Nthawi zambiri, chingwe chogwira ntchito (AOC) ndi chingwe cholumikizira mwachindunji (DAC) chimakhala ndi izi:

① Kugwiritsa ntchito mphamvu mosiyanasiyana: kugwiritsa ntchito mphamvu kwa AOC ndikokwera kuposa kwa DAC;

②Matali osiyanasiyana opatsirana: Mwachidziwitso, mtunda wautali kwambiri wa AOC ukhoza kufika 100M, ndipo mtunda wautali kwambiri wa DAC ndi 7M;

③Sing'anga yopatsira ndi yosiyana: njira yotumizira ya AOC ndi fiber optical, ndipo njira yotumizira ya DAC ndi chingwe chamkuwa;

④Zizindikiro zotumizira ndizosiyana: AOC imatumiza ma siginecha owoneka bwino, ndipo DAC imatumiza ma siginecha amagetsi;

⑤ Mitengo yosiyana: mtengo wa optical fiber ndi wapamwamba kuposa wamkuwa, ndipo mbali ziwiri za AOC zili ndi lasers koma osati DAC, kotero mtengo wa AOC ndi wapamwamba kwambiri kuposa wa DAC;

⑥Voliyumu yosiyana ndi kulemera kwake: Pansi pa utali womwewo, voliyumu ndi kulemera kwa AOC ndizocheperako kuposa za DAC, zomwe ndizosavuta kuyimba ndi kuyendetsa.

Choncho tikamasankha zingwe, tiyenera kuganizira zinthu monga mtunda wotumizira komanso mtengo wa waya.Nthawi zambiri, DAC itha kugwiritsidwa ntchito mtunda wolumikizana mkati mwa 5m, ndipo AOC itha kugwiritsidwa ntchito polumikizana mtunda wa 5m-100m.
