DAC cable yog dab tsi?
DAC yog lub xov tooj cua ceev, txuas txuas ncaj qha, lossis txuas ncaj qha txuas tooj liab cable. Hom kab no tsis tuaj yeem hloov chaw nres nkoj, thiab lub taub hau module thiab tooj liab tsis tuaj yeem sib cais.
Hauv cov chaw khaws ntaub ntawv, cov tooj liab tooj liab feem ntau yog siv los txuas cov servers thiab chaw khaws cia network. Qhov feem ntau siv yog Ncaj Ncaj Txuas Tooj Hluav Taws Xob (DAC, Txuas Txuas Tooj Tooj Tooj), thiab cov xov tooj tooj liab tsis zoo feem ntau siv. Txij li passive tooj liab cables yog pheej yig thiab nrawm, lawv tau dhau los ua qhov kev daws teeb meem zoo tshaj plaws rau kev xa mus luv-nrug.
DACs feem ntau yog siv ntawm cov hloov pauv hauv cov chaw siv computer. DACs tuaj yeem ua haujlwm lossis tsis ua haujlwm, thaum AOCs txhua tus nquag.
Qhov zoo ntawm kev kub ceev cable DAC suav nrog kev ua haujlwm siab, txuag lub zog thiab kev tiv thaiv ib puag ncig, kev siv hluav taws xob tsawg, thiab tus nqi qis. Nws yog qhov tsim nyog rau cov xov hluav taws xob luv-nrug nyob hauv cov chaw khaws ntaub ntawv, nrog rau ntau yam kev siv thiab muaj peev xwm ua ke muaj zog. Cov khoom siv sab hauv ntawm cov kab hluav taws xob nrawm yog tooj liab tooj liab, thiab cov tooj liab tooj liab muaj cov cua sov ua kom sov zoo, txuag hluav taws xob thiab tiv thaiv ib puag ncig. Cov kab hluav taws xob muaj qhov siv hluav taws xob tsawg. Txij li cov kab hluav taws xob tsis xav tau lub zog, lub zog siv yuav luag xoom; kev siv hluav taws xob ntawm cov kab hluav taws xob feem ntau nyob ib puag ncig 440mW. Tus nqi ntawm tooj liab cable yog qis dua li ntawm fiber ntau qhov muag. Yog li ntawd, kev siv cov kab hluav taws xob ceev tuaj yeem txo tus nqi cabling ntawm tag nrho cov ntaub ntawv chaw.
