Ikhebula leDupsop liqukethe imicu emibili ezimele ye-fiber optic, ekwazi ukudlulisa amasiginali amabili ahlukene ahlukene ngasikhathi sinye, okwenza ukucubungula idatha efanayo kanye nokwenza ngcono ukuxhumana kahle. Uma kuqhathaniswa nezintambo ze-Simplex, amakhekhe ama-duplex angadlulisela idatha eminingi ngenani elifanayo lesikhathi, ahlangabezana nezidingo zokuxhumana eziphezulu. Kusetshenziswa izinto ze-fiber ezisezingeni eliphakeme, kuqinisekisa ukuthengiswa okuncane kwesiginali ngesikhathi sokudluliselwa, ukugcina ubuqotho bedatha nokuqina. Ikhebula le-Duplex linesakhiwo esihlangene, elinobubanzi obuncane obungaphandle kanye nesisindo esikhanyayo, okwenza kube lula ukufaka nocingo, ikakhulukazi ezindaweni ezikhawulelwe isikhala. Izixhumi ezinhlangothini zombili zekhebula zenzelwe ukufakwa okulula kokufakwa kwesayithi nokulungiswa, ukunciphisa izindleko zokusebenza.
Ngaphakathi kwezikhungo zedatha, izintambo ze-Duplex zisetshenziselwa ukuxhuma amaseva, amadivayisi wesitoreji, nokushintshwa kwenethiwekhi, ukusekela ukucubungula idatha okungcono kwedatha nesitoreji. Embonini yezokusakaza kanye nethelevishini, amakhebula ama-Duplex adlulisela amasignali amaningi wevidiyo achaza ngencazelo efanayo ngasikhathi sinye, okwenza ukuhanjiswa okuphezulu kwezinhlelo zokusakaza. Ekunakekelweni kwezempilo, amakhebula ama-duoplex angadlulisela amasiginali alalelwayo nevidiyo ngaphakathi kwekhebula elifanayo, axhase izinsizakalo ze-telemedicine, ukubonisana kwevidiyo, kanye nokucabanga kwencazelo ephezulu. Kuzinhlelo zezezimboni ezenzakalelayo, amakhebula ama-Dumplex adlulisa amasiginali amaningi enzwane ngasikhathi sinye, ethuthukisa ukunemba nokusebenza kahle kwezinto ezenzakalelayo zezimboni. Njengokhetho oluhle lwe-FTTH (i-fiber kuya ekhaya), amakhebula ama-duoplex) angaxhuma ngqo ku-ONU (i-Optical Network unit) amadivayisi emakhaya noma emahhovisi, ahlinzeka ngezinsizakalo zokufinyelela eziqinile, ezinzile zokufinyelela. Ezinhlelweni zokubhekwa kwezokuphepha, amakhebula ama-Dumplex adlulisela amasiginali amaningi okubhekwa kwevidiyo kanye nemininingwane ye-alamu ngasikhathi sinye, andise ukumboza kanye nejubane lokuphendula lohlelo lokubhekwa.
