I-Optical fiber transceiveriyidivayisi engabizi kakhulu futhi evumelana nezimo. Ukusetshenziswa okuvamile ukuguqula amasignali kagesi ngamapheya asontekile abe amasignali okubona. Ngokuvamile isetshenziswa kuzintambo zethusi ze-Ethernet ezingakwazi ukumbozwa futhi kufanele zisebenzise imicu yokubona ukuze kunwetshwe ibanga lokudlulisela. Endaweni yenethiwekhi yangempela, iphinde idlale indima enkulu ekusizeni ukuxhuma imayela lokugcina lemigqa ye-fiber optic kunethiwekhi yendawo yedolobha elikhulu kanye nenethiwekhi yangaphandle. Iswishi iyidivayisi yenethiwekhi esetshenziselwa ukudlulisela isignali kagesi (i-optical), futhi idlala indima ebalulekile ekuxhumaneni phakathi kwamadivayisi enethiwekhi anentambo (njengamakhompyutha, amaphrinta, amakhompyutha, njll.)
