Sehlopha sa bafuputsi ba tsoang Setsing sa Lipatlisiso sa Network Institute of the National Institute of Information and Communications Technology (NICT, Japane) se fihletse rekoto e ncha ea lefats'e bakeng sa bandwidth ka e le 'ngoe. li-fiber optics ea bophara bo tloaelehileng.
Bafuputsi ba fihletse bandwidth ea hoo e ka bang li-petabit tse 1.53 ka motsotsoana ka ho kenya tlhahisoleseling maqhubung a fapaneng a leseli a 55 (mokhoa o tsejoang e le multiplexing). bandwidth eo e lekane ho jara sephethephethe sohle sa inthanete lefatšeng (se hakanyetsoang ho petabit e le 'ngoe ka motsotsoana) ka thapo e le 'ngoe ea fiber optic. Seo se fapane haholo le likhokahano tsa gigabit tseo batho ba shoang feela ba nang le phihlello ho tsona (maemong a matle ka ho fetisisa): ho nepahala, e kholo ka makhetlo a milione.
Theknoloji ena e sebetsa ka ho sebelisa maqhubu a fapaneng a leseli a fumanehang ho pholletsa le spectrum. Kaha "'mala" o mong le o mong ka har'a spectrum (ea leseli le bonahalang le le sa bonahaleng) o na le maqhubu a oona, a fapaneng le a mang kaofela, o ka etsoa hore o jare phallo ea oona ea tlhahisoleseling e ikemetseng. Bafuputsi ba fihletse katleho ea spectral ea 332 bits/s/Hz (li-bits ka motsotsoana ka Hz). Seo se sebetsa hantle ka makhetlo a mararo ho feta boiteko ba bona bo botle ba pele, ka 2019, bo fihletseng katleho ea spectral ea 105 bits/s/Hz.
