UTP vs STP Cables: Dab tsi yog qhov txawv ntawm lawv?
Twisted khub network cables yog dav siv nyob rau hauv cov ntaub ntawv kis, tshwj xeeb tshaj yog thoob plaws zoo heev. Cov twist hauv cov xaim cancels tawm txhua qhov sib txawv ntawm qhov teeb meem uas yuav tsim tau hauv lub thaiv. Muaj ob hom kab sib tw, STP thiab UTP. Cov S stands rau Shielded, tus U stands rau Unshielded, thiab TP sawv ntsaws rau nkawm ob leeg. Ib qho ntawm qhov ntawd, puas muaj lwm yam txawv ntawm lawv? Ntawm no yuav tham txog UTP vs STP cables los ntawm lawv cov ntsiab lus thiab daim ntaub ntawv.
UTP vs STP: Tus Kab Mob UTP Yog Dab Tsi?
Unshielded Twisted Pair (UTP): UTP yog cov xov tooj tooj liab, tau txais los ntawm kev hu xov tooj, uas yog siv rau cov ntaub ntawv nce siab dua, thiab yog muaj qhov tseeb qhov txuj ci rau kab rov tav, qhov sib txuas ntawm, thiab nrog, qhov hluav taws xob thiab txiav nyob rau hauv kev sib txuas lus txee.
Ib Twisted Pair yog ob kab hlau nrig, nrog diameters ntawm 0.4 -0.8 hli twisted ua ke thiab qhwv nrog ib tug yas txheej. Txoj kev sib tw ua kom lub suab qeeb zog ntawm qhov hluav taws xob thiab txo qhov kev ua yuam kev tsawg (BER) ntawm cov ntaub ntawv xa tawm. Ib tug UTP cable muaj los ntawm 2 txog 4200 cov khub.
Qhov zoo ntawm UTP tej zaum yuav txawv ntawm xov tooj-hlau xaim mus rau kev lag luam uas tsis tshua muaj siab ceev. Lub cable muaj plaub khub ntawm cov nyob hauv lub tsho loj. Txhua tus khub yog sib tw nrog ntau tus twists ib nti los pab tshem tawm txoj kev cuam tshuam ntawm cov uas nyob ib sab thiab lwm yam khoom siv hluav taws xob. Lub koom haum EIA / TIA (Electronic Industry Association / Telecommunication Industry Association) tau tsim cov qauv ntawm UTP thiab tau qhia txog 5 yam ntawm cov xov hlau.
Pawg Cov Neeg Uas Tsis Muaj Feem Xyuam Khuam Siv:
* Qeb 1 Voice Xwb (Xov Tooj)
* Qeb 2 Cov Ntaub Ntawv rau 4 Mbps (Tham Hauv Zos)
* Qeb 3 Cov Ntaub Ntawv rau 10 Mbps (Ethernet)
* Qeb 4 Cov Ntaub Ntawv rau 20 Mbps (16 Mbps Token Nplhaib)
* Qeb 5 Cov Ntaub Ntawv rau 100 Mbps (Taus Ethernet)
* Qeb 5e Cov Ntaub Ntawv rau 1000 Mbps (Gigabit Ethernet)
* Qeb 6 Cov Ntaub Ntawv rau 10000 Mbps (10Gigabit Ethernet)
* Qeb 6a Cov Ntaub Ntawv rau 10000 Mbps (10Gigabit Ethernet)
* Cat7 cable Cov ntaub ntawv mus rau 10000 Mbps (10Gigabit Ethernet)
Ib qhov txawv ntawm UTP txawv pawg yog qhov ceev ceev ntawm kev sib tw ntawm cov khub tooj liab. Lub tighter twisting, qhov siab dua tus txhawb nqa tus nqi thiab qhov ntau dua tus nqi ntawm ib tug ko taw. Yuav zoo tshaj plaws ntawm ethernet cables koj tuaj yeem them taus; feem ntau cov tsev kawm ntawv yuav Qeb 3 los sis Qeb 5. Qeb 5 cable yog qhov pom zoo. Kev sib txawv ntawm Cat5, Cat5e, Cat6, Cat6, Cat7, Cat7, Cat7, Cat8, Cat9, Saib read ntawm Ethernet Cables Cat5, Cat5e thiab Cat 6 thiab Cat6 vs Cat7 vs Cat8: Dab tsi yog qhov txawv?
Yog tias koj tsim tus 10 Mbps Ethernet network thiab xav tias qhov kev txuag nqi ntawm kev yuav khoom Qiv 3 xauv es tsis txhob Qib 5, nco ntsoov tias Qeb 5 yuav muab ntau chav "chav loj tuaj" raws li kev sib kis yees technologies nce. Ob qho tag nrho qeb 3 thiab qeb 5 UTP muaj ntau qhov ntev ntev txog 100 meters. Nyob rau hauv Florida, Tshooj 5 cable yog yuav tsum tau rau cov nyiaj pab ntxiv. 10BaseT hais txog cov lus qhia rau cov hlua khau uas tsis tau sib tw (qeb 3, 4, lossis 5) nqa cov teeb meem Ethernet.
UTP vs STP: Dab Tsi Yog Kab Mob STP?
Cov kab mob shielded Twisted Pair (STP): STP yog hnyav dua thiab nyuaj rau kev tsim khoom, tab sis nws tuaj yeem txhim kho qhov taw qhia cov paib hauv ib txoj kab ke sib kis Kev sib ntsev muab qhov khoo ntawm qhov chaw khaus thiab cov kab ntawm ib tus neeg coj. Sib nqus cov kauj nrhau nyob ib ncig ntawm lwm cov neeg hnyav-uas yog neeg taug kev thiab ib ncig ntawm cov hluav taws xob loj. Ntau qib ntawm tooj liab cables muaj, nrog Qib 5 yog qhov zoo tshaj plaws thiab kim tshaj plaws.
Qib 5 tus qauv tooj liab, tsim nyog siv rau hauv 100-Mbps cov ntawv thov, muaj twists ib ntiv me tshaj li qib. Cov twists ntau dua ib ntu txhais tau tias ntau tus taw tes ntawm cov tooj liab hlau siv los ua ib txoj hlua cab khiav, thiab tooj liab ntau txhais tau tias ntau dua.
Nyob rau hauv cov nqe lus ntawm kev siv, UTP yog cov ntau dua thiab nrov cabling uas yog siv nyob rau hauv ntau lub tsev, chaw ua hauj lwm, thiab txawm nyob rau hauv loj cov lag luam los ntawm nws qis tus nqi. STP feem ntau siv los ntawm cov tuam txhab loj hauv cov ntawv siab uas yuav tsum tau siv ntau tshaj plaws bandwidth. STP cables tseem siv nyob rau hauv cheeb tsam sab nraum qhov chaw uas cov cables raug rau cov khoom thiab cov khoom tsim rau neeg thiab cov khoom siv uas yuav ua rau muaj kev cuam tshuam ntxiv. Cov qauv zoo ntawm qhov no yuav yog cov xov tooj hauv internet / hauv internet uas khiav tawm hauv koj lub tsev mus rau ntawm lub box, mus rau cov chaw ua haujlwm ntawm koj tus kws kho mob lossis ISP.
Rau feem ntau cov kev siv, nws tsis tshua tseem ceeb yog koj siv STP los yog UTP thaum ob leeg yuav ua tau zoo. UTP yog qhov kev xaiv ntau dua li nws yog pheej yig thiab yooj yim dua los nrhiav hauv feem ntau ntawm cov khoom siv computer khoom muag.
UTP vs STP Cables Qhia tawm:
• STP cables raug thaiv thaum UTP cables tsis muaj leej twg txaj muag
• Cov kab mob STP ntau dua kev tiv thaiv thiab suab nrov tshaj UTP cables
• Cov kab mob STP zoo dua rau qhov muab qhov qhwv ntsej muag ntau tshaj piv rau UTP cables
• STP cable nqi ntau tshaj ib lub 'meter' piv rau UTP cables
• Cov kab mob STP muaj hnyav ib lub 'meter' piv rau UTP cables
• UTP cables muaj ntau dua nyob hauv SOHO tes hauj lwm thaum STP siv ntau daim ntawv thov siab.
