Dziko la Nokia Bell Labs limalemba zatsopano mu fiber optics kuti zithandizire mwachangu komanso mokweza maukonde a 5G mtsogolo

Posachedwa, Nokia Bell Labs yalengeza kuti ofufuza ake adalemba mbiri yayikulu kwambiri yonyamula imodzi pamakilomita 80, yokhala ndi 1.52 Tbit / s, yomwe ikufanana ndi kutumiza 1.5 miliyoni YouTube makanema nthawi yomweyo. Ndi kanayi ukadaulo wa 400G wapano. Zolemba zapadziko lonse lapansi ndi zina zamaukadaulo opititsa patsogolo zipititsa patsogolo kuthekera kwa Nokia kupanga ma netiweki a 5G kuti akwaniritse zosowa, kuthekera, ndi zosowa za kanthawi kogwiritsa ntchito intaneti ya Zinthu ndi ogula.

Marcus Weldon, Chief Technology Officer wa Nokia komanso Purezidenti wa Nokia Bell Labs, adati: "Chiyambireni kulumikizana ndi ulusi wotsika kwambiri ndi zida zina zowoneka zaka 50 zapitazo. Kuyambira kachitidwe koyambirira ka 45Mbit / s mpaka 1Tbit / s ya masiku ano, Yawonjezeka nthawi zopitilira 20,000 mzaka 40 ndikupanga maziko azomwe timadziwa ngati intaneti komanso gulu ladijito. Udindo wa Nokia Bell Labs nthawi zonse wakhala kutsutsana ndi malire ndikuwonjezeranso malire omwe angakhalepo. Mbiri yathu yaposachedwa kwambiri padziko lonse lapansi pakufufuza kotsimikizika ikutsimikizanso kuti Tikupanga ma network mwachangu komanso mwamphamvu kuti tikhazikitse maziko osinthira mafakitale otsatirawa. "Gulu la Nokia Bell Labs Optical Network Research Group lotsogozedwa ndi Fred Buchali lidapanga gawo limodzi lokhala ndionyamula 1.52Tbit / s. Zolemba izi zimakhazikitsidwa pogwiritsa ntchito mtundu watsopano wa 128Gigasample / wachiwiri wotembenuza womwe umatha kupanga zikwangwani pamtengo wa 128Gbaud, ndipo kuchuluka kwa chidziwitso cha chizindikiro chimodzi kumapitilira ma bits 6.0 / chizindikiro / kugawanika. Izi zidaphwanya mbiri ya 1.3Tbit / s yopangidwa ndi gulu mu Seputembara 2019.

Wofufuza wa Nokia Bell Labs Di Che ndi gulu lake apanganso mbiri yatsopano padziko lonse lapansi ya ma lasers a DML. Ma lasers a DML ndiofunikira pamitengo yotsika mtengo, yothamanga kwambiri monga kulumikizana kwa data center. Gulu la DML lidakwanitsa kupititsa patsogolo ma 400 Gbit / s pa ulalo wamakilomita 15, ndikulemba mbiri yapadziko lonse lapansi.

Labs posachedwapa akwaniritsa zina zazikulu pankhani yolumikizana ndi mawonekedwe.

Ofufuza a Roland Ryf ndi gulu la SDM adamaliza kuyesa koyeserera koyamba pogwiritsa ntchito ukadaulo wama space multiplexing (SDM) pa 4-core yolumikizidwa-pachimake cholumikizira chotalika makilomita 2,000. Kuyesera kumatsimikizira kuti cholumikizira pachimake cha fiber ndichotheka kuthekera ndipo chimakhala ndi magwiridwe antchito ambiri, pomwe chimasunga bizinesiyo mulingo wazitali wa 125um.

Gulu lofufuzira lotsogozedwa ndi Rene-Jean Essiambre, Roland Ryf ndi Murali Kodialam adakhazikitsa mitundu yatsopano yamafayilo omwe atha kupititsa patsogolo magwiridwe antchito amtali komanso osasunthika pamtunda wapamadzi wa 10,000km. Mtundu wotumizira umapangidwa ndi netiweki ya neural ndipo imatha kukhala yabwinoko kuposa mtundu wachikhalidwe (QPSK) womwe umagwiritsidwa ntchito pamakina amasiku ano am'madzi am'madzi.

Wofufuza Junho Cho ndi gulu lake atsimikizira kudzera pakuyesa kuti pakakhala kuchepa kwamagetsi, pogwiritsa ntchito netiweki yolumikizira kuti ikwaniritse fyuluta yopanga phindu kuti ikwaniritse phindu, kuthekera kwa makina am'madzi oyenda pansi pamadzi kungakulitsidwe ndi 23%.

Nokia Bell Labs yadzipereka pakupanga ndikumanga tsogolo la makina olumikizirana ndi makina, kuyendetsa chitukuko cha fizikiki, sayansi ya zinthu, masamu, mapulogalamu, ndi matekinoloje opanga kuti apange ma netiweki atsopano omwe amasintha kusintha kwazinthu, komanso kupitirira malire amakono.
