Chikwata chevaongorori kubva kuNetwork Research Institute yeNational Institute of Information and Communications Technology (NICT, Japan) yawana rekodhi yenyika itsva yebandwidth mune imwechete.optical fibermwero dhayamita.
Vatsvagiri vakawana bandwidth ingangoita 1.53 petabits pasekondi nekukodha ruzivo pamakumi mashanu neshanu akasiyana mwenje frequencies (nzira inozivikanwa semultiplexing). Izvo zvakakwana bandwidth kutakura ese epasirese traffic yeInternet (inofungidzirwa isingasviki 1 Petabit pasekondi) pane imwechete fiber optic tambo. Ndizvo zviri kure nekubatana kwegigabit kwatinazvo isu vanhuwo zvavo (mumamiriro ezvinhu akanaka): kunyatsojeka; Yakakura nemiriyoni.
Iyo tekinoroji inoshanda nekutora mukana weakasiyana mwenje ma frequency anowanikwa pane ese spectrum. Sezvo imwe neimwe "ruvara" mukati me spectrum (yechiedza chinooneka uye chisingaoneki) ine nguva yaro yakasiyana nedzimwe dzose, inogona kuitwa kutakura yakazvimirira kuyerera kweruzivo. Vatsvakurudzi vakakwanisa kuvhura spectral kunyatsoshanda kwe332 bits/s/Hz (bits pasekondi imwe nguva Hz). Ndiko kupeta katatu kugona kwekuedza kwayo kwekutanga, muna 2019, iyo yakawana spectral kunyatsoshanda kwe105 bits/s/Hz.
