AOC yog nquag kho qhov muag cable, uas yog tsim ntawm optoelectronic li (ob lub tshuab xa hluav taws xob thiab cov kho qhov muag cable). Lub tshuab hluav taws xob tsis zoo siv dav siv hauv cov chaw zov me nyuam, cov khoos phis tawm siab, kev ntim khoom loj thiab lwm yam khoom siv los nqa cov khoom nrawm thiab txhim khu kev qha kev sib kis. Daim ntawv thov AOC yog qhov sib txuas hluav taws xob uas ua tau raws li qhov xav tau ntawm cov qauv kev lag luam. Nws siv sab hauv hluav taws xob-kho qhov muag-hloov hluav taws xob ntawm lub kho qhov muag los ua kom lub cable kho qhov muag kom ua tau cov ntaub ntawv xa tau zoo thiab ruaj khov.
DAC yog qhov txuas kev kub ceev ncaj qha rau cable, uas tseem tuaj yeem raug hu ua cov txuas txuas tooj liab tooj liab. Lub chaw nres nkoj cable no tsis tuaj yeem hloov tau, thiab lub taub hau thiab txoj kab txuas tooj liab tsis tuaj yeem sib cais. Tooj liab tooj liab yog cov xov tooj uas tau txuas ncaj qha rau kab txuas rau cov chaw txuas thiab cov chaw khaws cov khoom hauv thaj chaw. Kev txuas ncaj qha tooj liab tooj liab tau raug faib ua cov txuas tooj liab tooj liab thiab nquag tooj liab tooj liab. Ntawm lawv, passive tooj liab tooj liab tau siv ntau zaus. Vim tias cov xaim tooj liab hluav taws xob muaj nqi zoo thiab nrawm, lawv muab cov kev daws teeb meem zoo tshaj plaws rau kev sib kis tau luv. Kev Pabcuam. DAC cov kab hluav taws xob feem ntau yog siv ntawm cov ntsuas hluav taws xob hauv cov ntaub ntawv chaw nruab nrab hauv chav computer, thiab ob leeg siv zog ua haujlwm thiab siv tau.
