Network cable-twisted khub
Lub network cable yuav tsum tau txuas rau ib cheeb tsam hauv cheeb tsam network. Cov kab hluav taws xob sib txuas hauv LAN feem ntau suav nrog cov kab sib tw twisted, coaxial cables, thiab optical cables. Twisted khub yog cov ntaub ntawv kis tau tus mob ua los ntawm ntau cov khub hlau. Nws cov yam ntxwv yog pheej yig, yog li nws yog dav siv rau cov kab xov tooj dav dav. Siv rau kev sib txuas nrog RJ45 siv lead ua taub hau.
Muaj ob hom: STP thiab UTP. UTP feem ntau yog siv.
Muaj ob tus qauv rau twisted khub txiav: T568A thiab T568B. Muaj ob txoj hauv kev tseem ceeb ntawm kev sib tw twisted: ncaj cable thiab hla cable. Txhua qhov kawg ntawm txoj kab ncaj nraim siv lead ua lub taub hau ua raws li tus qauv T568B. Muaj kev sib txuas lus ib-rau-ib qhov nruab nrab ntawm qhov sib txawv ntawm txhua qhov sib tw-pair hlau, thiab tib xim yog tuav nyob rau hauv cov grooves sib thooj ntawm ob qho kawg ntawm cov khoom siv lead ua. Nws yog tsuas yog siv los txuas rau qhov hloov pauv (lossis hub) qhov chaw nres nkoj ib txwm nrog qhov hloov pauv (lossis hub) chaw nres nkoj uplink, lossis hloov qhov chaw nres nkoj ib txwm txuas mus rau lub khoos phis tawj network. Qhov kawg ntawm lub taub hau siv lead ua ntawm crossover cable ua raws li 568A thiab lwm qhov kawg siv tus qauv 568B. Ntawd yog, A siv lead ua taub hau 1 thiab 2 sib haum rau B siv lead ua taub hau 3 thiab 6, thiab A siv lead ua taub hau 3 thiab 6 sib haum rau B siv lead ua taub hau 1 thiab 2. Nws yog siv rau cov chaw nres nkoj dav dav ntawm qhov hloov (los yog hub) thiab txuas. mus rau qhov chaw nres nkoj ib txwm lossis daim npav network ntawm qhov hloov pauv (lossis hub) txuas rau daim npav network.
Rau txoj kab kab rov tav txiav hauv txoj haujlwm cabling, GB 50312 lees txais T568B lossis T568A, tab sis tsis tuaj yeem nruab rau tib lub sijhawm, thiab feem ntau xaus nrog T568B.
