Lub hom phiaj tseem ceeb ntawm 50 ohm coaxial kab yog kis cov ntaub ntawv cov cim hauv ob txoj kev sib txuas lus. Cov ntawv thov piv txwv suav nrog: txuas xov kab thaum computer tsim Ethernet, wireless network kav hlau txais xov feeders, GPS kav hlau txais xov feeders, thiab lub xov tooj txawb xov tooj. Cov xov tooj sib dhos cable cov khoom tau teev nyob hauv seem no npog feem ntau siv RG series coaxial cables thiab cov khoom sib txuas rau cov ntawv thov saum toj no.
Lub hom phiaj tseem ceeb ntawm 75 ohm coaxial cable yog xa cov cim video. Ib daim ntawv thov raug dua yog kis cable TV teeb liab, yog li nws qee zaum hu ua" teeb liab pub", thiab nws feem ntau yog nruab nrog F-type connector. Lwm cov ntawv thov siv ua kab ke video kis kis rau cov twj tso tawm, xws li txuas cov DVD, tso video, thiab tsav. Lub sijhawm no, nws yog hu ua audio thiab video (A / V) kab, uas feem ntau nruab nrog BNC thiab RCA txuas. Ntawm cov saum toj no ob daim qauv piv txwv, RG59 thiab RG6 coaxial cables yog qhov feem ntau siv. Ntawm lawv, RG59 suav nrog RG59B / U (ib leeg-strand center hlau) thiab RG59A / U (cov khoom siv ntau lub nruab nrab xaim hlau). Cov xov tooj sib dhos khoom lag luam nyob hauv seem no npog tag nrho cov kev qhia tshwj xeeb uas tsim nyog rau ob daim ntawv thov no.
Ntawm txhua hom kev sib txuas coaxial, BNC yog qeb tshwj xeeb ntau, muab faib ua ob qhov kev cuam tshuam ntawm 50 ohm thiab 75 ohm. Txoj hauv kev kom paub qhov txawv ntawm ob qhov kev qhia tshwj xeeb no yooj yim heev, raws li pom hauv daim duab: 50 ohm BNC txuas muaj lub qhov hluav taws xob ntawm qhov sib cuam tshuam, thaum 75 ohm tsis muaj qhov tsis muaj qhov thaiv.
