Sehlopha sa bafuputsi ba Network Research Institute of the National Institute of Information and Communications Technology (NICT, Japane) se fihletse rekoto e ncha ea lefatše bakeng sa bandwidth ka nako e le 'ngoe.fiber ea opticalbophara bo tloaelehileng.
Bafuputsi ba fihletse bandwidth ea li-petabits tse ka bang 1.53 motsotsoana ka ho kenya tlhahisoleseling ho maqhubu a fapaneng a 55 a khanya (mokhoa o tsejoang e le multiplexing). Hoo ho lekane ho tsamaisa sephethephethe sa lefats'e sa Marang-rang (e hakanyetsoang ka tlase ho 1 Petabit ka motsotsoana) ka thapo e le 'ngoe ea fiber optic.
