Iqela labaphandi abavela kwiNetwork Research Institute yeNational Institute of Information and Communications Technology (NICT, eJapan) bafikelele kwirekhodi entsha yehlabathi yebandwidth kwi-single i-fiber optics yobubanzi obuqhelekileyo.
Abaphandi bafikelele kwi-bandwidth emalunga ne-1.53 petabits ngomzuzwana ngokufaka ulwazi kwiifrequensi zokukhanya ezahlukeneyo ezingama-55 (indlela eyaziwa ngokuba yi-multiplexing). Loo bandwidth yanele ukuthwala yonke ithrafikhi ye-intanethi yehlabathi (eqikelelwa ngaphantsi kwe-1 petabit ngomzuzwana) ngentambo enye ye-fiber optic. Oko kuhluke kakhulu kwiikhonkco ze-gigabit abantu abaqhelekileyo abanokufikelela kuzo (kwiimeko ezilungileyo): ukuba ngokuchanekileyo, ingaphezulu ngokuphindwe ngesigidi.
Le teknoloji isebenza ngokusebenzisa iifrequensi ezahlukeneyo zokukhanya ezikhoyo kwi-spectrum. Ekubeni "umbala" ngamnye ngaphakathi kwi-spectrum (yokukhanya okubonakalayo nokungabonakaliyo) unefrikhwensi yawo, eyahlukileyo kwezinye, unokwenziwa ukuba uthwale umjelo wawo wolwazi ozimeleyo. Abaphandi bafumene ukusebenza kakuhle kwe-spectral kwe-332 bits/s/Hz (bits ngomzuzwana ngeHz). Oko kusebenza ngokuphindwe kathathu kunemizamo yabo yangaphambili, ngo-2019, eyafumana ukusebenza kakuhle kwe-spectral kwe-105 bits/s/Hz.
