Ithimba labacwaningi abavela ku-Network Research Institute ye-National Institute of Information and Communications Technology (NICT, Japan) lizuze irekhodi elisha lomhlaba lomkhawulokudonsa ngesikhathi esisodwa.i-fiber opticalububanzi obujwayelekile.
Abacwaningi bathole umkhawulokudonsa olinganiselwa ku-1.53 petabits ngomzuzwana ngokufaka ulwazi kumafrikhwensi okukhanya ahlukene angama-55 (inqubo eyaziwa ngokuthi i-multiplexing). Lowo mkhawulokudonsa owanele ukuthwala yonke ithrafikhi ye-inthanethi yomhlaba (ilinganiselwa ngaphansi kwe-Petabit eyi-1 ngesekhondi) ngentambo eyodwa ye-fiber optic. Lokho kukude kakhulu nokuxhumana kwe-gigabit thina bantu abafayo esinakho esinakho (ezimweni ezinhle kakhulu): ukunemba; Inkulu ngokuphindwe ngesigidi.
Ubuchwepheshe busebenza ngokusebenzisa amaza okukhanya ahlukene atholakala ku-spectrum. Njengoba "umbala" ngamunye ngaphakathi kwe-spectrum (wokukhanya okubonakalayo nokungabonakali) unemvamisa yawo ehlukile kuzo zonke ezinye, ungenziwa ukuthi uphathe ukuhamba kwawo okuzimele kolwazi. Abacwaningi bakwazile ukuvula ukusebenza kahle kwe-spectral kwe-332 bits/s/Hz (amabhithi ngesekhondi ngalinye Hz). Lokho kuphindwe kathathu ukusebenza kahle komzamo wayo wangaphambilini ongcono kakhulu, ngo-2019, ozuze ukusebenza kahle kwe-spectral kwe-105 bits/s/Hz.
