Nokia Bell Labs yapadziko lonse lapansi imalemba zatsopano mu fiber optics kuti zitheke ma network a 5G amtsogolo mwachangu komanso apamwamba.

Posachedwa, Nokia Bell Labs idalengeza kuti ofufuza ake adakhazikitsa mbiri yapadziko lonse lapansi yokhala ndi chonyamulira chapamwamba kwambiri pamtundu umodzi wamtunda wamakilomita 80, wokhala ndi 1.52 Tbit/s, womwe ndi wofanana ndi kutumiza YouTube 1.5 miliyoni. mavidiyo nthawi yomweyo.Ndi kuwirikiza kanayi luso lamakono la 400G.Mbiri yapadziko lonse lapansi iyi komanso zida zina zapaintaneti zowoneka bwino zipititsa patsogolo luso la Nokia lopanga ma netiweki a 5G kuti akwaniritse zosowa zapaintaneti yazinthu zamafakitale komanso kugwiritsa ntchito ogula.

A Marcus Weldon, Chief Technology Officer wa Nokia komanso Purezidenti wa Nokia Bell Labs, adati: "Kuyambira kupangidwa kwa ulusi wapang'ono wotayika komanso zida zofananira nazo zaka 50 zapitazo.Kuchokera pamakina oyambilira a 45Mbit/s mpaka dongosolo lamakono la 1Tbit/s, Lakula nthawi zopitilira 20,000 mzaka 40 ndikupanga maziko azomwe timadziwa ngati intaneti komanso gulu la digito.Ntchito ya Nokia Bell Labs nthawi zonse yakhala ikutsutsa malire ndikutanthauziranso malire omwe angathe.Mbiri yathu yaposachedwa kwambiri padziko lonse lapansi pa kafukufuku wamawonekedwe akutsimikiziranso kuti Tikupanga maukonde othamanga komanso amphamvu kwambiri kuti tikhazikitse maziko akusintha kwamakampani kukubwera. ”Nokia Bell Labs Optical Network Research Group motsogozedwa ndi Fred Buchali idapanga chonyamulira chimodzi mpaka 1.52Tbit/s.Zolemba izi zimakhazikitsidwa pogwiritsa ntchito chosinthira chatsopano cha 128Gigasample / chachiwiri chomwe chingathe kupanga zizindikiro pamtunda wa chizindikiro cha 128Gbaud, ndipo chiwerengero cha chidziwitso cha chizindikiro chimodzi chimaposa 6.0 bits / chizindikiro / polarization.Izi zidaphwanya mbiri ya 1.3Tbit/s yomwe gululi linapanga mu Seputembala 2019.

Wofufuza wa Nokia Bell Labs Di Che ndi gulu lake akhazikitsanso mbiri yatsopano yapadziko lonse lapansi yama lasers a DML.Ma lasers a DML ndi ofunikira pakugwiritsa ntchito zotsika mtengo, zothamanga kwambiri monga kulumikizana pakati pa data.Gulu la DML lidapeza kuchuluka kwa ma data kupitilira 400 Gbit/s pa ulalo wa 15-km, ndikuyika mbiri padziko lonse lapansi. Kuphatikiza apo, ofufuza a Nokia Bell

Ma Labs posachedwapa apanga zopambana zina zazikulu pankhani ya kulumikizana kwa kuwala.

Ofufuza a Roland Ryf ndi gulu la SDM adamaliza kuyesa koyamba pogwiritsa ntchito ukadaulo wa space division multiplexing (SDM) pa 4-core coupled-core fiber yomwe imayenda makilomita 2,000.Kuyeseraku kumatsimikizira kuti nsonga yolumikizirana ndiyotheka mwaukadaulo ndipo imakhala ndi ntchito yotumizira kwambiri, ndikusunga mainchesi a 125um cladding.

Gulu lofufuza motsogozedwa ndi Rene-Jean Essiambre, Roland Ryf ndi Murali Kodialam linayambitsa njira zatsopano zosinthira zomwe zingapereke magwiridwe antchito abwino kwambiri otumizirana ma Linea komanso osatsata mzere pamtunda wa 10,000km.Mawonekedwe opatsirana amapangidwa ndi neural network ndipo amatha kukhala abwino kwambiri kuposa mawonekedwe achikhalidwe (QPSK) omwe amagwiritsidwa ntchito pamakina amakono apamadzi apamadzi.

Katswiri wofufuza Junho Cho ndi gulu lake atsimikizira kudzera mu zoyesera kuti pakakhala mphamvu zochepa, pogwiritsa ntchito neural network kuti akwaniritse zosefera kuti akwaniritse kuchuluka kwa mphamvu, mphamvu ya chingwe chapansi pamadzi imatha kuonjezedwa ndi 23%.

Nokia Bell Labs idadzipereka kupanga ndi kumanga tsogolo la machitidwe olumikizirana owoneka bwino, ndikuyendetsa chitukuko cha sayansi, masamu, masamu, mapulogalamu, ndi matekinoloje owoneka bwino kuti apange maukonde atsopano omwe amagwirizana ndi kusintha kwa zinthu, komanso kupitilira malire amasiku ano.
