Chingwe cha Cat5e motsutsana ndi Cat6 motsutsana ndi Cat7 Lan

Cat5e ndi Cat6 zimagwira ntchito mofanana, zili ndi cholumikizira cha RJ-45 chofanana, ndipo zimatha kulumikiza mu jack iliyonse ya Ethernet pa kompyuta, rauta, kapena chipangizo chofanana. Ngakhale zili ndi zofanana zambiri, zili ndi kusiyana kwina, monga momwe zasonyezedwera patebulo lotsatirali:

Monga momwe zikuonekera patebulo, chingwe cha netiweki cha Cat5e chimagwiritsidwa ntchito mu gigabit Ethernet, mtunda wotumizira uthenga ukhoza kufika pa 100m, ukhoza kuthandizira liwiro la kutumiza uthenga la 1000Mbps. Chingwe cha Cat6 chimapereka liwiro la kutumiza uthenga mpaka 10Gbps mu bandwidth ya 250MHz.

Cat5e ndi Cat6 zonse zili ndi mtunda wa ma transmission wa 100m, koma ndi 10Gbase-T, Cat6 imatha kuyenda mpaka 55m. Kusiyana kwakukulu pakati pa Cat5e ndi Cat6 ndi magwiridwe antchito a mayendedwe. Mizere ya Cat6 ili ndi cholekanitsa chamkati kuti chichepetse kusokonezeka kapena njira yolowera pafupi (NEXT). Amaperekanso njira yabwino yolowera kutali (ELFEXT) komanso kutayika kochepa kobwerera ndi kutayika kolowera poyerekeza ndi mizere ya Cat5e.

Monga momwe zasonyezedwera patebulo, Cat6 imatha kuthandizira liwiro lotumizira maginito mpaka 10G komanso bandwidth ya maginito mpaka 250MHz, pomwe Cat6a imatha kuthandizira bandwidth ya maginito mpaka 500MHz, yomwe ndi kawiri kuposa Cat6. Chingwe cha Cat7 chimathandizira bandwidth ya maginito mpaka 600MHz komanso chimathandizira Ethernet ya 10gbase-t. Kuphatikiza apo, chingwe cha Cat7 chimachepetsa kwambiri phokoso la crosswalk poyerekeza ndi Cat6 ndi Cat6a.

Cat5e, Cat6, ndi Cat6a zonse zili ndi zolumikizira za RJ45, koma Cat7 ili ndi mtundu wapadera wolumikizira: GigaGate45(CG45). Cat6 ndi Cat6a pakadali pano zavomerezedwa ndi miyezo ya TIA/EIA, koma osati Cat7. Cat6 ndi Cat6a ndizoyenera kugwiritsidwa ntchito kunyumba. M'malo mwake, ngati mukugwiritsa ntchito mapulogalamu opitilira amodzi, Cat7 ndiye chisankho chabwino kwambiri chifukwa sichimangothandizira mapulogalamu opitilira amodzi okha, komanso chimapereka magwiridwe antchito abwino.
