Ko te muka ki te kāinga (FTTH) he pūnaha e tāuta ana i ngā muka whatu mai i tētahi pūwāhi pokapū tika ki roto i ngā whare takitahi pēnei i ngā kāinga me ngā whare noho. Kua roa te whakatinanatanga o te FTTH i mua i te whakamahinga a ngā kaiwhakamahi i ngā muka whatu hei utu mō te parahi mō te urunga Ipurangi whānui.
E rua ngā huarahi matua hei whakatinana i tētahi whatunga FTTH tere-teitei:whatunga whatu hohe(AON) me te kore mahiwhatunga whatu(PON).
Nā, ko ngā whatunga AON me PON: he aha te rerekētanga?
He aha te whatunga AON?
He hanganga whatunga pūwāhi-ki-pūwāhi te AON, kei ia kaiohauru tana ake aho muka whatu e mutu ana i tētahi pūwhakakotahi whatu. Kei roto i te whatunga AON ngā taputapu whakawhiti hiko pēnei i ngā pouara, ngā pūhui whakawhiti rānei hei whakahaere i te tohatoha tohu me te tohu aronga ki ngā kiritaki motuhake.
He maha ngā huarahi e whakakāhia ai, e whakawetohia ai ngā pana hei tuku i ngā tohu e haere mai ana, e haere atu ana ki ngā wāhi e tika ana. Mā te whakawhirinaki o te whatunga AON ki te hangarau Ethernet ka māmā ake te mahi tahi i waenga i ngā kaiwhakarato. Ka taea e ngā kaiohauru te whiriwhiri i ngā taputapu e whakarato ana i ngā tere raraunga e tika ana, me te whakanui ake i a rātou anō i te pikinga ake o ā rātou hiahia me te kore e hiahia ki te whirihora anō i te whatunga. Heoi, me whakamahi ngā whatunga AON i te iti rawa i te kotahi te kaiwhakakotahi pana mō ia kaiohauru.
He aha te whatunga PON?
He rerekē te PON i ngā whatunga AON, he hoahoa whatunga tohu-ki-maha-ira e whakamahi ana i ngā wehewehe kore mahi hei wehewehe me te kohikohi i ngā tohu whatu. Mā ngā wehewehe muka ka taea e te whatunga PON te mahi ki ngā kaiohauru maha i roto i te muka kotahi, me te kore e hiahiatia te whakatakoto muka motuhake i waenga i te pokapū me te kaiwhakamahi mutunga.
E ai ki te ingoa, kāore ngā whatunga PON e whakauru ana i ngā taputapu whakawhiti motuka, ā, kāore hoki he paihere muka tiritahi mō ētahi wāhanga o te whatunga. Ko ngā taputapu hohe anake e hiahiatia ana i ngā pito pūtake me ngā pito whiwhi o te tohu.
I roto i tētahi whatunga PON noa, ko te wehewehe PLC te mea matua. Ka whakakotahi ngā taputapu muka whatu i ngā tohu whatu maha ki tētahi putanga kotahi, ka tangohia rānei e ngā taputapu muka whatu tētahi tāuru whatu kotahi ka tohatoha ki ngā putanga takitahi maha. He rua ngā ahunga o ēnei taputapu mō te PON. Kia mārama ai, ka taea te tuku i ngā tohu muka whatu ki raro mai i te tari matua hei whakapāho ki ngā kaiohauru katoa. Ka taea te tuku i ngā tohu mai i ngā kaiohauru ki runga, ka whakakotahi hei muka kotahi hei whakawhitiwhiti kōrero ki te tari matua.
Whatunga AON me PON: Ngā Rerekētanga me ngā Kōwhiringa
Ko ngā whatunga PON me AON te pou tuara o te pūnaha FTTH, e āhei ai te tangata me ngā pakihi ki te uru atu ki te Ipurangi. I mua i te whiriwhiri i tētahi PON, AON rānei, he mea nui kia mārama ki ngā rerekētanga i waenganui i a rāua.
Tohatoha Tohu
Mō ngā whatunga AON me PON, ko te rerekētanga matua i waenganui i a rāua ko te huarahi e tohatohahia ai te tohu whatu ki ia kiritaki i roto i te pūnaha FTTH. I roto i te pūnaha AON, he paihere muka motuhake ā ngā kaiohauru, e āhei ai rātou ki te uru atu ki te whānui o te whatunga kotahi, kaua ki te whatunga tiritahi. I roto i te whatunga PON, ka tohaina e ngā kaiohauru tētahi wāhanga o te paihere muka o te whatunga i roto i te PON. Nō reira, ka kitea pea e te hunga e whakamahi ana i te PON he puhoi ake tā rātou pūnaha nā te mea he rite te whānui o te whatunga e tohaina ana e ngā kaiwhakamahi katoa. Mena ka puta he raruraru i roto i te pūnaha PON, ka uaua pea te kimi i te pūtake o te raruraru.
Ngā utu
Ko te whakapaunga nui rawa atu i roto i tētahi whatunga ko te utu mō te whakakaha i ngā taputapu me te tiaki. Ka whakamahia e te PON ngā taputapu kore mahi e hiahia ana ki te tiaki iti ake, ā, kāore he pūtake hiko e hiahiatia ana i te whatunga AON, he whatunga hohe. Nō reira, he iti ake te utu o te PON i te AON.
Te Tawhiti me ngā Taupānga o te Kapinga
Ka taea e te AON te hipoki i te tawhiti tae atu ki te 90 kiromita, engari ko te PON ia e herea ana e ngā taura muka whatu tae atu ki te 20 kiromita te roa. Ko te tikanga me tata atu ngā kaiwhakamahi PON ki te tohu pūtake mai i te taha whenua.
Hei tāpiritanga, mēnā e pā ana ki tētahi tono, ratonga rānei, me whai whakaaro ki ētahi atu āhuatanga. Hei tauira, mēnā ka whakatinanahia ngā ratonga RF me te ataata, ko te PON anake te otinga whai hua. Heoi, mēnā he Ipurangi-Kawa ngā ratonga katoa, he pai pea te PON, te AON rānei. Mēnā he tawhiti ake ngā tawhiti, ā, he raruraru pea te whakarato hiko me te whakamatao ki ngā wāhanga hohe i te mara, ko te PON pea te kōwhiringa pai rawa atu. Mēnā rānei he arumoni te kiritaki ūnga, he maha rānei ngā whare noho kei roto i te kaupapa, he pai ake pea te whatunga AON.
Whatunga AON me te PON: Ko tēhea FTTH e pai ana ki a koe?
I te wā e whiriwhiri ana i waenga i te PON, i te AON rānei, he mea nui kia whakaarohia ngā ratonga ka tukuna mā te whatunga, te āhua o te whatunga whānui, me ko wai ngā kiritaki matua. He maha ngā kaiwhakahaere kua whakamahi i te ranunga o ngā whatunga e rua i roto i ngā āhuatanga rerekē. Heoi, i te mea kei te tipu haere tonu te hiahia mō te mahi tahi me te tauine whatunga, kei te kaha ngā hoahoa whatunga ki te tuku i tētahi muka kia whakamahia hei whakawhitiwhiti i roto i ngā tono PON, AON rānei kia tutuki ai ngā whakaritenga o ngā hiahia ā muri ake nei.
