1. Muaj peev xwm sib txawv: hais lus cable yog siv los txuas lub zog loj thiab cov lus, thiab qhov dej ntws tam sim no ntws los hauv nws loj dua li ntawm lub cable cable thiab audio cable.
2. Cov ntaub ntawv sib txawv: cov hais lus cable yuav tsum muaj cov neeg coj tus cwj pwm qis thiab siab purity. Cov xov hlau siv nyob rau hauv hais lus cable raug npaj hauv kev sib ncag, yog li qhov cuam tshuam ntawm electromagnetic crosstalk yog me me. Cov xov hlau zoo nkauj muaj qis dua qhov yuav tsum tau ua dua li cov lus hais ntawm cov xov hlau cuam tshuam ntawm cov khoom, rwb thaiv tsev txheej thiab cov qauv hlau.
3. Txawv txawv: tus hais lus cable yog pa oxygen tooj liab hais lus cable nrog purity siab, mos hlau thiab zoo conductivity. Cov hlau xaim xaj xaim hluav taws xob xaim tooj liab, cov khoom siv yog qhov nyuaj, txawm tias lub zog yog siab dua li ntawm cov hais lus hlau, qhov conductivity zoo qis tshaj li ntawm cov lus hlau.
