Kev Ntsuas Kub Faib Tawm (DTS)
Kev Taw Qhia
Lub tshuab ntsuas kub uas siv cov khoom siv fiber ntau faib ua kab yog lub tshuab ntsuas kub sib txawv uas muaj cov cai tswjfwm kev txawj ntse ywj pheej uas lub tuam txhab tsim, uas siv cov txheej txheem ntsuas kub faib ua kab (DTS) tas mus li. Cov thev naus laus zis OTDR siab heev thiab lub teeb Raman tawg yog siv los ntes qhov kub hloov pauv raws li qhov chaw sib txawv ntawm cov fiber, uas tsis tsuas yog tuaj yeem kwv yees qhov hluav taws kom ruaj khov thiab raug, tab sis kuj tseem tuaj yeem nrhiav qhov chaw ntawm qhov hluav taws kom raug.
