Yuav kom paub tseeb tias cov yam ntxwv ntawm kev siv cov teeb liab kis tau deb thiab tsis poob qis, cov kab hluav taws xob fiber optic yuav tsum ua tau raws li qee qhov xwm txheej ib puag ncig. Txhua qhov kev khoov me me lossis kev ua qias tuaj ntawm cov kab hluav taws xob optical tuaj yeem ua rau cov teeb liab optical tsis zoo thiab txawm tias cuam tshuam kev sib txuas lus.
1. Qhov ntev ntawm txoj kab fiber optic cable
Vim yog cov yam ntxwv ntawm cov xov hluav taws xob thiab qhov tsis sib xws hauv cov txheej txheem tsim khoom, cov teeb liab teeb pom kev zoo uas kis mus rau hauv lawv tas li diffuse thiab raug nqus. Thaum qhov txuas fiber optic cable ntev dhau, nws yuav ua rau tag nrho qhov attenuation ntawm cov teeb liab teeb pom kev zoo ntawm tag nrho qhov txuas kom dhau qhov yuav tsum tau ua ntawm kev npaj network. Yog tias qhov attenuation ntawm cov teeb liab teeb pom kev zoo loj dhau, nws yuav txo qhov cuam tshuam kev sib txuas lus.
2. Lub kaum sab xis ntawm qhov chaw tso cable optical loj dhau
Qhov kev khoov thiab kev nias ntawm cov xov hluav taws xob optical yog qhov tshwm sim los ntawm kev hloov pauv ntawm cov xov hluav taws xob optical, uas ua rau tsis muaj peev xwm ua kom tau raws li qhov kev cuam tshuam tag nrho thaum lub sijhawm xa hluav taws xob. Cov xov hluav taws xob fiber optic muaj qee qib ntawm kev khoov tau, tab sis thaum cov xov hluav taws xob fiber optic khoov rau qee lub kaum sab xis, nws yuav ua rau muaj kev hloov pauv ntawm qhov kev taw qhia ntawm cov teeb liab optical hauv cov xov hluav taws xob, ua rau muaj kev khoov. Qhov no yuav tsum tau ua tib zoo saib xyuas kom tawm hauv cov kaum sab xis txaus rau kev tsim kho xov hlau.
3. Fiber optic cable raug nias lossis tawg
Qhov no yog qhov yuam kev feem ntau ntawm cov teeb meem ntawm cov xov hluav taws xob optical. Vim yog lub zog sab nraud lossis kev puas tsuaj ntuj tsim, cov fibers optical yuav muaj qhov khoov me me lossis txawm tias tawg. Thaum qhov tawg tshwm sim hauv lub thawv splice lossis optical cable, nws tsis tuaj yeem pom los ntawm sab nraud. Txawm li cas los xij, ntawm qhov chaw tawg ntawm fiber, yuav muaj kev hloov pauv ntawm cov ntsuas refractive, thiab txawm tias qhov poob ntawm kev cuam tshuam, uas yuav ua rau qhov zoo ntawm cov teeb liab xa mus ntawm cov fiber puas tsuaj. Ntawm qhov no, siv lub tshuab ntsuas cable optical OTDR los ntes qhov ncov kev cuam tshuam thiab nrhiav qhov kev khoov sab hauv lossis qhov tawg ntawm cov fiber optical.
4. Kev sib koom ua ke ntawm fiber optic fusion tsis ua haujlwm
Thaum lub sijhawm tso cov xov hluav taws xob optical, cov khoom siv fiber fusion splicer feem ntau siv los sib txuas ob ntu ntawm cov fiber optic rau hauv ib qho. Vim yog qhov sib txuas ntawm cov iav fiber hauv txheej tseem ceeb ntawm cov xov hluav taws xob optical, nws yog qhov tsim nyog siv cov khoom siv fusion splicer kom raug raws li hom xov hluav taws xob optical thaum lub sijhawm tsim kho qhov chaw sib txuas. Vim yog qhov kev ua haujlwm tsis ua raws li cov lus qhia tsim kho thiab kev hloov pauv hauv qhov chaw tsim kho, nws yooj yim rau cov fiber optic kom muaj av qias neeg, ua rau muaj cov khoom tsis huv sib xyaw thaum lub sijhawm sib txuas thiab ua rau qhov zoo ntawm kev sib txuas lus ntawm tag nrho cov txuas.
5. Lub cheeb ntawm cov xov hlau fiber ntau txawv
Kev tso cov cable fiber optic feem ntau siv ntau txoj kev sib txuas, xws li kev sib txuas flange, uas feem ntau siv rau hauv kev tso cov network computer hauv cov tsev. Kev sib txuas nquag feem ntau muaj kev poob qis, tab sis yog tias qhov kawg ntawm cov fiber optical lossis flange tsis huv thaum lub sijhawm sib txuas nquag, txoj kab uas hla ntawm cov fiber optical fiber tseem ceeb sib txawv, thiab qhov sib koom ua ke tsis nruj, nws yuav ua rau qhov sib koom ua ke poob ntau heev. Los ntawm OTDR lossis kev sim fais fab ob kawg, qhov tsis sib xws ntawm txoj kab uas hla ntawm cov fiber tseem ceeb tuaj yeem pom. Nws yuav tsum tau sau tseg tias cov fiber ib hom thiab cov fiber ntau hom muaj cov hom kev sib kis sib txawv kiag li, wavelengths, thiab hom kev txo qis tshwj tsis yog txoj kab uas hla ntawm cov fiber tseem ceeb, yog li lawv tsis tuaj yeem sib xyaw.
6. Kev sib kis ntawm cov khoom siv fiber optic
Kev ua qias tuaj ntawm cov fiber sib koom ua ke thiab cov dej noo ntawm cov fiber yog cov ua rau cov cable optical tsis ua haujlwm. Tshwj xeeb tshaj yog nyob rau hauv cov tes hauj lwm sab hauv tsev, muaj ntau cov fiber luv luv thiab ntau yam khoom siv hloov pauv network, thiab kev ntxig thiab tshem tawm cov fiber optic connectors, flange hloov, thiab kev hloov pauv yog qhov ntau heev. Thaum lub sijhawm ua haujlwm, cov hmoov av ntau dhau, kev ntxig thiab rho tawm poob, thiab kev kov ntiv tes tuaj yeem ua rau cov fiber optic connector qias neeg, ua rau tsis tuaj yeem kho txoj kev kho qhov muag lossis lub teeb tsis zoo ntau dhau. Yuav tsum siv cov phuam cawv los ntxuav.
7. Kev txhuam tsis zoo ntawm qhov sib koom ua ke
Kev txhuam tsis zoo ntawm cov pob qij txha kuj yog ib qho ntawm cov teeb meem tseem ceeb hauv cov fiber optic txuas. Qhov zoo tagnrho fiber optic cross-section tsis muaj nyob rau hauv qhov chaw tiag tiag, thiab muaj qee qhov undulations lossis slopes. Thaum lub teeb nyob rau hauv lub optical cable txuas ntsib xws li ib tug cross-section, qhov sib koom ua ke tsis sib xws ua rau diffuse scattering thiab reflection ntawm lub teeb, uas ua rau kom lub teeb attenuation ntau heev. Ntawm lub nkhaus ntawm OTDR tester, lub attenuation cheeb tsam ntawm qhov tsis zoo polished seem yog loj dua li ntawm lub ntsej muag kawg ib txwm.
Cov teeb meem cuam tshuam nrog fiber optic yog cov teeb meem pom tseeb tshaj plaws thiab feem ntau tshwm sim thaum lub sijhawm debugging lossis kev saib xyuas. Yog li ntawd, yuav tsum muaj ib lub cuab yeej los xyuas seb lub teeb ci ntawm fiber optic puas zoo li qub. Qhov no yuav tsum tau siv cov cuab yeej kuaj mob fiber optic, xws li cov ntsuas fais fab optical thiab cov cwj mem teeb liab. Cov ntsuas fais fab optical yog siv los kuaj qhov poob ntawm kev xa xov fiber optic thiab yooj yim siv, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev daws teeb meem ntawm cov teeb meem fiber optic. Lub cwj mem teeb liab yog siv los nrhiav seb lub fiber optic nyob rau ntawm lub disc fiber optic twg. Ob lub cuab yeej tseem ceeb no rau kev daws teeb meem ntawm cov teeb meem fiber optic, tab sis tam sim no lub ntsuas fais fab optical thiab cwj mem teeb liab tau muab tso ua ke rau hauv ib lub cuab yeej, uas yooj yim dua.
