1. He aha te XGS-PON?
Ngā mea e ruaXG-PONā, nō te XGS-PONGPONraupapa. Mai i te mahere hangarau, ko XGS-PON te whanaketanga hangarau o XG-PON.
He 10G PON a XG-PON me XGS-PON, ko te rerekētanga matua ko: he PON kore taurite te XG-PON, ko te tere o te hononga/whakaheke o te tauranga PON he 2.5G/10G; he PON taurite te XGS-PON, ko te tere o te hononga/whakaheke o te tauranga PON he 10G/10G.
Ko ngā hangarau PON matua e whakamahia ana i tēnei wā ko te GPON me te XG-PON, ā, he PON kore-taurite ēnei e rua. Nā te mea he kore-taurite ngā raraunga whakarunga/whakaheke o te kaiwhakamahi, hei tauira, ko te toharite o te waka whakarunga o te OLT he 22% noa iho o te waka whakarunga. Nō reira, ko ngā āhuatanga hangarau o te PON kore-taurite e pā ana ki ngā hiahia o ngā kaiwhakamahi. He mea nui ake, he iti te tere o te hononga whakarunga o te PON kore-taurite, he iti te utu mō te tuku i ngā wāhanga pēnei i ngā taiaho ki te ONU, ā, he iti hoki te utu mō ngā taputapu.
Heoi, he rerekē ngā hiahia o ngā kaiwhakamahi. I te pikinga ake o ngā ratonga whakapāho ora me te tirotiro ataata, he maha ake ngā āhuatanga ka aro nui ake ngā kaiwhakamahi ki te whānui o te hononga-ake. Me whakarato ngā raina motuhake e uru mai ana i ngā ara iahiko hononga-ake/hono-iho ōrite. Ka whakatairangahia e ēnei pakihi te hiahia mō te XGS-PON.
2. Te noho tahi o XGS-PON, XG-PON me GPON
Ko te XGS-PON te whanaketanga hangarau o te GPON me te XG-PON, ā, e tautoko ana i te urunga whakauru o ngā momo ONU e toru: GPON, XG-PON me te XGS-PON.
2.1 Te Noho Tahi o XGS-PON me XG-PON
Pērā i te XG-PON, ka whakamahia e te hononga iho o te XGS-PON te tikanga whakapāho, ā, ka whakamahia e te hononga ake te tikanga TDMA.
I te mea he ōrite te roangaru heke me te tere heke o te XGS-PON me te XG-PON, kāore te heke o te XGS-PON e wehewehe i waenga i te XGS-PON ONU me te XG-PON ONU, ā, ka whakapāho te wehewehe whatu i te tohu whatu heke ki te hononga ODN kotahi. Mō ia XG(S)-PON (XG-PON me te XGS-PON) ONU, ka whiriwhiri ia ONU ki te whiwhi i tana ake tohu, ā, ka maka atu i ētahi atu tohu.
Mā te hononga-ake o XGS-PON ka tukuna ngā raraunga e ai ki ngā wā e wātea ana, ā, mā te ONU ka tukuna ngā raraunga i roto i ngā wā e whakaaetia ana e te OLT. Ka tohaina e te OLT ngā wā e wātea ana i runga i ngā hiahia o ngā ONU rerekē me te momo ONU (he XG-PON, he XGS-PON rānei?). I te wā e wātea ana ki te XG-PON ONU, ko te tere tuku raraunga he 2.5Gbps; i te wā e wātea ana ki te XGS-PON ONU, ko te tere tuku raraunga he 10Gbps.
Ka kitea te tautoko ā-tika a XGS-PON i te urunga whakauru me ngā momo ONU e rua, arā, ko XG-PON me XGS-PON.
2.2 Te noho tahi o XGS-PON meGPON
I te mea he rerekē te roangaru hononga-ake/hononga-iho i tērā o te GPON, ka whakamahia e XGS-PON te otinga Combo hei tohatoha i te ODN ki te GPON. Mō te kaupapa o te otinga Combo, tirohia te tuhinga "Kōrero mō te Otinga hei Whakapai ake i te Whakamahinga Rauemi XG-PON o te Poari Kaiohauru Combo".
Ka whakauruhia e te kōwae whatu Combo o XGS-PON te kōwae whatu GPON, te kōwae whatu XGS-PON me te multiplexer WDM.
I te ahunga whakarunga, i muri i te urunga o te tohu whatu ki te tauranga XGS-PON Combo, ka tātarihia e te WDM te tohu GPON me te tohu XGS-PON e ai ki te roangaru, kātahi ka tukuna te tohu ki ngā hongere rerekē.
I te ahunga o te hononga iho, ka whakareatia ngā tohu mai i te hongere GPON me te hongere XGS-PON mā te WDM, ā, ka honoa te tohu whakauru ki te ONU mā te ODN. Nā te rerekētanga o ngā roangaru, ka tīpakohia e ngā momo ONU rerekē ngā roangaru e hiahiatia ana hei whiwhi tohu mā roto i ngā tātari ā-roto.
I te mea e tautoko ana a XGS-PON i te noho tahi me XG-PON, ka tautoko te otinga Combo o XGS-PON i te urunga whakauru o ngā momo ONU e toru a GPON, XG-PON me XGS-PON. Ko te kōwae whatu Combo o XGS-PON e kiia ana hoki ko te kōwae whatu Combo Aratau Toru (ka kiia te kōwae whatu Combo a XG-PON he kōwae whatu Combo aratau-rua nā te mea e tautoko ana i te urunga whakauru o ngā momo ONU e rua a GPON me XG-PON).
3. Te Tūnga o te Mākete
I runga i te pānga o te utu taputapu me te pakeketanga o ngā taputapu, he nui ake te utu taputapu o nāianei o XGS-PON i tō XG-PON. I roto i ēnei, ko te utu wāhanga o OLT (tae atu ki te papa kaiwhakamahi Combo) he tata ki te 20% teitei ake, ā, ko te utu wāhanga o ONU he neke atu i te 50% teitei ake.
Ahakoa me whakarato ngā raina motuhake e tomo mai ana i ngā ara iahiko honohono/hononga-iho, ko te whanonga e whai ake nei tonu te mea e whakahaeretia ana e te nuinga o ngā raina motuhake e tomo mai ana. Ahakoa he maha ake ngā āhuatanga e aro nui ana ngā kaiwhakamahi ki te whānui o te hononga-ake, kāore rawa he take o ngā ratonga kāore e taea te uru atu mā te XG-PON engari me uru atu mā te XGS-PON.
