FTTH

1.UHPH Whakangungu Rārangi

I Haina, e rua ngā mahere hanga FTTH matua: te Mahere Whakatakotoranga Taumata Kotahi me te Mahere Whakatakotoranga Taumata Rua. I runga anō i te whakatakotoranga o ngā whakaeke whatu, ka taea te whakarōpū i ēnei ki te whakaeke pokapū me te tohatoha. I tua atu, ka taea te wehe i a rātou i runga anō i ngā āhuatanga whakamahinga ki ngā tono whare maha-papa me ngā tono whare teitei.

2.Whakangungu Whakawehenga Tinoaha

• Tirohanga Whakawehenga Pūnaha

2.1 Whakawehenga Pūnaha (Tāwhata Rawa) Tuhinga

2.2 Whakawehenga Pūnaha (Rawa Matua) Tuhinga

2.3 Wāhi Hangarau

• I te taha OLT (Pūtahi Rākau Matihiko), e whai ake ana i tētahi kapa whakawehenga rākau matihiko. Ko tana take nui he whakapae i ngā pūnaha rākau matihiko i tētahi taha me ngā hīrahi rākau matihiko waewae i tētahi taha, me ngā tuakaupu e hono ai i ngā taha rākau me ngā taha āhua.
• I te tūmomo whakawehenga rākau, e whai ake ana i tētahi kōpaki whakawehenga rākau matihiko kore-pātai. Nō reira ngā pai o te hangarau kore-pātai: e whai wāhi maha ana e rua; e iti haere ana ngā whakatakoto me te kaweanga pātai, e iti haere ana ngā hokohoko ā-tūmomo me ngā hokohoko waewae; me te whakahaere rākau matihiko e tika me te ture.
• I te tūmomo whakawehenga rākau, e whai ake ana i tētahi poaka whakawehenga rākau matihiko kore-pātai, me ngā whakawehenga rākau matihiko kua whakauru ki roto i te poaka mo te whakahaere me te whakatutuki i runga i tētahi paetae.
• I te arawhata, ka whakamahia he pouaka whakahiato hononga tuuturu, hei hono i nga taura whatu tohatoha mai i te waahi urunga kaiwhakamahi me te hononga tuuturu ki te Kaiwhakamahi-mutunga Flat Drop Cable, ka huri i nga taura whatu ki nga taura maturuturu.
• I ngā whare nohanga, e whakamahi ana i tētahi kapa whakawehe raetī, e āhei ana kia takoto ai te ONU, ngā mōhiohanga reo, ngā mōhiohanga rara, ngā pūnaha hokomaha, āpane, taea ai ngā hiahia ratonga whare katoa.
• Tuhipoka: Ko te mahere hanga mō te wehenga pokapū he ōrite mō ngā whare maha-papa me ngā whare teitei. Ko te rerekētanga ko te mea i roto i ngā whare maha-papa, kotahi anake te pouaka hononga hononga hononga honohono o te arawhata e whakatakotoria ana ia waeine, i te mea i roto i nga whare teitei, ka whakatakotoria he pouaka hononga honohono honohono o te arawhata i ia raupapa torutoru.

2.4 Ngā Tuangata Whakamahi me ngā Ataaka

• Ko te wehe haerenga i whakamahi mai ki ngā hapori whare hou, ngā whakatika kāinga kohikohi, ā, ētahi atu tuangata whakamahi. Ki tēnei wā, he tūtohi hanga hoki tēnei, he iti rawa atu me te whakapai pai rawa.
• Ki ngā ture i roto i te whenua pārongo, kāore i whai wāhanga wehe 7 nui rawa i te ODN (Pūnaha Whakawehe Māwhero). Ka whakaiti tēnei tūtohi ki te wehe 5 anake, ka tiakina te mate ara māwhero, ka whakatīnaki i te tokorangi whakawehenga rara.

3.Tirohanga Wehe Whakarite

3.1 Tira Wehe Whakarite (Whare Pūtau)

3.2 Tira Wehe Whakarite (Whare Rāhui)

3.3 Wāhi Hanganga

• Ki te matawhāiti OLT, e whakamahi ana i tētahi rākau whakawehe, me ngā mahi ake kei runga i tēnei.
• Ki te pūtahi rākau tukutuku, mēnā e whakamahia ana te kōpaki pūtahi rākau matihiko kahore i ngā tapa, me ngā paunga pai e whai ake nei.
• Ki te pūtahi whakawehenga rākau matihiko rānei ki roto i te kōrero, e whakamahia ana te poaka whakawehenga rākau matihiko kōhīnga, e āhatu ana i tētahi wehenga nui (hei tauira, 1:32 rānei ko 1:64).
• Ki ngā whare nohanga, e whakamahia ana te poaka taurangi taumata, tae atu ki te whakahaere wehenga poroiti.

3.4 Ngā Tuangata Whakamahi me ngā Ataata

• Ko te wehenga whakawāhi ka whai wāhi tonu ki reira kāore i te wāhi hei whakatū mai i ngā poaka whakawehenga rākau matihiko kahore i ngā tapa, ā, kei reira te whakamahi ā-motu e nui ake ana me te tūpato nui.
• Ki ngā ture iwi o te rorohiko, kāore te ODN i te maha i ngā konekita ohooho e utu ana. Ko tēnei korowai hanga he 5 konekita ohooho, e tiakina ana te mate rākau matihiko me te whakatīnga o te takiwā tuhi.

4. Whakatauara o te Wehenga Poroiti me te Wehenga Whakawāhi

4.1 Wehenga Poroiti

• Ka whakamahi ngā whakawehe mōhuhu i te tirohanga nui ake o ngā tāngata, e hiahiatia ana te whakamahinga.
• Nā ngā pūtango PON OLT (Passive Optical Network) te whakapai i ngā whakawehe mōhuhu, me te whakamahinga nui ake i ngā pūtango PON OLT.
• Ka mutu ngā kākano mōhuhu matua me ngā kākano whakawehenga i tētahi wā, whakarataratia ai te whakahaere raraunga.

4.2 Whakawehe Hokinga

• Ka whakamahi ngā whakawehe mōhuhu i te katoa o ngā tāngata, e hīnati ana te whakamahinga.
• Nā ngā pūtango PON OLT e whakapai ana i ngā whakawehe mōhuhu, me tētahi whakawehe wehewehe i waenganui i ngā 64 rānei ko 32 tāngata, e hīnati ana te whakamahinga o ngā pūtango PON OLT.
• Ka mutu ngā kākano mōhuhu matua me ngā kākano whakawehenga i ngā pūnaha tāngata, whakarerekētia ai te whakahaere raraunga.

5.Pūtake Whakawehe Rua

5.1 Whakawehe Rua (Rohe Pāpori)

5.2 Whakawehe Rua (Rohe Nohopuku)

5.3 Tukanga Whakangāwari

• Ki te wāhanga OLT, ka whakamahi i tētahi rārangi rere mō ngā herenga, me ngā mahi taurite hei whakaatu mai i runga i ngā kōrero mōteatea.
• Ki te pūtahi rākau tukutuku, mēnā e whakamahia ana te kōpaki pūtahi rākau matihiko kahore i ngā tapa, me ngā paunga pai e whai ake nei.
• I te matawhiti tuatahi o te whakawehenga rua-tapa, e whakamahi ana i tētahi kākano whakawehe mōhuhu kore, me ngā whakawehe mōhuhu iti wehe nui kua whakauru ki roto i te kākano mo te whakahaere me te whakariterite i raro.
• I te matawhiti tuarua o te whakawehe, e whakamahi ana i tētahi kākano whakawehe kōhina hei hono i ngā tāhuhu mōhuhu o te tuatahi ki ngā tāhuhu poraka o te whakamotuhake ā-motu, mā ngā whakawehe mōhuhu (wehengā iti), ka whakawhiti i ngā tāhuhu mōhuhu ki ngā tāhuhu poraka.
• Ki roto o ngā whare nohanga, e whakamahi ana i tētahi poipoi whakawehenga rāpoipo, tae atu ki ngā raupapa whakahaere kitea mai i runga.
• Tāpiki: Ko te raupapa hanga hei whakawehenga rua-tapa ko tērā pea te mea e rite ana mō ngā wāhitahanga ā-tāone me ngā wāhitahanga ā-waka.

5.4 Ngā Taiao Whakamahi me ngā Ataata

• Ko te whakawehe rua-tapa he whakamahi tonu hei whakaiti i ngā moni takoha i te take tuatahi mō ngā wāhitahanga e hīnā i te hunga whakamutunga i te take tuatahi, e pāpāke ana ki ngā wāhitahanga waka, arā, ngā hapori rāwhiti rānei.
• Ko te whakawehenga e rua-tahua i roto i te tūmomo ODN, he 7 konekita aktīwa, e whakaaetia ana e ngā paerewa o te rōpū whakapāho.

6.Whakatauira o te Whakawehenga Tahi-tahua ki te Whakawehenga E Rua-tahua

6.1Whakawehenga Tahi-tahua

• Kāore i te pai mo ngā wāhi nohinohi.
• He 5 wāhanga te ODN, e tiakina ana te hokohoko māraroa o te rāngai ā-ao aroha a ka whakatīnaka i te tawariwhi o te tuku raraunga.
• Nui ake te utu hanga.
• Me te pai te whakahaere rārangi.

6.2Whakawehenga E Rua-tahua

• Pai mo ngā wāhi nohinohi me ngā hapori whare pā.
• He 7 nōtu te ODN, e tutuki ana i ngā huringa matua o te hokohoko māraroa.
• I raro rawa te utu hanga tuatahi, engari ka nui ake te utu i te whakamātau i te rātonga ngātahi.
• Ka nui ake te whakarerekētanga me te whakataunga o te whakahaere rārangi.
