OTDR tester, tseem hu ua Optical Time Domain Reflectometer (OTDR), yog ib qho kev sib xyaw ua ke ntawm optoelectronic siv dav hauv kev saib xyuas thiab kev tsim kho cov kab hluav taws xob kho qhov muag. Nws tuaj yeem ntsuas qhov ntev ntawm optical fibers, kis tau tus mob attenuation ntawm optical fibers, sib koom attenuation, thiab qhov chaw txhaum. Txoj kev siv los ntawm OTDR tester yog raws li hauv qab no:
1. Qhib OTDR fais fab mov
2. Txuas fiber ntau optic connectors
3. Raws li lub wavelength thiab refractive index, teem lub hom xaiv, wavelength, nrug (automatically teem ua ntej, ces teem raws li nyob deb), mem tes dav, siab daws teeb meem, thiab kuaj lub sij hawm rau OTDR.
4. Pib OTDR pib ntsuas. Thaum lub sij hawm ntsuas cov txheej txheem, lub connector tsis tuaj yeem muab tshem tawm lossis ntsaws rau hauv, thiab lub qhov muag tsis tuaj yeem pom qhov hloov pauv hloov pauv ntawm qhov kawg ntawm cov khoom siv kho qhov muag.
5. Raws li cov khoom siv kho qhov muag sib txawv, ntsuas qhov ntev, qhov sib txawv ntawm qhov sib txawv, qhov nruab nrab poob, tag nrho poob, poob thiab attenuation coefficient ntawm ob lub ntsiab lus, movable sib koom ua ke poob, melting point poob, thiab lwm yam. Sau cov ntaub ntawv ntsuas thiab xam nws. Yuav kom txo tau qhov yuam kev, yuav tsum ntsuas bidirectional.
6. Sau cov ntaub ntawv nkhaus thiab txheeb xyuas lawv.
