Kev sib xyaw ua ke ntawm lub sijhawm kho qhov muag ntsia rov qab (OTDR), kho qhov muag tsis pom kev (OLTS), ntsuas fais fab (OPM) & ntsuas lub teeb yog qhov zoo heev hauv kev ua haujlwm thiab daim ntawv thov. Lawv tuaj yeem siv rau kev txhim kho cable thiab daim ntaub thaiv sab nraum zoov. xeem ntawv. Yog li cov lus nug tshwm sim: qhov koj nyiam xaiv? Niaj hnub no, cia peb hais txog peb qhov kev siv ntau dhau los ua ke: OTDR, OLTS, OPM & kuaj teeb pom kev sib xyaw.
Lub Sijhawm Optical Domain Reflectometer (OTDR). Txoj haujlwm ua haujlwm ntawm lub sijhawm ntsuas kho qhov muag pom yog zoo ib yam li radar. Nws lub ntsiab lus yog lub radical kho qhov muag. Lub sijhawm kho qhov muag ntawm lub tshuab ntsuas tus pas ntsuas qhov muag tau ua los ntawm kev xa cov hluav taws xob xa mus rau hauv cov roj carbon fiber ntau, thiab tom qab ntawd tau txais cov ntaub ntawv xa rov qab ntawm lub sij hawm kho qhov muag tau tsom qhov chaw nres nkoj tsom mus rau kev tshawb xyuas. Tsis tas li ntawd, muaj cov txheej txheem ntawm cov lus sib tham sib txawv los tshawb xyuas qhov poob ntawm qhov kho qhov muag fiber ntau hauv cov txheej txheem ntawm kev xa cov cim xaib.
Optical poob tester (Optical Poob Xeem Teeb, OLTS). Sab sab hauv tus ntsuas hluav taws xob tsis pom kev yog qhov sib txuas ua ke ntawm lub zog kho qhov muag thiab ntsuas qhov ntsuas qhov ntsuas hluav taws xob. Nws txoj kev kuaj mob tuaj yeem faib ua ob theem. Lub zog hluav taws xob yog sim ua ntej, thiab tom qab ntawd lub teeb ci los ntawm lub cuab yeej tau kuaj. Muaj qhov sib txawv ntawm cov cuab yeej poob ntawm ob qib no los ntawm kev sim.
Meter Optical zog (OPM) & kuaj lub teeb ua ke. Kev siv lub ntsuas siv hluav taws xob txuas siv ua ke nrog kev ntsuas kom ruaj khov ntawm lub teeb pom kev tuaj yeem ntsuas qhov txuas poob, xyuas txuas ntxiv, thiab pab ntsuas cov kab hluav taws xob txuas kis tau zoo. Nws cov haujlwm zoo ib yam li OLTS. Tab sis vim hais tias nws cov khoom siv hluav taws xob ib zaug thiab ob lub zog siv hluav taws xob tuaj yeem siv qhov kawg ntawm txhua qhov txuas, qhov qub tau hloov me ntsis piv rau lwm yam.
Nws yuav qhia nyob rau hauv cov nqe lus ntawm cov nqi, yooj yim ntawm kev siv, thiab thov.
1. Nqi: Piv nrog tus nqi ntawm peb yam khoom no, OTDR feem ntau kim dua. Ntxiv rau, piv nrog kev sib xyaw ntawm OLTS thiab OPM & kuaj teeb pom kev, OTDR yuav tsum muaj cov kws tshaj lij ua haujlwm, yog li nws cov nqi neeg yuav siab dua. Ntxiv rau, OTDR muaj cov cuab tam siab thiab tswj tus nqi. Yog tias koj siv OTDR tsis tu ncua, koj tuaj yeem xav yuav ib qho. Tab sis yog tias nws tsuas yog siv qee zaus, ces nws yog qhov tsim nyog los qev nws ntawm tus nqi xam pom. Raws li rau kev sib xyaw ntawm OLTS thiab OPM & kuaj teeb pom kev, vim hais tias qhov tom kawg yog tsim los ntawm ob lub khoom siv (qhov ntsuas hluav taws xob thiab ntsuas qhov teeb meem), muaj cov khoom siv ntau dua kev saib xyuas thiab tswj kev siv nyiaj, yog li kev siv tus nqi yuav siab dua me ntsis kho qhov muag ploj tester qee qhov.
2. Yooj yim ntawm kev siv: Raws li tau hais hauv kab lus dhau los, OTDR yuav tsum ua haujlwm los ntawm tus kws tshaj lij lossis cov neeg muaj lub ntsej muag, yog li los ntawm qhov pom ntawm qhov yooj yim ntawm kev siv, OTDR muaj ntsis qis dua. Vim tias cov neeg tsis paub ua haujlwm yuav tsis ua haujlwm ntawm OTDR, nws yuav siv qee lub sijhawm thiab lub zog los kawm thiab kawm siv nws. Raws li rau kev sib xyaw ntawm OPM thiab kuaj lub teeb pom kev, txij li nthwv dej ntawm nws lub teeb tsis tau yooj yim synchronized thaum kuaj, nws yuav muaj teeb meem me ntsis los ua haujlwm tshaj OLTS. Yog li no, ntawm peb qho no, qhov kev ntsuas qhov muag ploj tuag yog qhov yooj yim tshaj plaws ntawm cov khoom siv sim, thiab yuav luag txhua tus neeg tuaj yeem pib ua haujlwm sai.
3. Daim Ntawv Thov: OTDR yog siv rau kev ntsuam xyuas cov xov txuas sab nraud. Cov xov txuas sab nraud muaj kev cuam tshuam ntawm tib hom fiber ntau kom nws haum rau kev sib kis ntev. Lub luag haujlwm ntawm OTDR yog kuaj qhov zoo ntawm cov nplai fiber ntau splicing. Txawm li cas los xij, tom qab qhov kev sib txuas tiav, peb kuj yuav tsum siv OPM, kuaj lub teeb pom kev thiab siv cov xaim hluav taws xob los kuaj qhov ntxig tsis ua cov nqaij fiber ntau. OLTS feem ntau siv los ntsuas qhov kawg-rau-kawg poob ntawm qhov kev nruab. Nws yog yooj yim thiab txhim khu kev qha los ntawm kev siv txoj kev ntsuas ob-txoj kev ntawm ntau lub vojvoog. Raws li tau hais los saum toj no, siv OPM thiab cov khoom siv sib txuas yog qhov hloov tau ntau dua li OLTS. Feem ntau, ib qho OPM thiab cov khoom siv hluav taws xob sib xyaw ua ke tuaj yeem ua tiav qhov ntsuas qhov ntsuas ntawm ob OLTS, thiab nws tsis tas yuav ntsuas lub zog xa mus, yog li nws tsim nyog siv rau ntau qhov chaw.
Los ntawm kev tshuaj xyuas saum toj no,
a. Peb tuaj yeem pom tias tus nqi ntawm OTDR yog qhov ntau tshaj thiab haum rau cov kws tshaj lij siv.
b. OLTS muaj tus nqi qis kawg thiab yooj yim siv.
c. OPM thiab teeb ci sib xyaw ua ke nyob hauv nruab nrab.
Tag nrho txhua qhov, cov khoom siv fiber ntau ntawm cov khoom siv no yog qhov tseem ceeb ntawm cov cuab yeej fiber ntau, lawv tuaj yeem tshawb xyuas cov teeb meem nyob rau lub sijhawm ua ntej koj cov fiber ntau kho qhov muag dhau heev lawm. Tsuav koj tau paub txog lawv cov yam ntxwv, thiab raws li tus nqi, yooj yim ntawm kev siv, thiab thov ib puag ncig kev thov nyob rau hauv cov kev sim xaim cov txheej txheem, koj yuav tau yooj yim nrhiav "nws" uas haum koj zoo tshaj plaws.
