Nyob rau hauv lub era ntawm cov ntaub ntawv tawg, yuav luag txhua leej txhua tus yuav tsum tau nkag mus rau hauv internet, thiab yuav luag txhua qhov chaw yog nruab nrog lub network thiab lub network cable, tab sis tej zaum koj yuav tsis paub hais tias txawm lub network cable zoo li qub, muaj tiag tiag sib txawv pawg.Ntawm no, tsab xov xwm no yuav muab piv rau Cat5e (super 5) network cable, Cat6 (6) network cable, Cat6a (super 6) network cable thiab Cat7 (7) network cable, txhawm rau pab koj xaiv txoj cai network cable.
Network cable tseem hu ua network jumper thiab twisted khub, feem ntau yog siv nrog RJ 45 siv lead ua lub taub hau, vim nws pheej yig thiab siv dav hauv LAN, thiab network cable yog qhov nruab nrab kis tau zoo tshaj plaws hauv kev sib txuas.
Cat5e ua haujlwm tib yam li Cat6 network cable, ob qho tib si muaj tib hom RJ-45 ntsaws, thiab tuaj yeem ntsaws rau hauv ib qho Ethernet jack ntawm lub computer, router, lossis lwm yam khoom siv zoo sib xws.Txawm hais tias lawv muaj ntau qhov sib xws, lawv muaj qee qhov sib txawv, Cat5e network cable thov hauv Gigabit Ethernet, kis tau tus mob mus txog 100m, thiab tuaj yeem txhawb nqa 1000Mbps kis ceev.Cat6 network cables tuaj yeem muab kev sib kis ceev txog li 10 Gbps hauv 250 MHz bandwidth.Qhov kev ncua deb ntawm Cat5e network cable thiab Cat6 network cable yog 100m, tab sis thaum siv 10 GBASE-T daim ntawv thov, kev sib kis ntawm Cat6 network cable tuaj yeem ncav cuag 55 m.Qhov sib txawv tseem ceeb ntawm Cat5e thiab Cat6 yog kev thauj mus los.Lub Cat6 cable muaj qhov sib cais sab hauv uas txo cov kev cuam tshuam lossis sib cuam tshuam sib cuam tshuam (Tom ntej).Nws kuj tseem txhim kho distal crosstalk (ELFEXT) dua li Cat5e cable, thiab muaj qis ncha poob thiab qhov poob.Yog li, Cat6 cable muaj kev ua tau zoo dua.Cat6 network cable txhawb kev sib kis ceev txog li 10G thiab muaj qhov zaus bandwidth txog li 250 MHz, thaum Cat6a network cable tuaj yeem txhawb nqa qhov zaus bandwidth txog li 500 MHz, ob npaug ntawm Cat6 network cable.Lub Cat7 network cable txhawb lub zaus bandwidth txog li 600 MHz, thiab tseem txhawb 10 GBASE-T Ethernet.Tsis tas li ntawd, Cat7 network cable zoo heev txo cov suab nrov crosstalk piv rau Cat6 thiab Cat6a network cable.Cat5e Network cable, Cat6 cable thiab Cat6a cable muaj RJ 45 connector, tab sis cov connector ntawm Cat7 cable yog tshwj xeeb tshaj yog, nws connector hom yog GigaGate45 (CG45).Tam sim no, Cat6 cable thiab Cat6a cable tau pom zoo los ntawm TIA / EIA cov qauv, tab sis Cat7 cable tsis tau.
Cat6 network cable thiab Cat6a network cable yog tsim rau siv hauv tsev.Hloov chaw, yog tias koj tab tom khiav ntau daim ntawv thov, koj yuav tsum xaiv Cat7 network cable zoo dua, vim tias nws tsis tuaj yeem txhawb nqa ntau daim ntawv thov, tab sis kuj muaj kev ua tau zoo dua.
Cov saum toj no yog ib qho kev piav qhia luv luv ntawm qhov sib txawv ntawm cov kab hluav taws xob sib txuas.Cov khoom lag luam network ntawm Shenzhen HDV Phoelectron Technology Co., Ltd. yog txhua yam khoom siv tsim nyob ib puag ncig cov khoom lag luam, suav nrogONUseries /OLTseries / optical module series / transceiver series thiab lwm yam.Txhawm rau tsim cov khoom siv network zoo tshaj plaws, peb lub tuam txhab tau nruab nrog pab pawg tshawb fawb thiab kev txhim kho, muab cov neeg siv khoom nrog cov kev pabcuam zoo tshaj plaws, txais tos thov cov neeg ua haujlwm kom nkag siab txog peb cov khoom.
