Cov kws tshawb fawb Nyij Pooj los ntawm National Institute of Information and Communications Technology (NICT), Eindhoven University of Technology, thiab Laquila University tau ua tiav qhov kev sib kis tau zoo, ua kom pom lub peev xwm hloov cov ntaub ntawv ntawm tus nqi txog li 22.9 Pb / s los ntawm ib lub cable uas muaj ntau yam fibers optical. Qhov kev ua tiav no tau dhau lub ntiaj teb cov ntaub ntawv dhau los ntawm 10.66 Pb / s, ntau dua ob npaug ntawm qhov ceev.
Qhov kev ua tiav tau ua tiav los ntawm kev sib koom ua ke hauv xeev - ntawm -- cov txuj ci tshawb fawb nrog Space Division Multiplexing (SDM) thiab Wavelength Division Multiplexing (WDM). SDM siv ntau yam -cov tub ntxhais fibers thiab ntau yam kev sib kis technologies los lis ntau tshaj 100 spatial channel, ua ke nrog ntau -bandwidth WDM. Cov kws tshawb fawb tau sib koom ua ke 38-core, peb- hom cable siv ntau- zaus-tshaj MIMO receiver.
NICT tau hais tias qhov no yog thawj zaug sib txawv multiplexing thev naus laus zis tau ua ke, ua rau muaj kev nce qib tseem ceeb hauv kev xa cov ntaub ntawv thev naus laus zis. Cov kev tshawb fawb tshawb pom tau xa thiab lees txais ntawm 49th European Lub Rooj Sab Laj ntawm Kev Sib Txuas Lus Hauv Glasgow. Thaum cov thev naus laus zis tau npaj txhij rau kev koom ua ke rau hauv lub ntiaj teb kho qhov muag kho qhov muag uas twb muaj lawm, kev hloov kho rau cov chaw sib txuas lus tam sim no siv ultra-siab- muaj peev xwm fibers tseem xav tau.
Hauv qhov tseem ceeb, ib zaug xa tawm, cov thev naus laus zis no yuav tsum nce cov ntaub ntawv los ntawm kev muaj peev xwm ntawm cov txheej txheem tshiab los ntawm peb qhov kev txiav txim loj (1000 zaug). Txawm li cas los xij, raws li fiber ntau optic kis ceev cov ntaub ntawv txuas ntxiv tau tawg, nws tseem tsis paub meej tias txoj hauv kev twg yog qhov ua lag luam tshaj plaws.
