I le vaitau o le malosi faakomepiuta, faatasi ai ma le malosi malosi o le tele o auaunaga fou ma talosaga, tele-dimensional gafatia faʻaleleia tekinolosi e pei ole fua faʻailoga, avanoa lautele lautele, telexing mode, ma faʻasalalauga faʻasalalau fou o loʻo faʻaauau pea ona faʻafouina ma atinaʻe.
Muamua lava, mai le va'aiga o le feso'ota'iga po'o le fa'atupuina o fa'ailo alalaupapa, le fua o le10G PONfaʻapipiʻiina i le fesoʻotaʻiga avanoa ua faʻalauteleina, o tulaga faʻapitoa o le 50G PON ua masani ona faʻamautuina, ma o le tauvaga mo 100G / 200G PON faʻamatalaga faʻapitoa e malosi; o le fesoʻotaʻiga fesoʻotaʻiga o loʻo pulea e le 100G / 200G saoasaoa Faʻalauteleina, o le vaega o le 400G data center i totonu poʻo fafo fua fesoʻotaʻiga o loʻo faʻamoemoeina e faʻatupulaia tele, ae 800G / 1.2T / 1.6T ma isi maualuga maualuga le atinaʻeina o oloa ma suʻesuʻega faʻapitoa faʻatekinisi o loʻo faʻalauiloaina faʻatasi, ma e sili atu tagata gaosi oloa fesoʻotaʻiga mai fafo o loʻo faʻamoemoeina e tuʻuina atu fua faʻatatau 1.2T atinaʻe atinaʻe DSP poʻo le maualuga atu.
Lona lua, mai le va'aiga o alaleo avanoa mo le fa'asalalauina, o le faasolosolo malie o le fa'alauteleina o le C-band fa'atau pisinisi i le C + L fa'aili ua avea ma fofo fa'afeso'ota'i i le alamanuia. O lo'o iai le fa'amoemoe o le a fa'aauau pea le fa'aleleia atili o le fa'atinoga o feso'ota'iga falesu'esu'e i lenei tausaga, ma o le taimi fo'i lea e fa'aauau pea su'esu'ega i alaleo lautele e pei o le S+C+L band.
Lona tolu, mai le va'aiga o fa'alilolilo fa'alilolilo, avanoa vaeluaga multiplexing tekonolosi o le a fa'aaogaina e avea o se fofo umi i le bottleneck o le gafatia felauaiga. O le faiga o le uaea i lalo o le sami e fa'avae i luga o le faasolosolo malie o le fa'ateleina o le numera o paipa fiber opitika o le a fa'aauau pea ona fa'apipi'iina ma fa'alauteleina. Fa'avae ile fa'aogaina ole tele ma/po'o le tele ole a fa'aauauina su'esu'ega loloto ole tekonolosi ole tele ole tele, fa'atatau ile fa'ateleina ole mamao ole fa'asalalauga ma fa'aleleia le fa'atinoga o felauaiga.
Ona, mai le vaaiga o faasalalauga fou faasalalauga, G.654E ultra-maualalo-loss opitika fiber o le a avea ma filifiliga muamua mo le ogalaau fesootaiga ma faamalosia deployment, ma o le a faaauau pea ona suesue mo avanoa-vaega multiplexing fiber optika (cable). Alaleo, tuai tuai, maualalo nonlinear aafiaga, taape maualalo, ma isi tulaga lelei tele ua avea ma taulaiga o le alamanuia, ae o le aveesea ma le faagasologa o ata ua sili atu optimized. I le faaopoopo atu, mai le vaaiga o tekinolosi ma oloa matua faamaoniga, atinae o alamanuia gauai atu, ma isi., kamupani i totonu o le atunuu ua faamoemoe e faalauiloa fesootaiga ola o faiga saosaoa maualuga e pei o le DP-QPSK 400G faatinoga umi-mamao, 50G PON lua-mode coexistence ma symmetrical transmission gafatia i 2023 O le suʻega maualuga-vave galuega faʻataʻitaʻiina atili faʻamaonia le faʻatautaia o oloa faʻapisinisi ma faʻataʻitaʻiga faʻapitoa fa'atinoina.
Ma le mea mulimuli, faʻatasi ai ma le faʻaleleia atili o le faʻaogaina o fesoʻotaʻiga faʻamatalaga ma le gafatia o le fesuiaiga, o le tuʻufaʻatasia maualuga ma le faʻaitiitia o le faʻaaogaina o le malosi ua avea ma mea e manaʻomia mo le atinaʻeina o le module opitika o le iunite faavae o fesoʻotaʻiga faʻapitoa, aemaise lava i faʻataʻitaʻiga masani o faʻamatalaga o faʻamatalaga, pe a oʻo atu le gafatia o le ki 51.2Tbit / s Ma luga atu, o le tuʻufaʻatasia o masini faʻapipiʻi ma se fua faatatau o le 800Gbit / s ma luga e mafai ona faʻafeagai ma le faʻataʻitaʻiga faʻapipiʻi (CPOGO ma luga atu e mafai ona faʻafeiloaʻi le faʻaogaina o ata faʻapipiʻi). O loʻo faʻamoemoeina o kamupani e pei o Intel, Broadcom, ma Ranovus o le a faʻaauau pea ona faʻafouina i totonu o lenei tausaga I le faʻaopoopoga i oloa CPO o loʻo i ai nei ma fofo, ma e ono faʻalauiloaina ni faʻataʻitaʻiga fou, o isi kamupani faʻatekonolosi photonics o le a tulitatao ma le malosi i suʻesuʻega ma atinaʻe pe faʻalogo lelei i ai.
E le gata i lea, e tusa ai ma tekinolosi faʻapipiʻi photonic e faʻavae i luga o talosaga module opitika, o le a ola faʻatasi le photonics silicon ma le III-V semiconductor integration technology, ona o le silicon photonics technology e maualuga le tuʻufaʻatasia, maualuga le saoasaoa, ma le fetaui lelei ma le CMOS o loʻo i ai nei. O loʻo faʻamoemoeina le alamanuia e uiga i le atinaʻeina o tekonolosi photonics i le lumanaʻi, ma o lana suʻesuʻega faʻaogaina i komepiuta faʻapitoa ma isi matāʻupu o le a faʻatautaia foi.
