Me pēhea te whiriwhiri i ngā taputapu PON mō ngā kaupapa whakakotahi FTTH CATV

He uaua tonu ngā taupatupatu mō ngā kaiwhakauru pūnaha me ngā kaihoko ISP i ngā kaupapa whakahou whatunga. He maha ngā tīma hangarau e pāngia ana e ngā ānini o te ao tūturu ina whakamahere ana ki te whakatinana, ki te whakahou rānei i ngā whatunga whatu kore mahi, inā koa mō ngā wāhi e hiahia ana ki ngā tohu whānui kāinga me ngā tohu pouaka whakaata CATV. E ai ki te kōrero whānuitia ana i roto i ngā tuhipoka hangarau ahumahi, ko te taupatupatu roangaru, te mahi DBA me te whakamahinga anō o te ODN o nāianei ngā mea tino uaua i roto i te whakatinanatanga PON ratonga-whakaranu.

Kāore tēnei tuhinga e aro nui ki ngā taipitopito uaua o ngā kawa paparanga-tinana. Engari, ka tukuna he whakataurite mahi me ngā tohutohu whiriwhiri taputapu mō ngā kaupapa FTTH-CATV o te ao tūturu. Ahakoa kei te hanga koe i tētahi whatunga hou, kei te whakahou rānei i ngā hanganga tawhito, mā te mārama ki ngā painga me ngā huakore o ia otinga ka āwhina i a koe ki te karo i ngā hapa utu nui i runga i te papaanga.

Ngā Wero Matua o te Whakatakotoranga PON FTTH‑CATV

I mua i te whakataurite i ngā hua, me wehewehe ngā arai e pā tonu ana ki ngā kaihangarau o te mara. Mā ēnei take mahi ka whakatau ko tēhea paerewa PON e pai ake ana mō tō kaupapa.

Tuatahi,te whakamahinga anō o ngā hanganga tawhitoHe nui ngā pae FTTH o nāianei i hangaia huri noa i te GPON. Ko te tumanako a ngā kaipupuri kaupapa kia mau tonu ngā taura muka taketake, ngā wehewehe me ngā pouaka tohatoha hei tapahi i ngā tahua hanga anō. Heoi, kāore e taea e ngā taputapu katoa te tautoko i te noho tahi maeneene o ngā tohu whatu tawhito me ngā tohu whatu hou. Mā te taurite kore e tika ka puta he putanga ataata ONT tuimotu me te CATV kore pumau.

Tuarua,te pēhanga whānui ratonga maha. Ehara i te mea he urunga ipurangi noa iho ngā pae hou. Ka rere ngā awa IPTV, te paparanga CATV anaro, te reo VoIP me te ipurangi kāinga tere-teitei i runga i te muka kotahi. Mā te whakaritenga whānui ngoikore ka puta he wheako ataata pōturi, ka waiho hei pūtake amuamu nui mai i ngā kaiohauru whakamutunga.

Tuatoru,huringa haumi ā-muaMe whakataurite e ngā kaiwhakahaere me ngā kaiwhakauru te utu o te kaupapa o nāianei me te roanga o te ratonga 5-8 tau. Mēnā he iti rawa ngā taputapu e hiahiatia ana, ka whakakapia katoatia pea i roto i ētahi tau, engari ko te hoko taputapu nui rawa ka waiho hei maumau moni koretake.

Whakataurite taha-ki-taha: GPON vs XGS‑PON mō ngā horopaki FTTH‑CATV

Tuemi Aromatawai	OLT‑G16V (GPON OLT Parakore)	XGSPON‑08P (XG(S)‑PON Whakakotahi OLT)
Reiti Tauranga PON	Raro 2.488Gbps / Whakaraunga 1.244Gbps (ITU‑T G.984)	10Gbps ōrite (aratau XGS‑PON); hototahi whakamuri 2.488G/1.244G (aratau GPON)

Te Whakamahinga Anō o te GPON ODN o nāianei	Ka mahi tahi me ngā wehewehe GPON paerewa; kāore he tātari tāpiri e hiahiatia ana mō te whatunga GPON parakore	Tautoko ana i te GPON ODN o nāianei; e hiahiatia ana he tātari noho tahi o waho mō te whakatinanatanga muka tahi GPON/XGS‑PON whakauru
Hototahi Paparua CATV 1550nm	Tautoko ana i te 1550nm CATV overlay; he whānuitia te whakatinanatanga mō ngā kaupapa FTTH‑CATV triple‑play	Tautoko ana i te 1550nm CATV overlay; me whai whakaaro ki te wehenga roangaru i raro i te mahi aratau whakauru
Tauwhāititanga Wehewehenga	Te mōrahi taputapu 1:128; 1:64 e taunakitia ana mō te ratonga whānui pumau + CATV e whakahaere ana i ngā ratonga whakauru	Te mōrahi taputapu 1:256; 1:64–1:128 e taunakitia ana; me whakamātautau katoa te whakaiti hononga mō ngā horopaki CATV overlay
Ngā Horopaki Whakatakotoranga Whāinga Noa	FTTH taiwhenua nui, whatunga noho hapori, kaupapa takaro-toru e aro nui ana ki te utu me ngā kaiohauru GPON nui	Ngā whare noho kiato nui, ngā puni hōtēra, ngā whatunga hinonga, ngā whatunga tere-teitei hou e hiahia ana ki te whānui o te hononga 10G ā-mua

I te arotake i ngā kōwhiringa taputapu, kaua e arotahi noa ki ngā tawhā tere noa iho. Mō ngā kaupapa whakakotahi FTTH‑CATV, me aro nui ki te kaha tātari whatu kua whakauruhia me te mahi whakarite DBA oNgā taputapu 10G PON OLTHe maha ngā taputapu iti te utu kei te mākete e whakamahi ana i ēnei kōwae e rua, ā, ka hua ake te whakatio pinepine o te ataata i raro i te kawenga ratonga wā-tūturu taumaha.

He Aratohu Whakatau: Ko tēhea Otinga me Kōwhiri e Koe?

Kōwhiria te GPON mēnā:

Ko tāu kaupapa he whakatinana i te whatunga whānui o te taiwhenua, he whakahoutanga iti rānei te tahua. Kua pumau kē te whatunga ODN o nāianei, kei raro iho i te 300Mbps te tono whānui o ngā kaiohauru mō ia whare, ā, ko te CATV overlay te hiahia matua māu. He nui ngā wheako whakatinanatanga kua whakamanahia e te mara kua kohia e te GPON. He ngāwari te whiwhi i ngā wāhanga e manawapa ana me ngā rauemi tiaki i ngā mākete o te ao.

Kōwhiria te XGS‑PON mēnā:

Kei te mahi koe i ngā whare noho nui, i ngā puni hōtēra nui, i ngā rohe noho arumoni rānei. Me whakamahi te hunga whakamahi mutunga i te whānui o te whatunga gigabit, ā, e tumanakohia ana ka mahi te kaha o te whatunga mō ngā tau 6-8 e whai ake nei. I tēnei wā,ONT hototahi ki te XGS‑PON me te tauranga CATVKa puta he uara mō te wā roa. Kia maumahara: ko te GPON me te XGS‑PON whakaranu e rere ana i runga i te muka kotahi me whai kōwae tātari whai tohu i roto i te OLT, kaua e pekehia tēnei whirihoranga hei penapena utu mō te wā poto.

Ārai i te whakatinanatanga hē

Kaua e akiaki i te whakatinanatanga o te XGS‑PON i roto i te aratau whakaranu mēnā kāore i te wātea i tō rōpū i runga i te papaanga te wheako patuiro PON e tika ana. Mā te pokanoa o te roangaru motuhake ka puta he hapa uaua ki te whakaputa anō, ka pau te nui o te kaha o te tangata i muri i te hoko.

Ngā Akoranga Mai i te Mahi Kaupapa o te Ao Tūturu

I whakamahere tētahi kaiwhakauru pūnaha kei te Tonga-mā-rāwhiti i te whakahoutanga whatunga mō tētahi wāhi hararei takutai. I te tīmatanga, i whakaarohia e te tīma te whakatinana tika i te aratau whakauru XGS‑PON ki runga i te whatunga muka GPON taketake. Whai muri i te arotake i ngā mōrearea hangarau kua tuhia e te umanga, i whakahaerehia e rātou ngā whakamātautau mara iti i te tuatahi. I whakaatuhia e ngā whakamātautau tuatahi te piki me te heke o te tohu me te kore he wae tātari tika. Hei whakamutunga, i whiriwhiria e rātou ngā taputapu OLT me ngā tātari whatu noho tahi kua whakauruhia, me te pupuri i te nuinga o ngā wāhanga ODN taketake me te tāpiri i te ratonga XGS‑PON mō ngā whare manuhiri papai, me te pupuri tonu i te GPON mō ngā rohe whakamahinga whānui. I wehewehea e tēnei whakatinanatanga te tahua, te pumau me te kaha whakawhānui a meake nei.
