Thaum nws los txog rau lub network cabling, thaum nws los ntawm lub network txee, peb tsis yog tshiab. Kev faib tus ncej, jumper ncej, tus neeg saib xyuas hlau, thaum lawv siv, lawv qhov tseeb.
Kev siv thiab kev siv tau tsuas yog teeb tsa raws li tus naj npawb ntawm cov qhab nia hauv lub network lossis tus naj npawb ntawm cov qhab nia ntawm lub hauv av (thiab cov plag tsev uas nyob ib sab, nyob ntawm seb cov kab ke kev teeb tsa tau tsim li cas). Cov vaj tse sib txawv, cov kab ke sib txawv, cov kab sib faib cov khoom siv tseem ceeb yuav txawv. Piv txwv li, lub tsev tsuas muaj plaub txheej, chav tsev cov khoom tseem ceeb yog teem rau thawj chav tsev, thiab lub network cov ntsiab lus ntawm txhua cov plag tsev nkag mus hauv chav siv cov khoom siv, tom qab ntawd tus naj npawb ntawm cov ntas sib faib yog sib npaug nrog tus naj npawb ntawm txhua qhov network cov ntsiab lus / kev faib khoom ncej cov kab (24 chaw nres nkoj, 48 chaw nres nkoj, thiab lwm yam) ntawm lub tsev, ntxiv rau qee yam npoo; yog tias lub tsev muaj cuaj chav tsev, thiab chav siv cov khoom tseem ceeb tau teeb rau hauv chav plaub, tom qab ntawd kom tsis txhob muaj cov cab hluav taws xob ntev ntev, nws yuav teeb rau txhua chav tsev muaj sub chav siv thiab cov cuab yeej sib pauv hloov. Tom qab ntawd cov faib kab nruab nrab ntawm cov cuab yeej tseem ceeb yog sib npaug nrog cov naj npawb ntawm cov qhab nia ntawm chav tsev thib plaub / tus naj npawb ntawm cov thawv faib (24 chaw nres nkoj, 48 chaw nres nkoj, thiab lwm yam).
Qhov chaw faib khoom yog qhov tseem ceeb tshaj plaws hauv kev tswj kab ke, thiab nws yog lub hub kom paub qhov kev sib txuas ntawm cov kab nruab nrab kab rov tav thiab cov kab hluav taws xob kab rov tav. Panels feem ntau yog nruab rau hauv txee lossis hauv phab ntsa. Los ntawm kev teeb tsa ntawm cov khoom siv ntxiv, cov kab xa tawm tuaj yeem ua tau raws li qhov kev xav tau ntawm UTP, STP, coaxial cable, optical fiber, audio thiab video. Twisted khub faib ncej thiab optical faib ncej yog nquag siv nyob rau hauv network engineering.
