1. Txiav txim xyuas saib qhov twg muaj kev sib txig ntawm khub
Cov xov hlau nyob hauv txoj kab sib ntswg-khub cable tshwm nyob rau hauv khub, txhua tus ntawm cov khub, thiab lawv tau sib puag ncig nyias. Raws li Asmeskas Kev Tshaj Lij thiab Kab Npab Kev Qhia Tau Zoo (AWG), cov xaim xaim nyob hauv tus khub sib tw yuav tsum yog 4 khub, tag nrho yog 8 xaim. Txawm li cas los xij, 10M Ethernet tus qauv qhia tias tsuas yog 2 khub ntawm xaim siv los xa cov cim, yog li qee qhov ntawm 3 hom kev sib tw muaj 2 khub, thiab qee qhov yog 4 khub.
Kev tshwm sim ntawm Fast Ethernet, ntawm ib sab, raws li kev ua kom tau qhov kev nrawm ntawm lub qub 10M network los ntawm 10 zaug, thiab ntawm qhov tod tes, nws tab tom npaj rau lub network nrawm dua yav tom ntej (Gigabit Ethernet, kis tau tus mob ceev yog 1000Mbps), thaum kis Qhov 5 yam nkhaus khub txuas txuas nrog nrawm ntawm 100Mbps kuj tseem muab tso rau siv. Txawm hais tias Fast Ethernet tsuas yog siv 2 khub xwb, Gigabit Ethernet yuav tsum siv tag nrho 4 khub.
Nws raug pom zoo tias koj saib cov ntawv sau ntawm lub network cable. Yog tias nws tau cim nrog" CAT3", feem ntau nws yog qeb 3 cable, thiab thaum nws raug cim nrog" CAT5" ;, nws yog qeb 5 twisted khub cable.
2. Qhov tseeb ntsuas nws nrawm
Cov tes hauj lwm uas tam sim no tsim kho feem ntau siv cov qeb 5 lossis ntau tus xov tooj sib txuas ua ke, thiab cov qeb 3 sib txuas cov xov tooj hluav taws xob twb dhau los lawm cov khoom lag luam. Txawm li cas los xij, tom qab kev qhia ntawm qeb 5 twisted khub txheem, qee cov twisted khub manufacturers ntim cov xov hlau xaim siv thawj rau Pawg 3 xov hlau hauv cov ntawv luam tawm nrog Pawg 5 twisted khub rau muag. Thaum koj siv hom Qib fake 5 cable, qhov tseeb kev sib txuas lus ntawm lub network tsuas tuaj yeem ncav cuag 100Mbps tau teev tseg los ntawm qeb 5 sib tw khub tsis pub dhau ib ntus luv.
Qhov kev dag ntxias no yog zais heev, thiab nws yog qhov nyuaj rau cov neeg siv dog dig nrhiav nws. Lub sijhawm no, nws raug nquahu kom koj yuav ib ntu ua ntej thiab siv" Kev Teeb Meem Saib Xyuas" hauv Windows98 lossis" Network Monitor" hauv WindowsNTServer4.0 los sim nws koj tus kheej. Yog tias qhov kev xeem ceev ncav cuag 100Mbps, nws qhia tau tias nws yog Pawg 5 twisted khub.
Yog tias tsuas yog 10Mbps, nws txhais tau hais tias lub cable siv cov xov tooj ntawm qeb 3 xaim. Txoj kev no tsis tuaj yeem tsuas yog paub qhov txawv ntawm qeb 3 xaim thiab qeb 5 xaim, tab sis kuj tuaj yeem siv los ntsuas seb qhov sib txawv ntawm txhua qib ntawm cov xov hlau nyob rau hauv kev sib txuas ntawm cable puas tau raws li tus qauv, thiab nws tseem tuaj yeem kuaj seb cov hlau nruab nrab hauv cov hlau yog tsim nyog. Thov nco tseg: Thaum kuaj lub network ceev, qhov ntev ntawm cov twisted khub cable yuav tsum tus qauv ntev 100 meters, txwv tsis pub ntsuas cov ntaub ntawv tsis muaj qhov tseem ceeb tseem ceeb.
3. Ntseeg koj tus kheej lub qhov muag
Tsis yog txhua lub xov hluav taws xob muaj nyob rau hauv chav ua haujlwm huab cua, yog li lub network cable yuav tsum muaj qee qhov ntawm qhov kub tsis kam, lub zog ntawm lub zog thiab qhov yooj: thawj, koj tuaj yeem sim cov sib ntswg hauv qhov kub ntawm ib puag ncig. Tiag tiag Thaum qhov ntsuas kub nyab xeeb ntawm cov khub sib txig mus txog 35 ° C txog 40 ° C, txheej roj hmab txheej sab nraud yuav tsis ua mos muag, thaum tus cuav yuav.
Txhawm rau kom muaj kev nyab xeeb ntawm kev sib txuas, cov roj hmab khi ntawm cov sib txuas tiag-khub cable muaj muaj zog tensile tsis kam, thaum lub cuav ib qho tsis; tooj liab tooj liab feem ntau yog siv hauv cov xov paj sib ntswg, thiab qee cov tuam ntxhab Muaj Lwm cov khoom siv hlau txuas ntxiv rau tooj liab. Qhov ua tau zoo yog tias cov hlau xaim yog qhov nyuaj tshaj qhov qub, tsis yooj yim khoov, thiab nws yooj yim kom tawg thaum siv.
Cov roj hmab ntoo nyob sab nraud ntawm qhov sib txawv tiag tiag khub kuj yog nplaim hluav taws tiv thaiv, thaum tus cuav ib qho yog ua los ntawm cov khoom ua kom zoo nkauj. Koj tuaj yeem sim koj tus kheej thaum koj yuav; thaum koj yuav tsum tau siv daim thaiv npog uas muaj thaiv me ntsis, koj yuav tsum them sai sai rau daim thaiv npog cov xov paj khub. Nws yog qhov txawv heev ntawm qhov tsis muaj peev xwm ruaj khov kho khub uas peb nquag siv. Piv nrog rau cov khub tsis sib txig sib xyaw, muaj txheej txheej ntxiv ntawm cov hlau tsis xeb thiab txheej nyias txheej ntawm cov ntaub thaiv qhov nruab nrab ntawm cov xov hlau ntawm cov ntaub thaiv npog sib ntswg thiab cov roj hmab sab nraud, thiab sab nraud ntawm cov siv lead ua lub taub hau yog qhwv nrog hlau.
Cov no yog peb ib feem ntawm kev ua lag luam hauv Alibaba, yog tias koj xav yuav, pls so ruaj khov, vim tias nws' s muaj kev nyab xeeb thiab muab kev lees paub rau peb ib leeg.
