Ngā Kupumatua: te pikinga ake o te kaha o te whatunga whatu, te auahatanga hangarau tonu, te whakarewatanga haere o ngā kaupapa whakamātautau atanga tere-teitei
I tēnei wā o te mana rorohiko, me te kaha o te akiaki i ngā ratonga me ngā tono hou, kei te haere tonu te auaha me te whanaketanga o ngā hangarau whakapai ake i te kaha maha-ahu pēnei i te tere tohu, te whānui o te hihi e wātea ana, te aratau maha-whakawhiti, me ngā pāpāho tuku hou.
Tuatahi, mai i te tirohanga o te pikinga o te tere tohu atanga, o te hongere rānei, ko te tauine o10G PONKua whānuitia ake te whakatinanatanga i roto i te whatunga urunga, kua tau te nuinga o ngā paerewa hangarau o te 50G PON, ā, he kaha te whakataetae mō ngā otinga hangarau PON 100G/200G; ko te whatunga tuku e whakahaerehia ana e te Whanuitanga Tere 100G/200G, e matapaetia ana ka piki ake te ōwehenga o te tere hononga ā-roto, ā-waho rānei o te pokapū raraunga 400G, i te wā e whakatairangahia ana te 800G/1.2T/1.6T me ētahi atu whanaketanga hua tere teitei me te rangahau paerewa hangarau, ā, e matapaetia ana ka tukuna e ngā kaihanga upoko whakawhitiwhiti whatu o tāwāhi he hua maramara tukatuka DSP tere teitei ake 1.2T, he mahere whanaketanga tūmatanui rānei.
Tuarua, mai i te tirohanga o te whānuitanga e wātea ana mō te tuku, ko te whakawhānui haere o te roopu-C arumoni ki te roopu C+L kua waiho hei otinga whakakotahi i roto i te umanga. E matapaetia ana ka piki haere tonu te mahi tuku taiwhanga i tēnei tau, ā, i te wā kotahi ka haere tonu te rangahau i ngā whānuitanga whānui pēnei i te roopu S+C+L.
Tuatoru, mai i te tirohanga o te whakarea tohu, ka whakamahia te hangarau whakarea wehewehe ātea hei otinga roa mō te aukati o te kaha tuku. Ka haere tonu te whakatinanatanga me te whakawhānui i te pūnaha taura ruku moana e hangai ana ki te whakanui haere i te maha o ngā takirua muka whatu. I runga i te whakarea aratau me/ranei te whakarea maha Ka haere tonu te ako hohonu i te hangarau o te whakarea matua, me te arotahi ki te whakanui ake i te tawhiti tuku me te whakapai ake i te mahi tuku.
Kātahi, mai i te tirohanga o ngā pāpāho tuku hou, ka noho ko te muka whatu tino iti-ngaronga G.654E hei whiringa tuatahi mō te whatunga pūtake me te whakapakari i te whakatinanatanga, ā, ka haere tonu tana ako mō te muka whatu wehewehe-wāhi (taura). Ko te whānuitanga, te whakaroa iti, te pānga kore-raina iti, te marara iti, me ētahi atu painga maha kua waiho hei arotahi a te umanga, i te mea kua arotauhia ake te ngaronga tuku me te tukanga tuhi. Hei tāpiri, mai i te tirohanga o te manatoko hangarau me te pakeketanga hua, te aro ki te whanaketanga umanga, me ētahi atu, e tumanakohia ana ka whakarewahia e ngā kaiwhakahaere o te whare ngā whatunga ora o ngā pūnaha tere-teitei pēnei i te mahi tawhiti-roa DP-QPSK 400G, te noho tahi aratau-rua 50G PON me ngā kaha tuku ōrite i te tau 2023. Mā te mahi manatoko whakamātautau ka manatokohia anō te pakeketanga o ngā hua atanga tere-teitei noa, ā, ka whakatakoto i te turanga mō te whakatinanatanga arumoni.
Hei whakamutunga, nā te whakapainga o te tere atanga raraunga me te kaha whakawhiti, kua noho te whakaurunga teitei ake me te iti o te whakapaunga pūngao hei whakaritenga whanaketanga o te waeine whatu o te waeine matua o te whakawhitiwhiti whatu, inā koa i roto i ngā horopaki tono pokapū raraunga noa, ina tae te kaha whakawhiti ki te 51.2Tbit/s Me runga ake, ko te momo whakauru o ngā waeine whatu me te tere o te 800Gbit/s Me runga ake ka tūtaki pea ki te whakataetae noho tahi o te mono me te mōkihi whakaahua-hiko (CPO). E matapaetia ana ka haere tonu ngā kamupene pēnei i a Intel, Broadcom, me Ranovus ki te whakahou i roto i tēnei tau. Haunga ngā hua me ngā otinga CPO o nāianei, ā, ka whakarewa pea i ngā tauira hua hou, ka kaha hoki ētahi atu kamupene hangarau whakaahua-hiko ki te whai i te rangahau me te whanaketanga, ka aro nui rānei ki taua mea.
Hei tāpiritanga, mō te hangarau whakauru photonic e hangai ana ki ngā tono mōrahi whatu, ka noho tahi te photonics silicon me te hangarau whakauru semiconductor III-V, i te mea he tere te whakauru o te hangarau photonics silicon, he tere teitei, he pai hoki te hototahi ki ngā tukanga CMOS o nāianei. Kua āta whakamahia te photonics silicon ki ngā mōrahi whatu mono-tawhiti me te tawhiti poto, ā, kua noho ko ia te otinga tūhura tuatahi mō te whakaurunga CPO. Kei te tino tumanako te umanga mō te whanaketanga o te hangarau photonics silicon ā muri ake nei, ā, ka tukuna ngātahitia hoki tana tūhuratanga tono ki te rorohiko whatu me ētahi atu mara.
