Ngokuvamile, ikhebula elibonakalayo elisebenzayo (AOC) kanye nentambo yokunamathisela eqondile (DAC) inomehluko olandelayo:

① Ukusetshenziswa kwamandla okuhlukile: ukusetshenziswa kwamandla kwe-AOC kungaphezulu kwalokho kwe-DAC;

②Amabanga ahlukene okudlulisela: Ngokombono, ibanga elide lokudlulisela le-AOC lingafinyelela ku-100M, kanti ibanga elide kakhulu lokudlulisela le-DAC ngu-7M;

③I-transmission medium ihlukile: i-transmission medium ye-AOC iyi-optical fiber, kanti i-DAC yokudlulisela ikhebula lethusi;

④Amasiginali wokudlulisa ahlukile: I-AOC idlulisa amasignali okubona, futhi i-DAC idlulisa amasignali kagesi;

⑤Izintengo ezihlukile: intengo ye-optical fibre iphezulu kunaleyo yethusi, futhi amaphethelo amabili e-AOC aqukethe amalaser kodwa hhayi i-DAC, ngakho intengo ye-AOC iphezulu kakhulu kunaleyo ye-DAC;

⑥Ivolumu ehlukile nesisindo: Ngaphansi kobude obufanayo, ivolumu nesisindo se-AOC kuncane kakhulu kunele-DAC, elungele izintambo nokuthuthwa.

Ngakho uma sikhetha izintambo, kudingeka sicabangele izici ezifana nebanga lokudlulisela kanye nezindleko zokufaka izintambo.Ngokuvamile, i-DAC ingasetshenziselwa amabanga okuxhumana phakathi kwama-5m, futhi i-AOC ingasetshenziselwa amabanga okuxhumana ebangeni lika-5m-100m.
