Ake ucabange ngezwe lapho ukugcinwa kwedatha kuyinkumbulo ekude, i-lag ingaziwa, futhiumhlaba wedijithaliishesha ngendlela olindele ukuthi ibe ngayo. Konke lokhu kungenzeka ngenxai-fiber yangaphakathiizintambo. Imicu yengilazi ezacile idlulisa idatha isebenzisa ama-pulses alula, idala ukukhuphuka okukhulu ekusebenzeni nokuthembeka kwakhoikhaya elihlakaniphilephezu kwezintambo zethusi. Ake singene kancane kuleyo khebula efihlekile, ye-fiber optics yasendlini futhi sithole ukuthi yini ekwenza kuphawuleke ekuguquleni ukuphila kwakho okuxhunyiwe.
