Ukadaulo wokhazikika wa fiber optic umakwaniritsa kutumiza kwa 1.53 petabit pamphindikati

Gulu la ofufuza ochokera ku Network Research Institute of the National Institute of Information and Communications Technology (NICT, Japan) lapeza mbiri yatsopano yapadziko lonse ya bandwidth mu imodzi.kuwala CHIKWANGWANImuyezo wamba.

Ofufuzawa adapeza bandwidth pafupifupi 1.53 petabits pa sekondi iliyonse polemba zidziwitso pamayendedwe 55 osiyanasiyana (njira yomwe imadziwika kuti multiplexing). Ndiwo bandwidth yokwanira kunyamula kuchuluka kwa anthu pa intaneti padziko lonse lapansi (akuyerekeza osakwana 1 Petabit pa sekondi imodzi) pa chingwe chimodzi cha fiber optic. Izi ndizotalikirana ndi kulumikizana kwa gigabit komwe ife anthu wamba tili nako (muzochitika zabwino kwambiri): kulondola; Ndi kukula kuwirikiza miliyoni.

Tekinolojeyi imagwira ntchito pogwiritsa ntchito mwayi wosiyanasiyana wamagetsi omwe amapezeka pamitundu yonse. Popeza "mtundu" uliwonse mkati mwa sipekitiramu (wa kuwala kowoneka ndi kosaoneka) uli ndi mafupipafupi ake omwe ndi osiyana ndi ena onse, akhoza kupangidwa kuti azinyamula mauthenga ake odziimira okha. Ofufuzawo adatha kutsegulira magwiridwe antchito a 332 bits/s/Hz (bits pa sekondi imodzi Hz). Ndiko kuwirikiza katatu kuchuluka kwa kuyesa kwake kopambana, mu 2019, komwe kunakwaniritsa bwino kwambiri 105 bits/s/Hz.
