Na te whanaketanga o te aoiao me te hangarau, kei te tere haere te tere o te whakamohiotanga i nga taone nui, kei te piki haere nga whakaritenga mo te hangarau korero. Ko nga muka whatu kei te rongonui haere i roto i te whakawhitiwhiti korero na te mea he pai ake te tere o te tuku tere, te tawhiti roa, te haumaru me te pumau, te aukati i te pokanoa, me te whakawhanui watea. Ko te whiriwhiri tuatahi i te wa e whakatakoto ana. He maha nga wa ka kite tatou ko nga whakaritenga tuku raraunga tawhiti-tawhiti i roto i te hanga kaupapa mohio ko te whakamahi i te tuku muka whatu. Ko te hononga i waenga i tenei ka hiahia ki nga waahanga whatu me nga whakawhiti whakawhiti muka.
Ko te rereketanga i waenga i te waahanga whatu me te whatu whatu transceiver:
1.Ko te kōwae whatu he kōwae mahi, he apatoko ranei, he taputapu hāngū e kore e taea te whakamahi anake. Ka whakamahia noa i rotowhakakāme nga taputapu whai mokamoka kōwae whatu; he taputapu mahi te kaiwhakawhiti muka whatu me te mahi motuhake Ka taea te whakamahi anake te taputapu me te hiko hiko;
2.Ka taea e te kōwae whatu ake te whakangwari i te whatunga me te whakaiti i te waahi o te kore, me te whakamahi i nga transceivers muka whatu ka taapiri atu i te maha o nga taputapu, ka nui ake te tere o te ngoikoretanga me te noho ki te waahi rokiroki o te rūnanga, kaore i te ataahua;
3.Ko te kōwae whatu e tautoko ana i te whakawhiti wera, a he ngawari te whirihoranga; ko te whakawhiti i te muka whatu he ahua pumau, a ko te whakakapi me te whakahou ka nui ake te raruraru atu i te waahanga mata;
4. He nui ake te utu o nga waahanga mataiti atu i nga kaiwhakawhitiwhiti muka whatu, engari he tino pumau, kaore i te pakaru noa; He ohaoha, he whai kiko hoki nga kaiwhakawhitiwhiti muka whatu, engari he maha nga mea penei i te urutau hiko, te mana muka, me te mana taura whatunga me whai whakaaro. E 30% pea te ngaronga tuku;
I tua atu, kia whai whakaaro ki te maha o nga waahanga i te wa e hono ana i te kōwae muka whatu me te whatu whatu transceiver: me rite te roangaru me te tawhiti tuku, hei tauira, ko te roangaru ko 1310nm ranei 850nm i te wa ano, ko te tawhiti tuku he 10km ; ko te peke muka me te poaka poaka me rite te atanga ki te hono, Ko te tikanga, ka whakamahia e te kaiwhakawhitiwhiti muka whatu te tauranga SC, a ka whakamahia e te kōwae whatu te tauranga LC. Ko tenei tohu ka akiaki i te whiriwhiringa o te momo atanga i te wa e hoko ana. I te wa ano, me rite te tere o te whakawhiti i te muka whatu me te waahanga mata, hei tauira, ko te Gigabit transceiver e rite ana ki te 1.25G optical module, 100M ki 100M, me te Gigabit ki Gigabit; te momo muka whatu o te kōwae whatu me rite, muka kotahi ki te muka kotahi, muka rua ki muka rua.
