DAC (Direct Txuas Txuas Cable) zoo li AOC zoo li. Nws kuj tseem yog xaim nrog ob ntu hlua khi ntawm txhua qhov kawg, tab sis cov hlau nruab nrab yog tooj liab Cable es tsis siv cov fiber ntau.
AOC hu ua cable nquag, thaum DAC tau muab faib ua nquag thiab nquag, thiab cov ntsiab hluav taws xob ua haujlwm tsis muaj zog. Qee cov chaw tsim khoom hauv xov xwm kom cia DAC tuaj yeem kis tau mus deb, uas ntxiv cov teeb liab ua kom nrov nrov, qhov no yog qhov nquag tooj liab cable.
Hais lus nruj me ntsis, DAC tsis yog qeb ntawm cov qauv kho qhov muag; nws tsuas yog saib zoo li optical module ntawm sab nraud, tab sis sab hauv, nws tsis muaj dab tsi los ua nrog cov khoos phis tawj qhov kho qhov muag. Tsis muaj cov lasers, tsis muaj suab txuas ntxiv, tsis pom, thiab tsis muaj tus MCU tswj hwm zoo ib yam li cov hloov kho qhov muag. Hauv lwm lo lus, tus nqi tseem ceeb tshaj plaws nyob rau hauv cov kho qhov muag / AOC, DAC, tsis muaj cov tswj yooj yim nti rau cov teeb liab hluav taws xob, uas yog kis tau los ntawm qhov pib thaum kawg. Qhov no yog vim li cas tus nqi ntawm DAC yog tus nqi qis dua qhov ntsuas hluav taws xob thiab AOC.
Peb paub tias thaum lub khoos phis tawm ntawm optical lossis AOC txhaws rau hauv lub pob hluav taws xob hloov, qhov ntsuas hluav taws xob, qhov tam sim no, qhov kub thiab txias, txais thiab xa cov khoom siv fais fab ntawm lub khoos phis tawj ntawm qhov sib txuas tau pom tau los ntawm kev siv cov lus txib ntawm lub pob hloov. Tab sis yog tias plugging DAC tsis' t feem ntau nyeem cov ntaub ntawv no, vim li cas thiaj yog? Qhov laj thawj yog tias ob qho khoos phis tawm kho qhov muag thiab AOC muaj cov khw muag khoom DDM uas khaws cov ntaub ntawv no. Hauv DAC, ntawm ib sab, tsis muaj lub tswv yim ntawm kev tau txais thiab kis tau lub zog kho qhov muag; ntawm qhov tod tes, tsis muaj MCU nti nrog lub zog ua kom muaj zog txhawm rau txhawm rau ntsuas kub, voltage thiab tam sim no. Yog li, DAC feem ntau tsis muaj cov ntaub ntawv DDM. Thaum koj pom tias DAC tuaj yeem' t nyeem cov ntaub ntawv no, tsis txhob ntseeg' tsis ntseeg qhov hloov, tsis txhob ntseeg' t ntseeg DAC, qhov no yog ib qho kev coj ua hauv kev lag luam.
Vim tias DAC yog lub zog tsav hluav taws xob, yog li qhov kev ncua deb feem ntau tsis nyob deb, vim tias lub teeb liab hluav taws xob tshaj lub teeb liab hluav taws xob feem ntau yuav raug txwv los ntawm qhov kev ncua deb (tsis zoo los cuam tshuam lub peev xwm), feem ntau tsis pub dhau 5M, tshwj tsis yog cov nquag siv cable, ntxiv rau lub suab nrov. Piv nrog rau lub teeb, hluav taws xob teeb tau ntau dua los cuam tshuam los ntawm qhov deb, ntsuas kub, hluav taws xob, cable folding thiab lwm yam teeb meem, yog li DAC muaj qhov cuam tshuam ntau tshaj qhov teeb meem tau tshaj AOC, nyob ntawm kev tsav lub peev xwm ntawm cov khoom siv ntawm ob xaus. Rau AOC, cov teeb meem tseem ceeb yog tias fiber ntau tawg tau yooj yim, thiab tau kawg, hnub no pom ntau lub teeb pom kev zoo nkauj tau yooj yim.
Yog li feem ntau, yog hais tias ib puag ncig yog tswj tau, qhov deb tsis ntev, tus nqi yog rhiab, thiab cov teeb meem sib xyaw yuav raug tshem tawm ua ntej, DAC yog kev xaiv zoo.
