Los ntawm kev yuav SFP + DAC high-speed cable los ntawm cov chaw tsim khoom lag luam txhim khu kev qha, koj tuaj yeem yuav cov khoom lag luam zoo thiab txuag nyiaj tib lub sijhawm.
(3) Puas tuaj yeem siv SFP + DAC high-speed cable hauv SFP chaw nres nkoj?
SFP + DAC high-speed cable tuaj yeem rov qab-tshaj nrog SFP cov chaw nres nkoj kom ntseeg tau tias kev ua haujlwm ntawm lub network. Txawm li cas los xij, SFP DAC high-speed cable tsis sib xws nrog SFP + chaw nres nkoj. SFP DAC high-speed cable tuaj yeem txuas rau hauv SFP + chaw nres nkoj, tab sis tsis yog rau 10G cov ntaub ntawv hloov pauv.
Kuv yuav ua li cas xa SFP + DAC high-ceev cables nyob rau hauv ib tug data center?
SFP + DAC high-ceev cable yog ib qho kev sib txuas cable rau kev paub txog kev sib txuas lus ceev ceev tshaj qhov luv luv. Nws yog dav siv nyob rau hauv cov ntaub ntawv chaw zov me nyuam thiab server chav. Txhawm rau ua kom koj SFP + DAC kev kub ceev cable ua haujlwm, ntawm no yog yuav ua li cas xa SFP + DAC kev kub ceev cable hauv koj qhov chaw khaws ntaub ntawv.
(1) xam qhov ntev ntawmSFP + DAC high-speed cableua ntej
Thaum deployingSFP + DAC high-speed cablenyob rau hauv ib qho {{0}}inch, 45RU txee, nws yog conservatively kwv yees tias lub cable ntev ntawm sab saum toj mus rau hauv qab ntawm lub txee yog kwv yees li 7 ko taw (2.1m) thiab cov cable ntev ntawm ob qhov chaw nres nkoj nyob ib sab. yog kwv yees li 1.5 feet ({15}}.45m). Yog tias lub txee muaj ob lub ToR keyboards thiab 20 2U SFP + NIC servers, qhov siab tshaj plaws uas yuav tsum tau muaj SFP + DAC high-speed cable yuav tsum yog 2.1+2 × 0.45≈3m. Ntawm no, koj tuaj yeem yuav 3m SFP + DAC high-speed cable.
(2) Tsis txhob tshaj lub vojvoog dabtsi yog khoov ntawm SFP + DAC high-speed cable
Thaum siv SFP + DAC kev kub ceev cable, xyuas kom tseeb tias lub cable nyob rau hauv qhov tsawg kawg nkaus dabtsi yog khoov vojvoog qauv. Txhua SFP + DAC kev kub ceev cable muaj qhov sib txawv yam tsawg kawg nkaus dabtsi yog khoov vojvoog raws li lub teb chaws USA hlau ntsuas.
(3) Tiv thaiv koj SFP + DAC high-speed cable nrog cov cuab yeej tswj
Txhawm rau tiv thaivSFP + DAC kev kub ceev cableslos ntawm sagging vim load ntau dhau, nws yog ib qho tsim nyog yuav tsum tau siv cov kev tswj hwm cable lossis cov cuab yeej daws kev ntxhov siab. Cov cuab yeej pab daws kev ntxhov siab tuaj yeem tsis tsuas yog xyuas kom meej tias lub vojvoog dabtsi yog khoov ntawm SFP + DAC high-speed cable yog khaws cia nyob rau hauv ib txwm muaj, tab sis kuj pab txhawb txoj hauv kev cable kom muaj kev sib haum xeeb thiab kev sib raug zoo. Nyob rau tib lub sijhawm, cov cuab yeej tswj hwm cable xws li cov hlua khi tuaj yeem siv los khi cov hlua hluav taws xob ceev ceev rau cov cuab yeej kev ntxhov siab, uas yog qhov tsim nyog rau kev ruaj ntseg cable.
