Whakataki: Ko te ONU (Optical Whatunga Waehanga) kua wehea ki te waeine whatunga whatu hohe me te waeine whatu whatu hāngū, Ko ONU te pūrere kāpeka kaiwhakamahi i roto i te whatunga whatu, whakanohoia ki runga ki te mutunga kaiwhakamahi, whakamahia ki te OLT ki te whakatutuki i Ethernet Apa 2, Apa 3 mahi , ki te whakarato i nga kaiwhakamahi ki te reo, raraunga me nga ratonga rongorau.
Whakaahuatanga tohu Paewhiri ONU:
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
LOS Maama: Weto: Pūnoa
Kaiwhakawa hapa kaiwhakamahi:
Ko te nuinga o nga hapa ko nga hapa o te raina muka whatu me nga hapa taputapu ONU.Tuatahi, tirohia mehemea he mea noa te tohu paewhiri.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 o ONU ka pa te urunga Ipurangi a 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 e tika ana te mana o te muka o te muka, tena koa whakakapihia te hiku poaka e manawapa ana, me te whakamahi i te mita hiko whatu hei whakamatautau i tetahi tohu hei hono atu ki te hiku o te whare.
2.Ki te he te raina muka whatu: tuatahi wetekina te hiku o te poaka i runga i te ONU ki te whakamatautau i te mana whatu, ki te kahore he marama, he kore mana ranei te mana, tēnā haere ki te flange o te pouaka whakawhiti taura whatu ki te kitea te tetahi o nga poaka 1-32 o te wehenga whatu e rite ana ki te ONU Mena kaore i te tika te poaka, ka taea e koe te whakakapi tetahi o nga poaka poaka 1-32 mangere.Kia maumahara: kaore e taea te kumea te muka matua o te wehenga whatu, ka pa ki te ONU katoa.
Whakaahuatanga tohu Paewhiri ONU:
Te rama hiko: Ka ka tonu te rama kaakaariki: Ka kaha te hiko;Ka mutu te rama kaakaariki: Whakawetohia te hiko
LOS Maama: OFF: Ko te mana whatu riro o te tauranga PON he noa;Ka mau tonu te rama kaariki: Kua kitea te taputapu, kua rehitatia;Kimo te rama matomato: Karekau he raraunga o te taputapu;Kimo: Ko te tauranga PON karekau he marama, he iti ake ranei te mana whatu i te maaramatanga whiwhi.
Ko LAN1, LAN2, LAN3 me LAN4 he Tauranga 4RJ45 katoa
Ko FXS1 he Tauranga Reo
Raparongoā: Tuatahi, tirohia mehemea kei te rere noa te taputapu ONU (mehemea he maamaa te rama tohu o 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.
