Kupu Whakataki:ONU(Waehanga Whatunga Optical) kua wehea ki te waeine whatunga whatu hohe me te wae whatunga whatu hāngū,ONUKo te taputapu tauranga kaiwhakamahi i roto i te whatunga whatu, ka whakanohoia ki te pito o te kaiwhakamahi, whakamahia meOLTki te whakatutuki i nga mahi a Ethernet Layer 2, Layer 3, ki te whakarato i nga kaiwhakamahi ki te reo, raraunga me nga ratonga rongorau.
ONUWhakaahuatanga tohu Paewhiri:
Maama hiko: Kakariki Weto: He kore te hiko; Kakariki Ka: Whakawerahia te hiko
Maama PON: Kakariki ki runga: roa ki runga e tohu ana kua paahitia e te poari te whakamatautau-whaiaro me te mahi noa o nga taputapu

Kaiwhakawa hapa kaiwhakamahi:
Ko te nuinga o nga hapa ko nga hapa raina muka whatu meONUnga hapa o nga taputapu. Tuatahi, tirohia mehemea he mea noa te tohu o te panui. I te korenga o te raina muka whatu, tirohia te mana o te rama PON: mena he kaakaariki te rama PON, ka tohu he mea noa te raina muka whatu, a mena ka mutu te rama PON, ka tohu kua momotuhia te raina muka whatu.
Whakamatautauria te raina muka whatu me te mita hiko whatu. Ko te awhe tohu o te mana whatu ko: 1490nm awhe: – 8dB ki – 28dB. Mena ka nui ake i te awhe, ka pa ki te kounga mahi noa oONUa ka pa te urunga Ipurangi o te kaiwhakamahi. Tirohia te raina muka whatu taumata o runga, ka whakamatau i te muka hiku o te wehenga e rite ana ki te taura whatu a te kaiwhakamahi he i te pouaka taura whatu.
Ko te attenuation o te wehenga whatu 2-ara ko -3db
Ko te attenuation o te wehenga whatu 4-ara ko -6db
Ko te attenuation o te wehenga whatu 8-ara ko -9db
Ko te attenuation o te wehenga whatu 16-ara ko -12db
Ko te attenuation o te wehenga whatu 32-ara ko -15db
Ko te attenuation o te wehenga whatu 64-ara ko -18db
1.Mehemea he tohu te mana o te whakaputanga o te poaka poaka wehewehe, tena koa whakakapihia te matua muka i waenga i te pouaka whakawhiti taura me te whare. Ko te tikanga, e rua nga waahanga muka e takoto ana i roto i te whare, ka whakamatau i te mutunga i muri i te whakakapinga. Mena ko te hiku mai i te wehenga me te kore o te mana o te muka o te muka, tena koa whakakapihia te hiku poaka e manawapa ana, me te whakamahi i te mita hiko hei whakamatautau i tetahi tohu hei hono atu ki te hiku o te whare.
2.Ki te he te raina muka whatu: tuatahi unu te hiku poaka i runga i teONUki te whakamatautau i te mana whatu, mena karekau he marama, kaore ranei te mana e whai mana, haere koa ki te flange o te pouaka whakawhiti taura whatu ki te kimi i tetahi o nga poaka 1-32 o te wehenga whatu e rite ana ki teONUMena karekau te hiku o te poaka, ka taea e koe te whakakapi i tetahi o nga hiku poaka 1-32 mangere. Kia maumahara: e kore e taea te kumea te muka matua o te wehenga whatu, ka pa ki te katoaONU.
ONUWhakaahuatanga tohu Paewhiri:
Maama hiko: Ka ka tonu te rama kaakaariki: Ka kaha te hiko; Ka mutu te rama kaakaariki: Whakawetohia te hiko

Raparongoā: Tuatahi, tirohia mehemea kei teONUKei te rere noa te taputapu (mehemea he maamaa te rama tohu i te paewhiri taputapu), ka tirohia etahi atu take i muri i te rere o te taputapu. He rite tonu te tukanga ki nga korero o runga ake nei.
