I-Optical fiber transceiversisixhobo esingabizi kakhulu kwaye sibhetyebhetye. Ukusetyenziswa okuqhelekileyo kukuguqula imiqondiso yombane kwizibini ezijijekileyo zibe yimiqondiso ye-optical. Ngokuqhelekileyo isetyenziswa kwiintambo zobhedu ze-Ethernet ezingenako ukugqunywa kwaye kufuneka zisebenzise iifiber zamehlo ukwandisa umgama wothumelo. Kweyona ndawo yothungelwano, ikwadlala indima enkulu ekuncedeni ukudibanisa imayile yokugqibela yemigca yefiber optic kuthungelwano lwendawo yemetropolitan kunye nothungelwano lwangaphandle. Iswitshi sisixhobo sothungelwano esisetyenziselwa ukuhanjiswa kombane (i-optical), kwaye idlala indima esembindini kunxibelelwano oluphakathi kwezixhobo zothungelwano ezinocingo (ezifana neekhompyutha, iiprinta, iikhompyutha, njl.njl.)
