fab kab kab rov tav thiab ntsug nrug rau ntau tshaj 2m, los ntawm hauv av mus rau qhov siab tsawg kawg yog 5m, los ntawm lub ru tsev mus rau qhov tsawg kawg nkaus ntawm 1.5m. Overhead fiber optic cable dai hom muaj peb hom: hanging hlau hanging bracket hanging hom, dai hlau winding hom, thiab hom kev txhawb nqa tus kheej. Kev txhawb nqa tus kheej yam tsis muaj steel stranded hanging hlau, kab sagging, cua tsis zoo, yog li feem ntau siv dai hom.
(3) overhead fiber optic cable tso. Vim qhov ntev ntawm lub reel tshaj lub cable, qhov ntev yuav ncav cuag ob peb kilometers, nws raug txwv los ntawm qhov tso cai ntsuas nruj thiab khoov vojvoog, tshwj xeeb hauv kev tsim kho tsis tuaj yeem rub tawm thiab qhov tshwm sim ntawm kink phenomenon. General fiber optic cable tuaj yeem tso cai rub tawm 150 ~ 200 kg. Cov kab hluav taws xob khoov lub vojvoog yuav tsum ntau dua lossis sib npaug 10 ~ 15 lub sij hawm sab nraud txoj kab uas hla ntawm kab, thiab kev tsim kho ntawm lub vojvoog dabtsi yog khoov yuav tsum ntau dua lossis sib npaug 20 lub sij hawm lub deployment. Txhawm rau kom tsis txhob muaj fiber ntau optic cable tso rau hauv nruab nrab ntawm txoj kev, txog 20m deb ntawm tus ncej, txhim tsa nyob rau hauv ob qho kev taw qhia, thawj ib nrab ntim, nyob rau hauv lub thib ob ib nrab ntim ntawm fiber optic cable los ntawm lub phaj nqes. Raws li cov “8” hom kev hauv av, thiab tom qab ntawd deployment.
(4) nyob rau hauv qhov chaw ntawm cable, txwv tsis pub lub cable ua si lub voj voog me me thiab quav, twist, thiab yuav tsum tau nruab nrog ib tug xov tooj ntawm cov intercoms. Tus “pem hauv ntej taug kev raws li txoj kab ntawm lub xub pwg nyom” txoj kev ntawm kev tso cable, tuaj yeem tiv thaiv qhov tshwm sim ntawm lub nraub qaum buckle. Kuj, xyuam xim rau lub zog txawm, lub zog traction tsis tshaj 80% ntawm txoj kab tso cai, thiab lub siab tshaj plaws instantaneous traction quab yuam tsis tshaj 100%. Ntxiv rau, thaum erecting, nyob rau hauv lub khoov ntawm lub cable los yog ntau complex struts yuav tsum tau lub luag hauj lwm rau lub tsheb yog nruj me ntsis txwv tsis pub mus tsoo. Kev siv lub taub hau ntawm fiber ntau optic cable siv lub tsheb pulley, pre-hanging pulleys ntawm tus ncej pas nrig thiab dai kab (feem ntau txhua 10 ~ 20m dai ib lub pulley), nyob rau hauv lub fiber optic cable coj mus rau lub pulley, coj mus rau lub pulley kom txo tau cov drape, txo qhov nro. Tom qab ntawd hnav ib txoj hlua traction zoo nruab nrab ntawm lub pulleys, traction hlua khi rau lub taub hau traction ntawm lub cable, nrog rau qee yam traction kom cia lub cable nce mus txog tus ncej khib, dai ntawm txoj kab dai. Fiber optic cable nuv sib nrug ntawm 40cm, nuv nyob rau hauv cov kev taw qhia ntawm hitch ntawm kab hanger kom zoo ib yam. Txhua tus ncej yuav tsum muaj ib tug convex drip gutter, thiab txhua lub tais ntawm fiber ntau optic cable yuav tsum tau sab laug ntawm qhov sib koom nrog ib tus ncej ntev ntxiv rau 3m ntawm cov npoo. Yog li ntawd lub splice lub thawv hauv av fusion ua haujlwm, thiab txhua ob peb puas meters kom muaj ib lub phaj nyob.
4. Fiber optic cable splicing
Cov fiber ntau optic cables yog laminated, cev pob txha, thiab center pob tube fiber optic cables. Cov xim ntawm cov tub ntxhais yog muab faib ua qhov kev txiav txim no, txiv kab ntxwv, ntsuab, xim av, grey, dawb, dub, xim liab, xim daj, ntshav liab, liab, thiab txiv qaub ntsuab, uas yog hu ua tag nrho-xim spectrum ntawm cov tub ntxhais. Qee cov fiber optic cable manufacturers siv “xiav” hloov ib qho xim hauv cov xim spectrum. Multicore fiber optic cable rau cov xim sib txawv ntawm fiber ntau hauv tib lub pob ntawm cov hlab los ua ib pawg, yog li ib tug multicore fiber optic cable yuav muaj ob peb pob. Qhov hla-section ntawm fiber ntau optic cable, lub pob liab liab raj raws li thawj pob khoom ntawm fiber ntau optic cable, clockwise rau tus dawb, dawb ob, dawb peb …… kawg yog lub pob ntsuab raj. Hauv fiber optic splicing, txoj cai yuav tsum ua raws: tus naj npawb ntawm cov cores yog sib npaug. Nyob rau hauv tib lub pob ntawm cov xim sib xws fiber ntau pob tw, tus naj npawb ntawm cov cores txawv nyob rau tib lub sijhawm, nyob rau hauv thiaj li yuav xub txuas cov tub ntxhais ntawm qhov loj, ces lub hauv paus ntawm qhov me me.
Cov saum toj no yog “yuav ua li cas teeb fiber optic cable?” Kuv vam tias nws yuav pab tau koj.
