Mawu Ofunika: Kuwonjezeka kwa mphamvu ya netiweki ya kuwala, luso lamakono lopitilira, mapulojekiti oyendetsa mawonekedwe othamanga kwambiri ayambitsidwa pang'onopang'ono
Mu nthawi ya mphamvu ya makompyuta, ndi mphamvu yamphamvu ya mautumiki ndi mapulogalamu ambiri atsopano, ukadaulo wowongolera mphamvu zambiri monga kuchuluka kwa ma signal, spectral width yomwe ilipo, multiplexing mode, ndi ma transmission media atsopano akupitilizabe kupanga zatsopano ndikukula.
Choyamba, kuchokera pakuwona kuwonjezeka kwa chiwongolero cha mawonekedwe kapena chizindikiro cha njira, kukula kwa10G PONKugwiritsidwa ntchito kwa netiweki yolumikizira kwakulitsidwa kwambiri, miyezo yaukadaulo ya 50G PON yakhazikika nthawi zambiri, ndipo mpikisano wa mayankho aukadaulo a 100G/200G PON ndi woopsa; netiweki yotumizira mauthenga ikulamulidwa ndi Kukula kwa liwiro la 100G/200G, kuchuluka kwa kulumikizana kwa data pakati pa 400G mkati kapena kunja kukuyembekezeka kuwonjezeka kwambiri, pomwe 800G/1.2T/1.6T ndi chitukuko china chapamwamba cha zinthu ndi kafukufuku waukadaulo zikulimbikitsidwa pamodzi, ndipo opanga mitu yolumikizirana yakunja akuyembekezeka kutulutsa zinthu za 1.2T kapena zapamwamba kwambiri zogwirira ntchito za DSP kapena mapulani otukula anthu.
Kachiwiri, poganizira za sipekitiramu yomwe ilipo yotumizira mauthenga, kukula pang'onopang'ono kwa C-band yamalonda kupita ku C+L band kwakhala njira yolumikizirana mumakampani. Akuyembekezeka kuti magwiridwe antchito a labotale otumizira mauthenga apitilizabe kusintha chaka chino, komanso nthawi yomweyo kupitiliza kufufuza pa sipekitiramu yokulirapo monga S+C+L band.
Chachitatu, poganizira za kuchulukitsa ma signal, ukadaulo wogawa ma space division multiplexing udzagwiritsidwa ntchito ngati njira yothetsera vuto la mphamvu yotumizira ma signal. Dongosolo la chingwe cha pansi pamadzi lozikidwa pa kuchulukitsa pang'onopang'ono kwa ma optical fiber pair lidzapitiliza kugwiritsidwa ntchito ndikukulitsidwa. Potengera kuchulukitsa ma mode ndi/kapena ma multiple Ukadaulo wa core multiplexing upitiliza kuphunziridwa mozama, kuyang'ana kwambiri pakuwonjezera mtunda wotumizira ma signal ndikuwongolera magwiridwe antchito otumizira ma signal.
Kenako, kuchokera ku malingaliro a njira zatsopano zotumizira mauthenga, G.654E ultra-low-loss optical fiber idzakhala chisankho choyamba cha netiweki ya trunk ndikulimbitsa kutumizidwa, ndipo ipitiliza kuphunzira za ulusi wochulukitsa mawaya (chingwe) wa space-division. Spectrum, kuchedwa kochepa, zotsatira zochepa zosalunjika, kufalikira kochepa, ndi maubwino ena ambiri akhala cholinga cha makampaniwa, pomwe njira yotaya mawaya ndi zojambula zakonzedwanso. Kuphatikiza apo, kuchokera ku malingaliro aukadaulo ndi kutsimikizira kukhwima kwa zinthu, chidwi cha chitukuko cha mafakitale, ndi zina zotero, ogwira ntchito m'nyumba akuyembekezeka kuyambitsa maukonde amoyo a machitidwe othamanga kwambiri monga DP-QPSK 400G kutalika, 50G PON dual-mode coexistence ndi symmetrical transmission capabilities mu 2023 Ntchito yotsimikizira mayeso imatsimikiziranso kukhwima kwa zinthu zodziwika bwino zolumikizirana mwachangu ndikuyika maziko otumizira malonda.
Pomaliza, chifukwa cha kusintha kwa kuchuluka kwa deta ndi mphamvu yosinthira, kuphatikiza kwakukulu komanso kugwiritsa ntchito mphamvu zochepa kwakhala zofunikira pakukula kwa gawo la kuwala la gawo loyambira la kulumikizana kwa kuwala, makamaka m'malo ogwiritsira ntchito deta, pomwe mphamvu yosinthira imafika pa 51.2Tbit/s Ndipo pamwambapa, mawonekedwe ophatikizika a ma module opangidwa ndi liwiro la 800Gbit/s ndi kupitirira apo angakumane ndi mpikisano wogwirizana wa phukusi lolumikizidwa ndi la photoelectric (CPO). Zikuyembekezeka kuti makampani monga Intel, Broadcom, ndi Ranovus apitiliza kusintha mkati mwa chaka chino. Kuwonjezera pa zinthu ndi mayankho a CPO omwe alipo, ndipo akhoza kuyambitsa mitundu yatsopano yazinthu, makampani ena aukadaulo a silicon photonics nawonso adzatsatira kafukufuku ndi chitukuko kapena kulabadira kwambiri.
Kuphatikiza apo, pankhani ya ukadaulo wophatikiza ma photonic kutengera kugwiritsa ntchito ma module optical, ma silicon photonics adzakhala limodzi ndi ukadaulo wophatikiza ma semiconductor a III-V, popeza ukadaulo wa silicon photonics uli ndi kuphatikiza kwakukulu, kuthamanga kwambiri, komanso kugwirizana bwino ndi njira zomwe zilipo za CMOS. Ma photonics a Silicon agwiritsidwa ntchito pang'onopang'ono m'ma module optical apakatikati komanso afupiafupi, ndipo akhala njira yoyamba yofufuzira yophatikizira CPO. Makampaniwa ali ndi chiyembekezo cha chitukuko chamtsogolo cha ukadaulo wa silicon photonics, ndipo kufufuza kwake momwe amagwiritsidwira ntchito mu makompyuta optical ndi madera ena kudzachitikanso mogwirizana.
