Kaboolka Cat waxaa laga heli karaa dhigashada computer network connection

Midabka cablada Ethernet waxaa isbedelaa midabna siin khaas, qiimaha, dhererka iyo arimaha kale ee ku xusan, taas oo muujinaya suurtogalka ee arrinka kala duwan ee shabakada. Cablada ugu taaban (UTP) sida Cat5e, lagu sameeyay si loo gaabo 1 Gbps ee 100 mitir, waa in la iibsado, qiimahooda waxaa ka yar in lahayd centiyo badan ilaa dollar khamyis mitir, taas oo leh midabka ugu wanaagsan ee shabakada guriga ama deegaanka yar. Qiimaha Cat6, lagu taagay 10 Gbps ee dhererka yar (55 mitir) iyo lagu soo saaray waxaad joojehay in la xidho khamiyiska, waa in la iibsado, waxaa qiimahooda 50% ilaa 100% ka badan Cat5e. Noocyo kale ee Cat6 ama Cat6a oo leh qalabka (STP ama FTP) ee leh qalabka loo soo saaray in la xidho EMI ee joogta ama joogta arrinka, waa in la iibsado, sababtaa in ay badan yihiin iyo in ay badan yihiin. Qiimaha Cat7 iyo Cat8, lagu sameeyay si loo gaabo 10 Gbps+ ee dhererka badan ama joogta sare, waxaa ay leeyihiin qiimaha sare, midabka ugu wanaagsan ee data centers ama shabakada joogta sare. Dhererka waa xal ka mid ah: cablada bulshada (100+ mitir) waxaa leeyihiin qiimaha khamiyiska khamiyiska mitirka, ka badan midabka hoos ee horay u dhacay. Mashruucu iyo is daboolinta (sida, in la xidho TIA/EIA) ayaa sidoo kale muujiya qiimaha - mashruucaadka bulshada ee leh is daboolinta jirka waxaa badan yihiin laakiin ay ugu bixiya awooda la aqbali karo. Dheeraad ah coaxial cablada, cablada Ethernet waxaa yar yihiin qiimaha ee ugu yar ee ugu yar ee ugu yar ee ugu yar ee data, laakiin noocyada joogta sare ee Ethernet waxaa ugu yar yihiin in ay dhici lahayd ama ka yar yihiin qiimaha ee cablada coaxial ee joogta dhexe ee qaar ka mid ah istimaalka.
