Raws li cov tub ntxhais kis tau tus mob nruab nrab ntawm kev sib txuas lus kho qhov muag, kev ua haujlwm ntawm fiber ntau optic cables ncaj qha cuam tshuam rau kev ruaj ntseg thiab kev ntseeg siab ntawm kev ua haujlwm network. Cov txheej txheem xeem, qhov txuas tseem ceeb hauv kev ua kom cov khoom zoo, khiav thoob plaws lub neej tag nrho los ntawm cov khoom siv raw tuaj txog rau kev tsim khoom thiab xa khoom tiav. Los ntawm ntau-qhov ntev thiab ntau- qib kev sim thiab kev txheeb xyuas, nws ua kom paub tseeb tias cov kab hluav taws xob kho qhov muag ua tau raws li cov qauv ntawm kev ua haujlwm kho qhov muag, lub zog siv tshuab, thiab kev hloov pauv ib puag ncig, tso lub hauv paus ruaj khov rau kev xa xov hluav taws xob zoo.
Kev tshuaj xyuas cov khoom raw yog qhov pib ntawm cov txheej txheem, tsom rau kev tswj cov kev ua tau zoo ntawm cov fiber ntau preform thiab sheath cov ntaub ntawv. Lub preform, raws li "niam" ntawm optical fiber, yuav tsum tau mus rau refractive index profile tsom xam, doping uniformity xeem, thiab purity xeem kom paub tseeb tias nws geometric qhov ntev thiab kho qhov muag tsis raws li qhov tsim nyog yuav tsum tau, fundamentally tiv thaiv kis tau tus mob attenuation los yog tsis txaus bandwidth los ntawm cov khoom tsis xws luag. Cov ntaub ntawv sheath yuav tsum tau ua piv txwv rau tensile lub zog, thermal aging, dej nqus, thiab nplaim retardancy tests los xyuas nws cov neeg kho tshuab kev tiv thaiv thiab ib puag ncig tiv thaiv, tsis txhob tawg los yog tiv thaiv tsis ua hauj lwm nyob rau hauv lub sij hawm ntev - siv los ntawm substandard sheath kev ua tau zoo.
Kev saib xyuas online thaum lub sijhawm tsim khoom yog qhov tseem ceeb rau kev ua kom cov txheej txheem ruaj khov. Cov txheej txheem kev kos duab fiber ntau yuav tsum tau ua nyob rau hauv qhov siab - qhov chaw huv huv nrog qhov kub thiab av noo tas li, nrog rau lub sijhawm tiag tiag ntawm kev kos duab nrawm thiab txheej tuab los tiv thaiv kev puas tsuaj ntxiv los ntawm khawb ntawm cov fiber ntau nto los yog txheej tsis sib xws. Hauv cov txheej txheem txheej txheej thib ob, kev saib xyuas online txuas ntxiv taug qab cov txheej txheem extrusion kub, concentricity, thiab core stranding suab kom ntseeg tau tias cov qauv zoo ib yam thiab tsis muaj npuas thiab tawg. Kev tswj xyuas meej ntawm qhov chaw thiab qhov nro ntawm cov khoom siv txhawb zog yuav tsum tau kuaj xyuas qhov ua tau zoo ntawm cov khoom siv kom tsis txhob muaj qhov ntev - lub sij hawm deformation los ntawm kev ntxhov siab tsis sib xws ntawm lub cev cable. Cov -cov txheej txheem tshawb xyuas lub sijhawm tiag tiag tuaj yeem cuam tshuam cov txheej txheem sib txawv tam sim, ua kom muaj kev txuas ntxiv thiab sib xws ntawm cov txheej txheem tsim khoom.
Kev ntsuam xyuas cov khoom tiav yog theem tseem ceeb rau kev txheeb xyuas qhov kev ua tau zoo ntawm cov khoom siv kho qhov muag, npog peb qhov ntev: kev ua haujlwm kho qhov muag, kev ua haujlwm zoo, thiab kev hloov pauv ib puag ncig. Kev ntsuas kev ua haujlwm kho qhov muag yuav tsum ntsuas qhov fiber ntau optic attenuation coefficient, bandwidth, cutoff wavelength, thiab dispersion tsis. Feem ntau siv cov teeb pom kev zoo thiab cov khoom siv xws li optical fais fab ntsuas thiab lub sij hawm kho qhov muag -domain reflectometers (OTDRs) yog ua hauj lwm rau qhov kawg -mus rau-kawg los yog segmented xeem los xyuas kom meej kis tau tus mob specifications raws li tus qauv tsim. Kev ntsuas kev ua tau zoo ntawm cov tshuab suav nrog tensile, flattening, cuam tshuam, rov kho dua, thiab kev ntsuas torsion txhawm rau txheeb xyuas cov qauv kev ncaj ncees thiab kev ruaj ntseg ntawm cov kab hluav taws xob kho qhov muag nyob rau hauv qhov sib txawv ntawm lwm yam kev quab yuam. Kev ntsuas kev hloov pauv ib puag ncig suav nrog kev caij tsheb kauj vab siab thiab qis qis, damp tshav kub laus, ntsev tsuag tshuaj tiv thaiv, thiab kev ntsuas dej tsis zoo kom paub meej txog qhov ntev - lub sij hawm kev ntseeg siab ntawm cov khoom siv kho qhov muag hauv qhov chaw huab cua.
Ntawm - qhov kev lees paub qhov chaw yog cov kauj ruam kawg hauv cov txheej txheem, tsom mus rau kev txheeb xyuas qhov ua tau zoo ntawm cov kab hluav taws xob kho qhov muag hauv qhov chaw xa tawm tiag tiag. Ua ntej kev tsim kho, kev ntsuam xyuas attenuation thiab kev tshawb xyuas qhov ntev ntawm ib lub reel ntawm optical cable yuav tsum tau ua kom ntseeg tau qhov sib xws ntawm cov khoom tuaj thiab cov qauv tsim. Tom qab splicing, kev sib koom ua ke poob yog saib xyuas siv OTDR los tswj kev sib sau ua ke nyob rau hauv kev txwv. Tom qab tag nrho cov cable tau muab tso, kawg- mus rau- kawg kis tau tus mob retesting yog ua, thiab dispersion thiab nonlinear cuam tshuam raug soj ntsuam siv ib tug optical zog ntsuas thiab ib spectral analyzer kom paub meej tias lub system commissioning yuav tsum tau ua. Kev tshuaj xyuas ib ntus thaum lub sijhawm ua haujlwm tsom mus rau kev saib xyuas fiber ntau optic attenuation tiam sis thiab kev sib txuas ntawm kev huv, siv cov kev soj ntsuam ntse los kwv yees qhov tsis raug latent thiab muab cov ntaub ntawv txhawb kev tiv thaiv kev saib xyuas.
Cov txheej txheem kuaj fiber ntau optic ua raws li lub hauv paus ntsiab lus ntawm "tag nrho- voj voog kev pab them nqi thiab ntau- kev txheeb xyuas qhov ntev," kev ua haujlwm kaw - voj kev tswj cov khoom siv raw, kev soj ntsuam cov txheej txheem, cov khoom tiav tiav, thiab ntawm - qhov chaw lees txais kom txo qhov muaj feem cuam tshuam. Tsuas yog los ntawm kev siv cov txheej txheem nruj me ntsis no tuaj yeem ua rau qis - poob, kev sib kis tau zoo heev tau lees paub hauv cov cheeb tsam nyuaj, muab kev lav zoo rau siab - kev tsim kho zoo thiab ntev - lub sijhawm ua haujlwm ntawm kev sib txuas lus kho qhov muag.
