(1) Yuav ua li cas xaiv cov passive SFP + DAC high-speed cable thiab nquag cable
Lub passive SFP + DAC siab ceev cable tsis muaj hluav taws xob tiv thaiv thiab yog li yuav tsum tau siv hluav taws xob tsis txaus los ua haujlwm. Hloov chaw, nquag siv cov xaim hluav taws xob xav tau dc zog los sib sau ua ke ntawm cov teeb liab sib txuas rau hauv cov txuas sib txuas, uas ua rau lawv siv nyiaj ntau dua. Yog li no, thaum qhov kev nrug deb tsawg dua 7 meters, nws raug nquahu kom siv passive SFP + DAC txoj hlua hluav taws xob ntau; thaum qhov kev ncua deb tshaj 7 meters, kev siv cov xov tooj nquag yog qhov tsim nyog dua.
(2) tuaj yeem siv SFP + DAC tau tshaj high-speed cable ntawm Cisco hloov
Yog lawm, ib yam li cov kho qhov muag hluav taws xob tau yooj yim, tshaj SFP + DAC cov xov tooj hluav taws xob ntau yuav tau tsim rau tib txoj kev lag luam kev tsim ua cov cisco cov xov tooj hluav taws xob siab, thiab txhua tus tsim nyog siv SFP + DAC high-speed cable yuav raug sim nrog cov khoom siv cisco kom ntseeg tau tias lub network khiav ntseeg nkaws. Los ntawm yuav SFP + DAC txoj kev kub ceev cable los ntawm lub chaw tsim khoom txhim khu kev qha, koj tuaj yeem yuav cov khoom lag luam zoo thiab txuag tau nyiaj tib lub sijhawm.
(3) Cov SFP + DAC txoj kev kub ceev puas siv tau rau hauv SFP chaw nres nkoj?
SFP + DAC qhov siab ceev cable tuaj yeem thim rov qab-sib xyaw nrog SFP cov chaw nres nkoj kom paub tseeb tias txoj haujlwm ua haujlwm ntawm lub network. Txawm li cas los xij, SFP DAC txoj hlua hluav taws xob loj tsis sib haum nrog SFP + chaw nres nkoj. SFP DAC txoj kev kub ceev cable tuaj yeem txuas rau hauv SFP + chaw nres nkoj, tab sis tsis them rau 10G cov ntaub ntawv hloov tsheb.
Yuav ua li cas kuv thiaj li siv SFP + DAC high-speed cables hauv cov ntaub ntawv chaw?
SFP + DAC kev kub ceev cable yog kev sib txuas cable rau kom paub cov kev sib txuas lus high-speed kev sib txuas lus hauv kev ncua deb. Nws yog dav siv nyob rau hauv cov chaw zov me nyuam cov ntaub ntawv thiab chav tsev neeg rau khoom. Txhawm rau ua koj li SFP + DAC kev kub ceev cable ua haujlwm, ntawm no yog qhov yuav ua li cas siv SFP + DAC kev kub ceev cable hauv koj cov ntaub ntawv chaw.
(1) Suav qhov ntev ntawm SFP + DAC txoj kev kub ceev cable ua ntej
Thaum siv cov SFP + DAC kev kub ceev rau hauv qhov ntev txog 84-nti, 45RU txee, nws tau raug kwv yees hais tias qhov ntev cable los ntawm sab saum toj mus rau hauv qab ntawm lub txee yog kwv yees li 7 feet (2.1m) thiab qhov ntev ntawm cable ob Cov chaw nres nkoj uas nyob ib sab yog kwv yees li 1.5 feet (0.45m). Yog tias cov txee muaj ob qhov ToR hloov thiab 20 2U SFP + NIC cov neeg rau zaub mov, qhov yuav tsum muaj SFP + DAC qhov siab ceev cable yuav tsum yog 2.1 + 2 × 0.45≈3m. Txij ntawm no, koj tuaj yeem yuav 3m SFP + DAC txoj hlua hluav taws xob ntau.
(2) Tsis txhob tshaj qhov khoov lub vojvoog ntawm SFP + DAC high-speed cable
Thaum xa tawm ib qho SFP + DAC siab ceev cable, nco ntsoov tias lub cable tsis pub dhau qhov tsawg kawg nkaus khoov vojvoog txheem. Txhua SFP + DAC qhov siab ceev cable muaj qhov sib txawv tsawg txoj kev khoov vojvoog raws li USA hlau tag huv tibsi.
(3) Tiv thaiv koj li SFP + DAC qhov siab ceev cable nrog kev tswj cov cuab yeej
Txhawm rau tiv thaiv SFP + DAC kev kub ceev cov xaim hluav taws xob los ntawm kev sib tsoo vim muaj ntau dhau, nws tsim nyog siv cable tswj lossis cov cuab yeej kev ntxhov siab. Cov cuab yeej daws kev ntxhov siab tsis tuaj yeem tsuas yog xyuas kom pom txoj kev khoov lub vojvoog ntawm SFP + DAC high-speed cable raug tswj nyob rau hauv thaj chaw ib txwm, tab sis kuj tseem yooj yim rau txoj kab txoj kab cable kom ua kom zoo thiab muaj txheej txheem. Nyob rau tib lub sijhawm, cov cuab yeej kev tswj xyuas cable xws li siv lub pob zeb tuaj yeem siv los khi qhov hluav taws xob high-speed cable los txuas rau cov cuab yeej kev ntxhov siab, uas zoo rau kev ruaj ntseg rau lub cable.
