Twisted Pair Cable Hom: Kawm txog ntau hom

Twisted khub cable yog ib hom kev xaim siv hauv kev sib txuas lus thiab khoos phis tawj. Lawv muaj ib khub ntawm insulated tooj liab xov hlau twisted ua ke kom txo tau electromagnetic cuam tshuam. Muaj ntau ntau hom twisted khub cable, txhua tus muaj nws tus kheej cov yam ntxwv thiab kev siv.

Ib qho ntawm feem ntau sib tw twisted khub cable yog unshielded twisted khub (UTP) cable. Hom kab no tau siv dav hauv Ethernet thiab xov tooj. Nws yog tus nqi-zoo thiab yooj yim rau nruab, ua rau nws muaj kev xaiv nrov rau ntau daim ntawv thov. UTP cables tuaj nyob rau hauv ob peb pawg, xws li Cat 5e, Cat 6, thiab Cat 6a, txhua tus muab ntau theem ntawm kev ua tau zoo thiab bandwidth.

Lwm hom twisted khub cable yog shielded twisted khub (STP) cable. STP cables muaj kev tiv thaiv ntxiv los tiv thaiv kev cuam tshuam ntawm electromagnetic, ua rau lawv haum rau ib puag ncig uas muaj suab nrov hauv hluav taws xob. Lawv feem ntau siv nyob rau hauv kev lag luam ib puag ncig thiab thaj chaw uas yuav tsum tau muaj kev tiv thaiv ntxiv rau kev cuam tshuam.

Tsis tas li ntawd, muaj cov twisted khub tshwj xeeb uas tsim los siv rau sab nraum zoov, xws li sab nraum zoov twisted khub. Ua los ntawm cov ntaub ntawv uas tuaj yeem tiv taus ib puag ncig hnyav, cov kab hluav taws xob no tsim nyog rau kev teeb tsa sab nraum zoov, xws li txuas cov tsev lossis cov kev soj ntsuam sab nraum zoov.

Thaum xaiv qhov tseeb twisted khub cable rau ib daim ntawv thov tshwj xeeb, yam xws li ib puag ncig, kev xav tau bandwidth, thiab cov peev txheej ntawm kev cuam tshuam yuav tsum raug txiav txim siab. Rau kev ua tau zoo thiab txhim khu kev qha, nws yog ib qho tseem ceeb uas yuav tau xaiv qhov tsim nyog twisted khub cable hom rau koj qhov kev xav tau tshwj xeeb.

Hauv cov ntsiab lus, muaj ntau hom twisted khub cables, txhua tus tsim los ua kom tau raws li cov kev cai tshwj xeeb thiab kev siv. Txawm hais tias nws yog UTP, STP lossis sab nraum zoov twisted khub cable, kev nkag siab txog ntau yam sib txawv yog qhov tseem ceeb rau kev xaiv txoj cai cable rau ib lub network tshwj xeeb lossis kev sib txuas lus. Los ntawm kev txiav txim siab cov yam ntxwv tshwj xeeb ntawm txhua hom twisted khub cable, cov neeg siv tuaj yeem xyuas kom meej, cov ntaub ntawv xa mus tau zoo hauv lawv lub network.
