Nyob rau niaj hnub no qhov kev hloov pauv sai sai ntawm cov duab digital, cov chaw zov me nyuam cov ntaub ntawv ua lub luag haujlwm tseem ceeb hauv kev khaws cia, tswj, thiab xa cov ntaub ntawv ntau heev. Tom qab lub scenes ntawm cov thev naus laus zis powerhouses yog ib tug complex infrastructure uas enables seamless cov ntaub ntawv ntws. Ib qho tseem ceeb ntawm cov ntaub ntawv chaw zov me nyuam yog cabling, uas tsim cov caj qaum ntawm kev sib txuas. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv lub ntiaj teb no ntawm cov ntaub ntawv chaw cabling, tshawb txog ntau hom cabling thiab cov qauv uas tswj lawv cov kev siv.
Hom ntawm Data Center Cable
Copper Cable:
Copper cabling, xws li twisted khub cables, tau ntev tau ib qho kev xaiv nrov rau cov chaw zov me nyuam. Nws muaj kev txhim khu kev qha kev ua tau zoo rau luv mus rau nruab nrab nrug thiab yog tus nqi-zoo. Cov qauv siv tooj liab feem ntau siv hauv cov chaw khaws ntaub ntawv yog Qeb 6A (Cat 6A), uas txhawb nqa kev sib txuas siab Ethernet mus txog 10 Gigabits ib ob (Gbps) thiab rov qab sib xws nrog cov qeb qis.
Fiber Optic Cable:
Fiber optic cabling tau dhau los ua ntau dua nyob rau hauv cov chaw zov me nyuam vim nws cov ntaub ntawv sib txuas tsis sib xws thiab kev tiv thaiv kev cuam tshuam rau electromagnetic cuam tshuam. Muaj ob hom fiber ntau optic cables siv nyob rau hauv cov ntaub ntawv chaw: ib hom fiber ntau (SMF) thiab ntau hom fiber ntau (MMF). SMF yog qhov zoo tagnrho rau kev sib kis mus ntev, thaum MMF yog qhov tsim nyog rau kev ncua deb ntawm cov ntaub ntawv chaw. Feem ntau siv fiber ntau optic cabling cov qauv suav nrog OM3, OM4, thiab OS2, txhua qhov muab cov bandwidth sib txawv thiab ncav cuag lub peev xwm.
Data Center Cabling Standards
TIA-942:
Lub Koom Haum Kev Lag Luam Kev Lag Luam Sib Txuas (TIA) tau tsim TIA-942 tus qauv, uas muab cov lus qhia rau kev tsim thiab siv cov ntaub ntawv chaw tsim khoom. Nws suav nrog ntau yam, suav nrog cov cabling, topology, redundancy, thiab kev ruaj ntseg ntawm lub cev. TIA-942 xyuas kom meej tias cov chaw zov me nyuam ua tau raws li qee qhov kev ua tau zoo, kev ntseeg tau, thiab cov txheej txheem scalability.
ANSI/TIA-568:
ANSI/TIA-568 tus qauv yog dav lees paub tias yog lub hauv paus rau cov kab ke sib txuas. Nws qhia txog qhov yuav tsum tau muaj rau cov kab sib txawv, cov khoom sib txuas, thiab kev sib kis tau zoo. Qhov tseeb iteration, ANSI/TIA-568-C.3, tsom tshwj xeeb rau fiber optic cabling systems.
ISO/IEC 11801:
ISO / IEC 11801 tus qauv muab cov txheej txheem thoob ntiaj teb rau cov kab ke sib txuas, suav nrog cov siv hauv cov chaw khaws ntaub ntawv. Nws npog ob qho tib si tooj liab thiab fiber ntau optic cabling, hais txog yam xws li kev ua tau zoo, kev teeb tsa, kev sim, thiab kev saib xyuas. Ua raws li tus qauv no ua kom muaj kev sib raug zoo thiab kev sib raug zoo nrog kev sib txuas lus thoob ntiaj teb.
Xaus
Data center cabling yog ib qho tseem ceeb ntawm cov kev tsim kho vaj tse uas ua rau cov ntaub ntawv sib txuas thiab sib txuas. Los ntawm kev nkag siab txog ntau hom kev sib txuas, xws li tooj liab thiab fiber ntau optic, thiab cov qauv sib txuas xws li TIA-942, ANSI/TIA-568, thiab ISO/IEC 11801, cov kws tshaj lij cov ntaub ntawv tuaj yeem tsim, siv, thiab tswj kev txhim khu kev qha thiab kev ua haujlwm siab cabling tshuab. Ua kom nrawm nrog kev nce qib hauv kev siv tshuab cabling thiab ua raws li cov qauv kev lag luam yog qhov tseem ceeb rau kev ua kom muaj txiaj ntsig zoo thiab npaj ua haujlwm rau yav tom ntej.
