Kupu Whakataki:ONU(Waehanga Whatunga Optical) kua wehea ki nga waeine whatunga whatu hohe me nga waeine whatunga whatu hāngū.ONUhe taputapu kaiwhakamahi i roto i nga whatunga whatu, ka whakanohoia ki te pito o te kaiwhakamahi, ka whakamahia tahi meOLTki te whakatutuki i nga mahi a Ethernet Layer 2 me te Layer 3, te whakarato i nga kaiwhakamahi ki te reo, raraunga, me nga ratonga rongorau.
Whakaahuatanga oONUtohu paewhiri:
KORE rama: kakariki weto: hiko whakaweto: hiko hiko
Maama PON: Kakariki ki runga: Ko te roa ki runga e tohu ana kua paahitia e te poari te whakamatautau whaiaro me te rere o te taputapu
rama LOS: karekau i te: ahua noa
Whakatauhia nga hapa kaiwhakamahi:
Ko nga hapa ko te nuinga o nga hapa ara whatu meONUnga hapa o te taputapu. Tuatahi, tirohia mena he maamaa te rama tohu o te panui. Tirohia te mana rama PON mo nga hapa o te ara whatu: ko te rama PON te tikanga ka tahuna ki te matomato, e tohu ana he mea noa te ara whatu, ka mutu te rama PON, e tohu ana kua pakaru te ara whatu.
Whakamahia he mita hiko whatu hei whakamatautau i te ara whatu. Ko te awhe e whakaaetia ana o te mana whatu ko: 1490nm: – 8db ki – 28db. Mena ka nui ake te awhe, ka pa ki te kounga mahi noa o teONU, a ka pa te uru ipurangi o te kaiwhakamahi. Tirohia te ara whatu taumata o runga, ka haere ki te pouaka tuku taura whatu ki te whakamatautau i te muka hiku o te wehenga e rite ana ki te taura whatu a te kaiwhakamahi he.
Atenuation o 1:2 hongere wehenga he – 3 db
Ko te 1:4 te whakahiatotanga o te hongere he – 6db
Ko te whakahekenga o te wehenga hongere 1:8 he – 9db,
1:16 hongere whakahiato attenuation ko - 12db,
Ko te attenuation o te 1:32 hongere wehewehe he – 15 db,
Ko te attenuation o 1:64 hongere wehenga he – 18db,
1、 Mena he tohu te mana o te whakaputanga o te poaka poaka, whakakapia te matua muka i waenga i te pouaka honohono taura whatu me te whare. I te nuinga o te waa, e rua nga waahanga muka ka whakatakotoria ki te whare, katahi ka whakahaere i nga whakamatautau mutunga i muri i te whakakapinga. Mena kaore i tika te mana o te hiku o te poaka mai i te wehenga, whakakapihia te toenga poaka, me te whakamahi i te mita hiko whatu hei whakamatautau i tetahi tohu hei hono atu ki te hiku o te whare.
Mēnā he hē te ara whatu: Tuatahi, wetewetehia te hiku poaka i runga i teONUhei whakamatautau i te mana whatu. Mena karekau he marama, kaore ranei te mana e whai mana, tirohia koa tetahi o nga poaka 1-32 e rite ana ki teONUi runga i te flange o te pouaka honohono taura whatu, ka wetekina te hiku poaka mai i te flange hei whakamatautau i te mana whatu. Mena karekau te hiku o te poaka, whakakapihia tetahi o nga hiku poaka 1-32 mangere. Kia maumahara e kore e taea te wetewete i te muka matua o te wehenga, ka pa ki te katoaONUs.
ONUWhakaahuatanga rama tohu tohu a te taputapu Maama kaakaariki ka mau tonu: Ka weto te hiko o te taputapu: Ka weto te hiko o te taputapu LOS rama: Weto: Ka whiwhi te tauranga PON i te mana whatu noa Maama kaakaariki ka mau tonu: Kua oti te rapunga me te rehitatanga o te taputapu Ka hikoi te rama Kaakaariki: Kaore te taputapu e mahi raraunga Kaore. i runga: Ko te tauranga PON kaore he marama, he iti ake ranei te mana oro i te tairongo manako LAN1, LAN2, LAN3 LAN4 he tauranga hiko, FXS1 he tauranga reo, me te rapu raruraru: Tuatahi, tirohia mehemea kei teONUkei te mahi noa te taputapu (ahakoa he maamaa te rama tohu kei runga i te papanga taputapu). I muri i te mahi o te taputapu, rapua etahi atu take. He rite tonu te tukanga ki te korero i runga ake nei.
