Iqela labaphandi abavela kwiZiko loPhando lweNethiwekhi yeZiko leSizwe loLwazi kunye neTekhnoloji yoNxibelelwano (i-NICT, eJapan) liphumelele irekhodi elitsha lehlabathi kwi-bandwidth kwelinye.i-fiber opticalIdayamitha esemgangathweni.
Abaphandi baphumelele i-bandwidth malunga ne-1.53 petabits ngesekhondi nge-encoding yolwazi kwii-55 ezahlukeneyo zokukhanya (indlela eyaziwa ngokuba yi-multiplexing). Oko kwanele i-bandwidth yokuthwala zonke i-intanethi ye-intanethi yehlabathi (iqikelelwa ngaphantsi kwe-1 Petabit ngomzuzwana) phezu kwentambo enye ye-fiber optic. Oko kukude kunxibelelwano lwegigabit esinalo thina bantu bafayo (kwiimeko ezingcono kakhulu): ukuchaneka; Inkulu ngokuphindwe ngesigidi.
Itekhnoloji isebenza ngokuthatha ithuba lezandi ezahlukeneyo zokukhanya ezifumanekayo kwi-spectrum. Ekubeni "umbala" ngamnye ngaphakathi kwi-spectrum (yokukhanya okubonakalayo kunye nokungabonakaliyo) ine-frequency yayo eyahlukileyo kuzo zonke ezinye, inokwenziwa ukuba ithwale ukuhamba kwayo okuzimeleyo kolwazi. Abaphandi bakwazile ukuvula ukusebenza kakuhle kwe-spectral ye-332 bits / s / Hz (ii-bits nge-second times Hz). Oku kuphinda-phindwe kathathu ukusebenza kakuhle kwemizamo yayo yangaphambili, ngo-2019, ephumelele ukusebenza kakuhle kwe-105 bits/s/Hz.
