Cov Ntaub Ntawv Chaw 10 Gigabit Ethernet Cabling Xaiv
Nrog rau txoj kev loj hlob hauv cov ntaub ntawv chaw throughput, kev siv thiab thov kom siab dua cov neeg rau zaub mov, chaw cia khoom thiab sib txuas tau kuj nce. Yog li ntawd, qhov kev nthuav dav ntxiv ntawm kev kub ceev Ethernet cov kev daws teeb meem, tshwj xeeb tshaj yog 10 thiab 40 Gigabit Ethernet tau txuas ntxiv. Txog 10 Gigabit Ethernet kev daws teeb meem, xaiv qhov tsim nyog 10-gigabit lub cev tawm yog qhov nyuaj, vim 10GbE tau muaj ob yam dav: kho qhov muag thiab tooj liab. Kab lus no yuav qhia ob qho tib si kho qhov muag thiab tooj liab cabling rau 10 Gigabit Ethernet.
Ob hom dav dav ntawm cov kab hluav taws xob muaj nyob rau: tib hom kab thiab muaj fiber ntau fiber ntau.
Ib hom Fiber (SMF), feem ntau nrog cov qhov muag teeb pom kev zoo ntawm kwv yees li 9 μm (microns), muaj cov qauv hluav taws xob tsawg dua li cov fiber ntau. Nws muaj peev xwm los txhawb kev ncua kev tsawg kawg 10 kis lus mev, nyob ntawm kev sib kis ceev, hloov pauv thiab tsis tau faib rau hauv cov hloov.
Multimode Fiber (MMF), nrog rau cov khoom siv hluav taws xob tsis xws li ntawm 50 μm lossis 62.5 μm, tuaj yeem txhawb qhov mus txog 600 meters, nyob ntawm kev sib kis ceev thiab cov khoom sib kis.
Thaum npaj cov phiaj xwm cov ntaub ntawv cabling qhov yuav tsum tau, nco ntsoov txiav txim siab tias qhov kev pabcuam lub neej nyob ntawm 15-20 xyoo tuaj yeem xav txog rau cov kab npib fiber ntau. Yog li lub cable xaiv yuav tsum txhawb nqa cov ntawv keeb kwm, cov ntaub ntawv tam sim no thiab tawm.
10GBASE-SR - chaw nres nkoj hom rau multimode fiber, 10GBASE-SR cable yog hom ntau tshaj rau fiber ntau optic 10GbE cable. Nws muaj peev xwm los txhawb SFP + txuas nrog kho qhov muag transceiver ntsuas rau 10GbE kis ceev. 10GBASE-SR cable yog hu ua "luv mus txog" fiber ntau rau cable.
10GBASE-LR - chaw nres nkoj hom rau ib hom fiber ntau, 10GBASE-LR cable yog "ntev mus txog" fiber ntau cable. Nws muaj peev xwm los txhawb nqa qhov txuas txuas ntev li 10 kis lus mev.
OM3 thiab OM4 yog multimode cables uas yog "laser optimized" thiab txhawb 10 daim ntaub ntawv siv. Qhov kis tau tus mob nyob deb li ntawm 300 m thiab 400 m feem.
Cov qauv sib txuas ntawm 10GbE tooj liab tooj liab muaj raws li hauv qab no:
10GBASE-CR - hom tooj liab ntau tshaj 10GbE cable, 10GBASE-CR cable siv txuas nrog SFP + txuas thiab nws tseem hu ua SFP + Direct Attach Copper (DAC). Qhov no haum rau tib daim ntawv txuas txuas thiab tsev nyob raws li cov xov hluav taws xob fiber ntau txuas nrog SFP + cov khoom sib txuas. Ntau lub vev xaib 10GbE lees txais cov xaim hluav taws xob nrog SFP + cov khoom sib txuas, uas txhawb nqa ob qho tib si tooj liab thiab fiber ntau cov xaim hluav taws xob.
Passive thiab Active DAC - kev sib txuas tooj liab sib txuas yog tshwm sim nrog ntau yam cuam tshuam. Raws li cov kev hloov chaw nce siab, passive tooj liab tsis muab qhov kev ncua deb xav tau thiab coj mus ntau qhov chaw lub cev. Yog li kev lag luam tau hloov mus rau ib qho kev ua haujlwm tooj liab sib cuam tshuam rau kev sib txuas ceev dua. Kev sib txuas tooj liab txuas ntxiv nrog rau cov khoom siv uas ua kom lub teeb liab, txo lub suab nrov thiab ua haujlwm nrog cov ntsuas me me, txhim kho cov teeb liab nrug, cable yooj thiab cua.
10GBASE-T - 10GBASE-T cables yog Cat6a (qeb 6 txhawb ntxiv). Txhawb nqa qhov loj dua uas yuav tsum muaj rau kev xa xov 10GbE, qeb 6a yuav tsum ncav cuag qhov kev ncua deb ntawm 100 metres (330 taw). Cov kab hluav taws xob yuav tsum muaj ntawv pov thawj kom tsawg kawg 500 MHz kom ntseeg tau 10GBASE-T ua raws cai. Kab ntsig 6 kab yuav ua haujlwm nyob rau hauv 10GBASE-T xa mus txog 55 metres (180 ko taw) nyob ntawm qhov zoo ntawm kev teeb tsa. Qee qhov txuas ntawm 10GbE txuas rau 10GBASE-T (RJ45) cov khoom txuas.
Yuav xaus cov luv luv, tam sim no feem ntau hom 10GbE cables siv SFP + cov khoom sib txuas.
Rau cov chaw nyob tsis ntev, xws li tsis pub dhau lub khib lossis mus rau qhov chaw ze, siv DAC nrog SFP + cov khoom sib txuas, tseem hu ua 10GBASE-CR.
Rau cov khoom nruab nrab ntawm qhov nruab nrab, siv cov laser ua kom zoo rau multimode fiber ntau cables, ob qho tib si OM3 lossis OM4, nrog SFP + cov khoom sib txuas.
Rau cov chaw nyob ntev, siv ib hom kab hluav taws xob fiber ntau cov kab txuas, tseem hu ua 10GBASE-LR.
