Rau kev ua tus qauv miv 5 kab , koj yuav xav npaj cov xim-coded cov hlau hauv ib yam xaj ntawm ob qhov kawg. Nws yeej tsis teeb meem uas xaj koj muab cov xim rau hauv, tsuav yog nws zoo ib yam ntawm ob qho kawg. Yog tias koj xav ua raws li lub rooj sib tham nrov siv "568B" xaj.
Ntawm no, qhov kev txiav txim dab tsi ua Ethernet xaim mus rau hauv?
Technically, koj ua tau muaj cov cov hlau hauv ib qho xaj koj xav tau ntev npaum li ob qhov kawg yog wired tib yam. Txawm li cas los xij, Ethernet cables muaj cov qauv rau cov ib ntus ntawm kab hluav taws xob Lub npe hu ua T-568A thiab T-568B. Qhov txawv ntawm ob yog cov txiv kab ntxwv thiab ntsuab khub ntawm cov hlau hloov.
Tsis tas li ntawd, nws puas muaj teeb meem dab tsi xim kuv Ethernet cable yog? Koj tuaj yeem so kom paub tseeb tias koj tuaj yeem siv txhua yam xim Ethernet cable . Cov tsuas caveat ntxiv yuav yuav kom koj ua tsis yuav Crossover kab , cov no yog siv los txuas ob lub khoos phis tawj ua ke yam tsis siv lub router, lawv ib txwm tshaj tawm kom meej meej raws li Crossover thiab nws. yuav yuav nyuaj rau yuav ib qho yuam kev.
Yog li ntawd, cov xov hlau twg siv hauv Ethernet cable?
Kev lees paub rau lub dav hlau RJ45 data kab peb siv los txuas computers rau a Ethernet hloov yog ncaj-los ntawm kab . Raws li tau hais los saum no, RJ45 kab siv 2-pairs xwb cov hlau : Txiv kab ntxwv (pins 1 & 2) thiab Ntsuab (pins 3 & 6). Pins 4, 5 (Xiav) thiab 7, 8 (xim av) tsis yog siv.
Puas yog Ethernet siv tag nrho 8 xov hlau?
Gigabit Ethernet tso cai rau kev hloov pauv hauv network mus txog 1.000 Mbps siv Tus qauv Cat 5 UTP (unshielded twisted khub) cabling. Ethernet Cat 5 cables muaj yim kab (plaub khub), tab sis nyob rau hauv 10BaseT thiab 100BaseT tus qauv (10 Mbps thiab 100 Mbps, feem) tsuas yog plaub (ob khub) ntawm cov no cov hlau yog tiag siv.
