Txhawm rau kom ntseeg tau tias daim ntawv thov cov yam ntxwv ntawm qhov ntev-ntev thiab tsis tshua muaj kev sib kis ntawm qhov muag pom, cov kab fiber ntau optic yuav tsum ua tau raws li qee qhov kev mob ntawm lub cev. Ib qho me me dabtsi yog khoov deformation los yog kis kab mob ntawm optical cables yuav ua rau attenuation ntawm optical signals thiab txawm cuam tshuam kev sib txuas lus.
1. Fiber optic cable routing kab ntev
Vim lub cev yam ntxwv ntawm optical cables thiab lub unevenness nyob rau hauv cov txheej txheem ntau lawm, lub optical signals propagated nyob rau hauv lawv yog tas li diffusing thiab absorbed. Thaum lub fiber optic cable txuas ntev dhau lawm, nws yuav ua rau tag nrho cov attenuation ntawm cov teeb liab kho qhov muag ntawm tag nrho cov txuas kom dhau qhov yuav tsum tau ntawm kev npaj network. Yog tias qhov attenuation ntawm lub teeb liab optical loj dhau, nws yuav txo qhov kev sib txuas lus.
2. Lub kaum sab xis ntawm qhov chaw kho qhov muag cable yog qhov loj heev
Qhov khoov attenuation thiab compression attenuation ntawm optical cables yog qhov tseem ceeb los ntawm qhov deformation ntawm optical cables, uas ua rau tsis muaj peev xwm ua kom tag nrho cov kev xav ntawm kev xav thaum lub sijhawm kho qhov muag. Fiber optic cables muaj qee qhov kev hloov kho tau yooj yim, tab sis thaum lub fiber optic cable yog khoov rau ib lub kaum ntse ntse, nws yuav ua rau muaj kev hloov pauv ntawm kev nthuav tawm ntawm cov teeb liab kho qhov muag hauv cable, uas ua rau khoov attenuation. Qhov no yuav tsum tau saib xyuas tshwj xeeb kom tawm cov ces kaum txaus rau kev xaim thaum tsim kho.
3. Fiber optic cable yog compressed los yog tawg
Qhov no yog qhov txhaum feem ntau hauv optical cable tsis ua haujlwm. Vim yog sab nraud quab yuam lossis kev puas tsuaj ntuj tsim, cov fibers optical tej zaum yuav muaj kev khoov me me los yog tawg. Thaum qhov tawg tshwm sim hauv lub thawv splice lossis optical cable, nws tsis tuaj yeem kuaj pom los ntawm sab nraud. Txawm li cas los xij, ntawm qhov taw tes ntawm fiber ntau tawg, yuav muaj kev hloov pauv hauv qhov ntsuas tsis pom kev, thiab txawm tias qhov kev xav tsis zoo, uas yuav ua rau qhov tsis zoo ntawm cov teeb liab kis ntawm fiber ntau. Txij ntawm no, siv OTDR optical cable tester kom pom txog qhov kev xav ntawm kev khoov sab hauv lossis pob txha lov ntawm lub ntsuas hluav taws xob.
4. Fiber optic kev sib koom ua ke fusion tsis ua haujlwm
Nyob rau hauv tus txheej txheem ntawm kev tso kho qhov muag cables, fiber ntau fusion splicers feem ntau yog siv los fuse ob seem ntawm optical fibers rau hauv ib qho. Vim lub fusion splicing ntawm cov iav fiber nyob rau hauv cov tub ntxhais txheej ntawm lub optical cable, nws yog tsim nyog los siv lub fusion splicer kom raug raws li hom ntawm optical cable thaum lub sij hawm tsim kho qhov chaw fusion splicing txheej txheem. Vim tias kev ua haujlwm tsis ua raws li kev tsim kho tshwj xeeb thiab kev hloov pauv hauv kev tsim kho ib puag ncig, nws yog qhov yooj yim rau cov khoom siv fiber ntau kom tsis txhob muaj cov av, ua rau cov impurities sib xyaw thaum lub sij hawm fusion splicing txheej txheem thiab ua rau txo qis hauv kev sib txuas lus zoo ntawm tag nrho cov txuas.
5. Fiber tub ntxhais hlau txoj kab uas hla txawv
Fiber optic cable nteg feem ntau siv ntau yam kev sib txuas ua haujlwm, xws li kev sib txuas flange, uas feem ntau siv hauv computer network nteg hauv tsev. Cov kev sib txuas nquag feem ntau muaj qhov poob qis, tab sis yog tias qhov kawg ntawm lub ntsej muag ntawm lub ntsej muag fiber ntau lossis flange tsis huv thaum lub sijhawm sib txuas, txoj kab uas hla ntawm cov tub ntxhais kho qhov muag fiber ntau sib txawv, thiab qhov sib koom ua ke tsis nruj, nws yuav ua rau kev sib koom ua ke poob zoo heev. Los ntawm OTDR lossis dual kawg lub zog kuaj, cov tub ntxhais txoj kab uas hla tsis sib haum tuaj yeem kuaj pom. Nws yuav tsum raug sau tseg tias ib hom fiber ntau thiab ntau hom fiber ntau muaj cov qauv sib txawv kiag li, wavelengths, thiab attenuation hom tshwj tsis yog rau txoj kab uas hla ntawm cov tub ntxhais fiber ntau, yog li lawv tsis tuaj yeem sib xyaw.
6. Fiber optic connector kab mob
Tail fiber ntau sib kis kab mob thiab fiber ntau hla dej noo yog lub ntsiab ua rau kho qhov muag cable tsis ua hauj lwm. Tshwj xeeb tshaj yog nyob rau hauv cov tes hauj lwm sab hauv tsev, muaj ntau cov fibers luv luv thiab ntau yam kev hloov pauv hauv lub network, thiab kev ntxig thiab tshem tawm ntawm fiber ntau optic connectors, flange hloov, thiab hloov tau ntau zaus. Thaum lub sijhawm ua haujlwm, cov plua plav ntau dhau, kev tso tawm thiab tshem tawm poob, thiab cov ntiv tes kov tuaj yeem ua rau cov fiber ntau optic connector qias neeg, ua rau tsis muaj peev xwm kho qhov kho qhov muag lossis teeb pom kev ntau dhau. Caw swabs yuav tsum tau siv los ntxuav.
7. Kev polishing tsis zoo ntawm qhov sib koom ua ke
Kev polishing tsis zoo ntawm cov pob qij txha kuj yog ib qho ntawm cov teeb meem tseem ceeb hauv kev sib txuas ntawm fiber ntau optic. Qhov zoo tshaj plaws fiber ntau optic cross-section tsis muaj nyob rau hauv lub cev tiag tiag, thiab muaj qee qhov undulations lossis slopes. Thaum lub teeb nyob rau hauv qhov kev sib txuas ntawm optical cable ntsib xws li ntu ntu, qhov tsis sib xws ntawm qhov sib koom ua ke ua rau muaj qhov sib txawv ntawm qhov sib txawv thiab qhov cuam tshuam ntawm lub teeb, uas ua rau kom lub teeb pom kev zoo. Ntawm qhov nkhaus ntawm OTDR tester, qhov attenuation cheeb tsam ntawm qhov tsis zoo polished seem yog loj dua li ntawm lub ntsej muag kawg.
Fiber optic cuam tshuam txog kev ua txhaum yog qhov pom tseeb tshaj plaws thiab nquag faults thaum lub sij hawm debugging lossis tu. Yog li ntawd, yuav tsum muaj ib qho cuab yeej los xyuas seb qhov fiber ntau optic lub teeb emission puas zoo li qub. Qhov no yuav tsum tau siv cov cuab yeej kuaj xyuas qhov txhaum ntawm fiber ntau, xws li cov ntsuas hluav taws xob kho qhov muag thiab cov cwj mem liab. Cov ntsuas hluav taws xob kho qhov muag tau siv los ntsuas qhov kev sib kis ntawm fiber ntau optic thiab yog cov neeg siv zoo heev, yooj yim, thiab siv tau yooj yim, ua rau lawv xaiv zoo tshaj plaws rau kev daws teeb meem fiber ntau optic. Lub teeb liab cwj mem yog siv los nrhiav qhov twg fiber optic disc lub fiber optic nyob rau. Ob lub cuab yeej tseem ceeb no rau kev daws teeb meem fiber ntau optic faults, tab sis tam sim no lub ntsuas hluav taws xob kho qhov muag thiab lub teeb liab cwj mem tau muab tso rau hauv ib qho cuab yeej, uas yooj yim dua.
