Ua hoʻokō kahi hui o nā mea noiʻi mai ka Network Research Institute o ka National Institute of Information and Communications Technology (NICT, Iapana) i kahi moʻolelo honua hou no ka bandwidth i hoʻokahi ... nā ʻike maka fiber o ke anawaena maʻamau.
Ua hoʻokō nā mea noiʻi i kahi bandwidth o kahi o 1.53 petabits i kekona ma o ke encoding ʻana i ka ʻike ma waena o 55 mau alapine kukui like ʻole (kahi ʻenehana i ʻike ʻia ʻo multiplexing). He lawa kēlā bandwidth e lawe i nā kaʻa pūnaewele āpau o ka honua (manaʻo ʻia ma lalo o 1 petabit i kekona) ma o hoʻokahi kaula fiber optic. He ʻokoʻa loa kēlā mai nā pilina gigabit i hiki i nā kānaka make ke komo (ma nā hiʻohiʻona maikaʻi loa): i ka pololei, he miliona manawa ʻoi aku ka nui.
Hana ka ʻenehana ma ka hoʻohana ʻana i nā alapine like ʻole o ke kukui i loaʻa ma waena o ka spectrum. ʻOiai ʻo kēlā me kēia "kala" i loko o ka spectrum (o ke kukui ʻike ʻia a me ka ʻike ʻole ʻia) he alapine ponoʻī, ʻokoʻa mai nā mea ʻē aʻe a pau, hiki ke hana ʻia e lawe i kāna kahawai ʻike kūʻokoʻa ponoʻī. Ua hoʻokō nā mea noiʻi i ka pono spectral o 332 bits/s/Hz (bits i kekona no Hz). ʻEkolu manawa ʻoi aku ka maikaʻi ma mua o kā lākou hoʻāʻo maikaʻi loa ma mua, i ka makahiki 2019, kahi i hoʻokō ai i ka pono spectral o 105 bits/s/Hz.
Ka manawa hoʻouna: Nov-24-2022
