Coaxial cable los ntawm kev siv cov ntsiab lus muaj peev xwm raug muab faib ua theem pib kab hluav taws xob thiab broadband coaxial cable (xws li, network coaxial cable thiab video coaxial cable). Coaxial cable 50Ω kab cable thiab 75Ω broadband cable ob pawg. Kab hauv qab baseband yog subdivided los ntawm coaxial cable thiab coaxial cable. Baseband cable tsuas yog siv rau cov kis tau tus mob, cov ntaub ntawv tus nqi mus txog 10Mbps.
Coaxial cable (Coaxial Cable) yog hais txog ob tus neeg sib tham, thiab tus neeg xyuas pib thiab siv ntaub thaiv npog thiab qhia tib lub xwm txheej ntawm kab xov. Cov coaxial cable tshaj plaws muaj cov tooj hlau uas muaj hlau thaiv tawm ntawm cov khoom siv insulating, thiab sab nraud sab hauv txheej txheej yog lwm txheej ntawm cov lus sib txuas ntawm tus nplhaib thiab nws cov insulator, thiab tag nrho cov cable yog them los ntawm ib lub tsho ntawm cov tshuaj polyvinyl chloride los yog Teflon Cov
Coax cable (Coaxtal CabLe) nquag siv rau hauv cov cuab yeej thiab cov khoom siv ntawm qhov kev txuas, lossis siv nyob rau hauv lub npav sab saum toj. Coaxial cable center axis yog ib txoj hlua tooj hlau, ntxiv rau txheej txheej insulating khoom, hauv txheej txheej ntawm cov khoom siv insulating yog surrounded by hollow cylindrical mesh copper conductor qhwv, txheej txheej sab nraud yog txheej txheem thaiv tsev. Piv nrog rau nkawm twisted, coaxial cable tiv thaiv kev cuam tshuam kev ua tau zoo, shielding kev ua tau zoo, kis cov ntaub ntawv stability, tus nqi yog pheej yig, thiab nws tsis txuas nrog hub los yog hloov tau siv.
Cov kab hluav taws xob feem ntau yog ua los ntawm ob peb los yog ob peb pawg ntawm cov xov hlau tsawg kawg yog ob zaug uas muaj kab txuas zoo li cable, txhua pawg nyias muaj nyias ntawm ib leeg, thiab feem ntau nyob ib nrab chaw, tag nrho cov hnab sab nraud nrog lub qhov siab Insulated npog. Tshaj tawm hauv huab cua lossis hauv av, su dej, rau kev sib txuas lus los yog kev siv hluav taws xob.
