Gulu la ofufuza ochokera ku Network Research Institute of the National Institute of Information and Communications Technology (NICT, Japan) lapeza mbiri yatsopano padziko lonse ya bandwidth mu imodzi. kuwala kwa fiber ya mulifupi wokhazikika.
Ofufuzawa adapeza bandwidth ya pafupifupi 1.53 petabits pa sekondi imodzi polemba zambiri kudzera m'ma frequency 55 osiyanasiyana a kuwala (njira yotchedwa multiplexing). bandwidth imeneyo ndi yokwanira kunyamula anthu onse pa intaneti padziko lonse lapansi (omwe akuyerekeza kuti ndi ochepera 1 petabit pa sekondi imodzi) kudzera mu chingwe chimodzi cha fiber optic. Izi ndi zosiyana kwambiri ndi maulumikizidwe a gigabit omwe anthu wamba amatha kupeza (muzochitika zabwino kwambiri): kunena zoona, ndi yayikulu kuwirikiza miliyoni.
Ukadaulowu umagwira ntchito pogwiritsa ntchito ma frequency osiyanasiyana a kuwala omwe amapezeka pa sipekitiramu iliyonse. Popeza "mtundu" uliwonse mkati mwa sipekitiramu (ya kuwala kooneka ndi kosaoneka) uli ndi ma frequency akeake, mosiyana ndi ena onse, ukhoza kupangidwa kuti ukhale ndi mtsinje wake wodziyimira pawokha wa chidziwitso. Ofufuzawo adapeza mphamvu ya spectral ya 332 bits/s/Hz (bits pa sekondi iliyonse pa Hz). Izi ndi zogwira mtima katatu kuposa momwe adayesera kale, mu 2019, zomwe zidapeza mphamvu ya spectral ya 105 bits/s/Hz.
