Loaʻa ka ʻenehana fiber optic maʻamau i ka hoʻouna ʻana i ka moʻolelo o 1.53 petabit i kekona

Ua loaʻa i 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.puluniu makaanawaena maʻamau.

Ua loaʻa i nā mea noiʻi kahi bandwidth o kahi 1.53 petabits i kēlā me kēia kekona ma ka hoʻopili ʻana i ka ʻike ma 55 mau alapine māmā like ʻole (kahi ʻenehana i ʻike ʻia he multiplexing). Ua lawa ia ka bandwidth e lawe i nā kaʻa pūnaewele puni honua (manaʻo ʻia ma lalo o 1 Petabit i kekona) ma luna o kahi uwea fiber optic hoʻokahi. He mamao loa ia mai nā pili gigabit i loaʻa iā mākou nā kānaka make wale nō (i nā hiʻohiʻona maikaʻi loa): e pololei; He miliona ka nui.

Ke hana nei ka ʻenehana ma o ka hoʻohana ʻana i nā alapine māmā like ʻole i loaʻa ma ka spectrum. No ka mea, ʻo kēlā me kēia "kala" i loko o ka spectrum (ʻike ʻia a ʻike ʻole ʻia) kona alapine ponoʻī i ʻokoʻa mai nā mea ʻē aʻe a pau, hiki ke hana ʻia e lawe i kāna kahe kūʻokoʻa o ka ʻike. Ua hiki i nā mea noiʻi ke wehe i ka pono spectral o 332 bits/s/Hz (bits per second times Hz). ʻO ia ʻekolu mau manawa o ka maikaʻi o kāna hoʻāʻo maikaʻi loa ma mua, i ka makahiki 2019, ka mea i loaʻa i ka pono spectral o 105 bits/s/Hz.
