Emkhakheni wezinhlelo zokuxhumana zesimanje, izamukeli ze-optical zidlala indima ebalulekile ekuqinisekiseni ukudluliswa kwedatha okuphumelelayo nokuthembekile. Lawa madivaysi anomthwalo wemfanelo wokuguqula amasignali abonakalayo abe amasignali kagesi, okuvumela ukudluliswa kolwazi ngaphandle komthungo kuwo wonke amanethiwekhi ahlukahlukene. Kule bhulogi, sizohlola ukubalulekaabamukeli be-opticalkanye nomthelela wazo ekuthuthukisweni kobuchwepheshe bezokuxhumana.
Abamukeli be-Optical yizici ezibalulekile ezinhlelweni zokuxhumana ze-optical, lapho idatha idluliselwa khona kusetshenziswa amasignali optical ngokusebenzisa imicu optical. Lezi zamukeli ziklanyelwe ukuthola amasignali okukhanya angenayo futhi ziguqule zibe izimpawu zikagesi, ezingase zicutshungulwe futhi zisetshenziswe izinto zikagesi. Le nqubo yokuguqula ibalulekile ukuze kuqinisekiswe ukuthi idatha edlulisiwe yamukelwa futhi ihunyushwa ngokunembile, okuvumela ukugeleza okungenazihibe kolwazi phakathi kwamanethiwekhi ahlukene okuxhumana.
Enye yezinzuzo eziyinhloko zabamukeli be-optical yikhono labo lokusingatha ukudluliswa kwedatha ngesivinini esikhulu. Njengoba isidingo samanethiwekhi okuxhumana asheshayo nasebenza kahle kakhudlwana siqhubeka sikhula, izamukeli ze-optical zidlala indima ebalulekile ekuhlangabezaneni nalezi zidingo. Ngokuguqula amasignali okukhanya abe amasignali kagesi, le mishini iyakwazi ukudlulisa idatha enkulu ngesivinini esikhulu ngendlela emangalisayo, okuyenza ibaluleke kakhulu ezinhlelweni zesimanje zokuxhumana.
Ukwengeza, izamukeli ze-optical zibalulekile ekugcineni ubuqotho besignali kanye nokunciphisa ukulahlekelwa kwesignali ngesikhathi sokudluliswa kwedatha. Ukuguqula amasignali okubonayo abe amasignali kagesi kukhulisa futhi kukhiqize kabusha idatha edlulisiwe, kuqinisekisa ukuthi ulwazi lufinyelela lapho luyiwa khona ngokuhlanekezela okuncane noma ukucekelwa phansi. Lokhu kubaluleke kakhulu ezinhlelweni zokuxhumana ezikude, lapho ukulahlekelwa kwesignali kungase kube nomthelela omkhulu ekusebenzeni okuphelele nokuthembeka kwenethiwekhi.
Ngaphezu kweqhaza lazo ekudluliselweni kwedatha, izamukeli ze-optical nazo zidlala indima ebalulekile ekuvumeleni ukuhlanganiswa kwezinhlelo zokuxhumana ezibonakalayo nezisetshenziswa zikagesi ezikhona namanethiwekhi. Ngokuguqula amasignali okubonayo abe amasignali kagesi, lezi zamukeli zisiza ukuhlanganiswa okungenazihibe kobuchwepheshe bokuxhumana obubonakalayo namasistimu kagesi endabuko, okuvumela ukushintshaniswa kwedatha okuphumelelayo kuzo zonke izinkundla ezihlukene.
Sekukonke,abamukeli be-opticalziyingxenye ebalulekile yezinhlelo zokuxhumana zesimanje futhi zidlala indima ebalulekile ekuvumeleni ukudluliswa kwedatha ngesivinini esiphezulu, ukugcina ubuqotho besignali, kanye nokwenza lula ukuhlanganiswa kobuchwepheshe bokuxhumana obubonakalayo namanethiwekhi akhona kagesi. Njengoba isidingo samanethiwekhi okuxhumana anokwethenjelwa akhula ngokushesha, ukubaluleka kwama-optical receiver ekuthuthukiseni intuthuko kubuchwepheshe bezokuxhumana angeke kugcizelelwe. Lawa madivayisi azoqhubeka nokudlala indima ebalulekile ekulolongeni ikusasa lezinhlelo zokuxhumana, okuvumela ukudluliswa kolwazi okungenazihibe kumanethiwekhi nezinkundla ezihlukahlukene.
