ONU (Optical Network Unit) bụ ngwa nnyefe ngwa anya ejiri na sistemụ nkwurịta okwu fiber optic nwere ọrụ abụọ nke “zipu” na “nata”.Ọ bụ ngwaọrụ dị na netwọk anya na-ejikọ eriri anya na akụrụngwa onye ọrụ.Nkwukọrịta fiber optic bụ teknụzụ nkwukọrịta nke na-eji ọkụ dị ka mgbama Bellman, ONU bụ otu n'ime akụrụngwa kachasị mkpa maka nzikọrịta ozi na nnyefe.Tụnyere akụrụngwa netwọkụ ọkọlọtọ, ONU nwere njirimara abụọ:
Nke mbụ, n'ihe gbasara njikọta anụ ahụ, ONU na-eji eriri fiber optic kama iji eriri netwọk ọdịnala.N'ihi na eriri fiber optic nwere nnukwu nnyefe ọsọ, ikike nnyefe data dị elu, yana anya nnyefe dị ogologo, ọ dabara nke ọma maka nnyefe data dị elu na ọsọ ọsọ.
Nke abụọ, ONU na-eji teknụzụ pụrụ iche nke TDMA (Time Division Multiple Access) na-ebufe data na ndị ọrụ dị iche iche n'oge dị iche iche iji hụ na nkwụsi ike na nchekwa nke nnyefe data.
