Ua kom ntseeg tau qhov kev sib txuas zoo, txo qis qhov tsis ua haujlwm, thiab nrhiav cov ntsiab lus fiber ntau thaum lub sijhawm ua haujlwm tsis zoo
Fiber optic testing yog cov txheej txheem siv los ntsuas qhov ua tau zoo ntawm ib qho -hom thiab ntau- hom fiber ntau optic systems. Nws lub hom phiaj los xyuas kom meej qhov kev sib txuas ntawm fiber ntau zoo, txo qhov ua tsis tiav, thiab pom qhov chaw ua txhaum sai sai. Nws lub hom phiaj tseem ceeb suav nrog kev txheeb xyuas qhov kev ntseeg tau ntawm kev sib txuas thiab ntsuas qhov ntsuas qhov tsis sib xws.
Kev ntsuam xyuas yog categorized rau hauv phau ntawv qhia yooj yim ntsuas thiab ntsuas ntsuas ntsuas, nrog cov teeb liab attenuation raws li qhov tseem ceeb metric. Multimode fiber ntau yuav tsum tau ntsuas qhov ntsuas ntawm 850nm lossis 1300nm wavelengths, thaum ib zaug - hom fiber ntau xav tau ntau dua. Cov khoom xeem suav nrog kev sib txuas, kawg - mus rau - kawg attenuation, thiab kev ntsuam xyuas cov khoom poob. Kab rov tav subsystems feem ntau dhau ib zaug - wavelength testing, whereas backbone systems yuav tsum tau dual - wavelength xeem. Ua raws li TIA / EIA cov qauv, cov cuab yeej zoo li FTK200 yog siv los kuaj. Tag nrho qhov txuas attenuation yog xam los ntawm summing fiber cable poob thiab connector poob.
