CAT5E network Cable yog dab tsi?
CAT5e network cable yog ib qho sib tw-pair cable siv rau kev sib txuas hauv computer nrog tus nqi sib kis ntawm 1000Mbps, uas feem ntau siv rau kev sib txuas hauv cheeb tsam hauv cheeb tsam (LAN) hauv tsev, chaw ua haujlwm, tsev kawm ntawv thiab lwm qhov chaw. Cov yam ntxwv tshwj xeeb yog raws li hauv qab no:
1. Tus nqi kis tau tus mob siab: CAT5e cable txhawb kev sib kis tus nqi mus txog 1000Mbps, uas yog 10 npaug siab dua CAT5 cables, thiab tuaj yeem siv rau kev siv network uas siv cov ntaub ntawv loj.
2. Twisted-pair qauv: CAT5e network cable txais cov qauv twisted-pair, uas tuaj yeem txo qhov tshwm sim ntawm cov teeb liab cuam tshuam. Nws muaj plaub khub ntawm cov xov hlau, txhua tus muaj xim sib txawv rau kev teeb tsa yooj yim.
3. Yooj yim rau nruab: CAT5e cable siv RJ45 connector: yooj yim rau nruab, ntsaws thiab ua si, haum rau sab hauv tsev luv luv cabling, thiab siv tau yooj yim.
4. Stable impedance: CAT5e cable yog ua los ntawm cov ntshiab tooj liab hlau nrog tshwj xeeb sab hauv qauv tsim, uas muaj peev xwm tswj tau cov stability ntawm kev twb kev txuas thiab kis tau tus mob thiab xyuas kom meej qhov zoo ntawm kev sib txuas lus network.
5. Zoo compatibility: CAT5e cable yog sib xws nrog CAT5 thiab yav dhau los cable specifications, thiab yuav siv tau raws li ib qho kev xaiv rau tes hauj lwm tshiab los yog ib tug upgrade rau cov tes hauj lwm uas twb muaj lawm.
Nws yuav tsum raug sau tseg tias CAT5e network cable muaj qhov sib kis tau zoo thiab tuaj yeem tiv thaiv kev cuam tshuam loj heev, qhov ntev ntev, qhov siab dua qhov hnav thiab tsim kua muag, thiab feem ntau yuav tsum tsis pub tshaj 100 meters. Tsis tas li ntawd, txij li kev teeb tsa tsis zoo xws li faus thiab khoov tuaj yeem cuam tshuam kev sib kis ntawm cov cables hauv lub network, nws yuav tsum ua raws li cov lus qhia tshwj xeeb thaum txhim kho lawv.
Qhov txawv
Muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm ntawm Qeb 5 thiab Qeb 6 network cables. Txawm hais tias Qeb 5 cables tuaj yeem txhawb Gigabit Ethernet, lawv qhov kev ua tau zoo tsuas yog suav tias tsuas yog txhawb nqa xwb. Hauv qhov sib piv, Qeb 6 cables tuaj yeem lav qhov kev khiav hauj lwm ceev ntawm Gigabit Ethernet, muab cov neeg siv nrog kev ruaj ntseg thiab kev sib txuas lus zoo dua. Qhov no txhais tau hais tias nyob rau hauv cov ntaub ntawv ntawm kev thauj khoom siab lossis cov ntaub ntawv loj xa mus, Qeb 6 cables tuaj yeem ua tau raws li qhov xav tau zoo dua thiab txo qis network qeeb thiab lagging tshwm sim.
Thib ob: cov yam ntxwv ntawm cov qauv
Ntxiv rau qhov kev ua tau zoo sib txawv, Qeb 5 thiab Qeb 6 network cables kuj txawv hauv cov qauv. Qeb 6 twisted-pair cable muaj cov cuab yeej zoo insulating nrog kev sib ntxiv ntawm cov pob txha hauv nws cov qauv. Nyob rau tib lub sijhawm, nws cov khoom siv hluav taws xob muaj lub taub loj dua, lub zog me me, thiab lub thickness ntawm sab nraud. Cov kev tsim kho no ua rau qeb VI network cable hauv kev tiv thaiv kev cuam tshuam ntawm kev sib txuas ntawm network cables kev ua tau zoo, txhim kho cov teeb liab kis tau zoo.
Thib peb: kis tau tus mob nrug thiab ceev
Hais txog kev sib kis deb thiab ceev, kuj tseem muaj qee qhov sib txawv ntawm ultra-tsib network cable thiab qeb rau network cable. Feem ntau hais lus, qhov kev ncua deb ntawm ultra-tsib network cable yog nyob rau hauv 100 meters, thaum kis tau tus mob nyob deb ntawm qeb rau network cable yuav ncav cuag 120-150 meters. Tsis tas li ntawd, Qeb 6 cables tau txhim kho lawv cov kev ua tau zoo nyob rau hauv cov nqe lus ntawm crosstalk thiab rov qab poob, ua rau muaj teeb meem tsawg attenuation thiab ceev ceev nyob rau hauv cov txheej txheem kis tau tus mob. Qhov no yog qhov tseem ceeb rau cov xwm txheej uas xav tau kev sib kis mus ntev lossis kev siv network ceev.
