Ethernet cable yog lub hauv paus ntawm niaj hnub wired network. Tsuas yog xaiv qhov tsim nyog network cable tuaj yeem ua kom ruaj khov thiab siab - cov ntaub ntawv xa mus ceev. Peb yog cov chaw tsim khoom ntawm cov xov hlau thiab cables. Cov lus qhia no yuav qhia meej txog cov ntsiab lus tseem ceeb ntawm lub network cable, suav nrog cov khoom siv hluav taws xob, cov qauv kab hluav taws xob, hom kev tiv thaiv, thiab cov ntawv thov tiag tiag. Peb cia siab tias yuav pab tau koj xaiv ib lub tswv yim network cable nrog tus nqi siab thiab txhim khu kev qha zoo.
Tus coj
Oxygen dawb tooj liab: Qhov no yog cov khoom siv zoo tshaj plaws uas tsis muaj kev tiv thaiv, siab teeb liab kis tau tus mob thiab poob qis.
Copper clad aluminium: lub hom phiaj yog txo tus nqi. Lub hauv paus yog aluminium thiab tooj liab txheej. Kev ua tau zoo tsis zoo li cov tooj liab ntshiab, nrog kev ua haujlwm siab dua thiab cov teeb liab tseem ceeb attenuation nyob rau qhov ntev.
Specification
Common specifications yog 23AWG, 24AWG, thiab 26AWG.
Hla Separator
Ua los ntawm cov yas tawv tawv, nws lub cev sib cais plaub qhov sib tw ua ke kom txo tau cov lus sib txuas ntxiv thiab ua kom cov teeb liab zoo thaum lub sijhawm siab - kis tau tus mob.
Tensile Strength Member
Galvanized steel hlau los yog fiber ntau xov ntxiv zog cable, tiv thaiv kev tawg thaum rub. Tsis yog txhua tus Ethernet cables muaj, tab sis siab - cov khoom zoo feem ntau suav nrog nws.
Rwb thaiv tsev
Cov txheej txheej rwb thaiv tsev feem ntau yog PVC lossis PE Cov qauv kev teeb tsa suav nrog kev sib tw ua ke los ua plaub khub ntawm "twisted khub". Txhua khub muaj cov kab hluav taws xob sib txawv ntawm cov xim sib txawv ua ke (piv txwv li, txiv kab ntxwv dawb / txiv kab ntxwv, xiav dawb / xiav, ntsuab dawb / ntsuab, xim av dawb / xim av).
Rwb thaiv tsev Barrier Txheej
Ib txheej yas pob tshab uas ntxiv cov plaub sib tw twisted los ntawm cov hlau thaiv, tiv thaiv kev cuam tshuam ntxiv los ntawm kev sib cuag ncaj qha.
Tiv thaiv
Aluminium ntawv nyiaj + hlau woven mesh (los yog ib qho txhuas ntawv ci) tiv thaiv sab nraud electromagnetic cuam tshuam.
Outer Jacket
PVC (Polyvinyl Chloride) lossis Cov Khoom Siv Hluav Taws Xob Tsis Muaj Halogen (LSZH yog ib puag ncig zoo dua qub, muaj cov nplaim hluav taws zoo, thiab feem ntau siv rau hauv siab -kawg tej yaam num) los tiv thaiv cov qauv sab hauv, muab hnav tsis kam, corrosion resistance, thiab tensile zog.
Qhov hluav taws xob
Ethernet cables xa cov kab hluav taws xob tsawg-voltage signals (feem ntau hauv qab 12V, qis dua cov hluav taws xob ntau), siv rau cov ntaub ntawv teeb liab kis, tsis yog hluav taws xob xa mus.
Kev siv Scenarios
Tsev Neeg: network socket thaiv hauv chav nyob thiab chav pw, txuas router thiab cov cuab yeej ntse (computer, TV, koob yees duab, thiab lwm yam).
Chaw Ua Haujlwm: network cabling nruab nrab ntawm chaw ua haujlwm, chav neeg rau zaub mov thiab cov servers kom ntseeg tau siab -kev sib txuas ceev ntawm ntau yam khoom siv.
Kev lag luam / kev lag luam: WiFi kev pab them nqi hauv khw muag khoom, Hoobkas saib xyuas tes hauj lwm, cov ntaub ntawv chaw neeg rau zaub mov pawg kev sib txuas, thiab lwm yam.
