Kaboolka Cat waxaa laga heli karaa dhigashada computer network connection

Bandwidth-ka kabelada Cat waxay u taagantahay midabka sauraha oo kala wataan kama jirin dhaafadda iyo xadida ee si sax ah u dhaafid in ay la qeybinayo, oo loo qiimeeyaa megahertz (MHz), waxayna khaireysaa xariiqa soo saarida shakkada. Cat5e, taasoo ah jajabka ugu horeysa ee shabakadaha dambe, waxay siinaya bandwidth 100 MHz, oo kushaqaaleya Ethernet 1 Gbps - wana caawin guriga iyo shirkadaha yar ee ay u baahan yihiin in ay siin doonto, kala saarid shakada, iyo web browsing. Cat6 waxay kor u qaadaya bandwidth-ka 250 MHz, siinaya xariiqa 10 Gbps oo dhammaan laba meteeri oo fudud; midabka sauraha sare waxay kuu ogolaanayaa in ay kala wadaan shakada badan oo kala duwan, taasoo muhiim ah ee ay u baahan yihiin bandwidth-ka badan sida isdhaafadda video ee 4K ama kala saarid database gaaban oo offices. Cat6a waxay siinaya bandwidth 500 MHz, oo kushaqaaleya 10 Gbps oo dhammaan 100 meteer ee caadiga ah, taasoo leh midabka ugu badan ee shabakadaha shirkada ee ay u baahan yihiin kabelada badan. Cat7 iyo Cat7a waxay siinaya 600 MHz iyo 1000 MHz, oo kala saarid 10 Gbps oo dhammaan 100 meteer iyo 40 Gbps oo dhammaan laba yar (haddii aad ugu yareysid 50 meteer ee Cat7a), wana caawin data centers ee ay leeyihiin joogga sare. Cat8, taasoo ah caadiga ugu sareysa ee la xiriira, waxay leeyihiin bandwidth 2000 MHz, siinaya 40 Gbps oo dhammaan 30 meteer iyo 25 Gbps oo dhammaan 100 meteer, oo laa soo saaray si ay u kushaqaaleeyaan isku xirka server-ka iyo switch-ka. Bandwidth waxaa qarin sababta kala duwan sida dheererkii kabelka - dhaafadda iyo xadida ee ay kala wadaan waa in ay kordhantahay, waxayna khaareynaya bandwidth-ka xaqiijiyay; kabelada Cat aan la xidhi (UTP) waxay leeyihiin arrintii EMI ee sare ee ay kala wadaan marka ay kordhantahay sauraha (STP/FTP) ee la xidhiyey. Iyada oo isticmaale, in ay kordhantahay bandwidth-ka iyada oo leh waxay muhiimahay: in ay kordhantahay (tusaale, Cat8 ee isticmaalka guriga) waxay ku daray xaddi oo aan faa'iido lahayn, haddii kama kordhantahay (tusaale, Cat5e ee shabakada 10 Gbps) waxay abuuri kartaa xadka qaldan.
