I roto i te nuinga, ko te mana marama o te whatu whatu transceiver or optical module is as follows: multimode is between 10db and -18db; Ko te aratau kotahi ko te 20km i waenga i -8db me -15db; me te aratau kotahi he 60km kei waenganui i -5db me -12db i waenga. Engari ki te puta te mana maramara o te kaitahuri muka i waenga i te -30db me te -45db, katahi pea ka raru tenei kaitahuri muka.

Me pehea te whakatau mehemea he raru kei te kaiwhakawhiti muka?

(1) Tuatahi, tirohia mena kei te ka te rama tohu o te kaikawe muka whatu me te rama tohu o te tauranga takirua miro.

a. Mena kua kore te tohu FX o te kaiwhakawhitiwhiti, whakaūhia mena he hononga-whakawhiti te hononga muka? Ko tetahi pito o te peke muka ka hono whakarara; ko tetahi atu pito e hono ana ki te aratau ripeka.

b. Mena kei te noho te tohu tauranga whatu (FX) o te A transceiver ka mutu te tohu tauranga (FX) o te B transceiver, ko te he kei te taha o te A transceiver: ko tetahi pea ko: He whakawhiti whatu (TX) he kino te tauranga na te mea karekau te tauranga whatu (RX) o te kaiwhakawhitiwhiti B e whiwhi i te tohu whatu; Ko tetahi atu pea ko: he raruraru kei tenei hononga muka o te tauranga whakawhiti whatu o te A transceiver (TX) (ka pakaru te taura whatu, te peke whatu ranei).

c. Kua weto te tohu takirua takahuri (TP). Me mohio kei te he te hononga takirua, kei te he ranei te hononga? Tena koa, whakamahia he kaiwhakamatau haere tonu ki te whakamatautau (engari, me tatari nga rama tohu takirua o etahi whakawhiti kia honoa te hononga muka).

d. E rua nga tauranga RJ45 etahi o nga kaiwhakawhitiwhiti: (ToHUB) e tohu ana ko te raina hono ki te whakawhiti he raina tika; (ToNode) e tohu ana ko te raina hono ki te whakawhiti he raina whakawhiti.

e. Ko etahi o nga makawe makawe he pana MPR i te taha: ko te tikanga ko te raina hononga ki te whakawhiti he raina tika; Whakawhiti DTE: ko te raina hononga ki te whakawhiti he aratau whakawhiti.

(2) Ahakoa kua pakaru te taura whatu me te peke muka whatu

a. Hononga taura whatu me te kitenga momotu: whakamahia te rama taiaho, te ra, te tinana marama ki te whakamarama i tetahi pito o te hononga taura whatu, te hono ranei; tirohia mena he marama kei tera pito? Mena he marama ka kitea, ka tohu kaore i pakaru te taura whatu.

b. Te kitenga o te hononga muka whatu: whakamahia te rama laser, te ra, me etahi atu hei whakamarama i tetahi pito o te peke muka; tirohia mena he marama kei tera pito? Mena ka kitea te marama, kaore i pakaru te peke muka.

(3) Mehemea kei te he te aratau haurua/taarua katoa

Ko etahi o nga kaiwhakawhitiwhiti he whakawhiti FDX ki te taha: te taapiri katoa; Whakawhiti HDX: haurua matarua.

(4) Whakamatau me te mita hiko whatu

Ko te mana marama o te whakawhiti muka whatu whatu ranei kōwae i raro i nga tikanga noa: maha-aratau: i waenganui i -10db me -18db; aratau kotahi 20 kiromita: i waenganui i -8db me -15db; aratau kotahi 60 kiromita: i waenganui i -5db me -12db ; Mena kei waenganui i te -30db-45db te mana marama o te kaitahuri muka, ka taea te whakatau he raru kei tenei kaihurihuri muka.
