Kua tutuki i tētahi rōpū kairangahau mai i te Network Research Institute o te National Institute of Information and Communications Technology (NICT, Hapani) tētahi rekoata hou o te ao mō te whānui o te hononga i roto i te kotahi... muka whatu o te diameter paerewa.
I tutuki i ngā kairangahau te whānuitanga o te raraunga tata ki te 1.53 petabits ia hekona mā te whakakōrero i ngā mōhiohio puta noa i te 55 ngā auau mārama rerekē (he tikanga e mōhiotia ana ko te multiplexing). He nui te whānuitanga o te raraunga hei kawe i ngā waka ipurangi katoa o te ao (e kiia ana he iti iho i te 1 petabit ia hekona) mā roto i tētahi taura muka whatu kotahi. He rerekē rawa atu tēnei i ngā hononga gigabit e taea ana e te tangata noa te uru atu (i roto i ngā āhuatanga pai rawa atu): kia tika, he miriona ngā wā nui ake.
Ka mahi te hangarau mā te whakamahi i ngā auau rerekē o te mārama e wātea ana puta noa i te whānuitanga. Nā te mea he auau motuhake tō ia "tae" i roto i te whānuitanga (o te mārama e kitea ana, me te mārama e kore e kitea), he rerekē i ngā mea katoa, ka taea te kawe i tana ake rerenga mōhiohio motuhake. I tutuki i ngā kairangahau te pai o te whānuitanga o te 332 bits/s/Hz (bits ia hekona ia Hz). E toru ngā wā he pai ake tēnā i tā rātou ngana pai rawa atu o mua, i te tau 2019, i tutuki ai te pai o te whānuitanga o te 105 bits/s/Hz.
