ʻO wai nā kaula e hoʻopili ai iā ʻApelika, ʻAsia a me Australia?

Ke kamaʻilio nei mākou e pili ana i ka ʻenehana i lalo o ka wai e pono e hana i nā makahiki ʻekolu e hiki mai ana. ʻO kēia nā kaula 2Africa, e hoʻopuni ana i ka ʻāina ʻApelika, ka transatlantic Dunant a me JGA North, e hoʻopili ai iā Iapana a me Australia no ka manawa mua i 20 mau makahiki. Aia ke kūkākūkā ma lalo o ka ʻoki.

Kaula e hoʻopuni ana iā ʻApelika

I ka waena o Mei, he nui nā hui IT a me nā mea lawelawe kelepona - me Facebook, Orange, China Mobile a me Internet Society - kūkala ʻia e pili ana i nā hoʻolālā e kau i kahi kaula submarine 2 ʻApelika me ka lōʻihi o 37 tausani kilomita. E hoʻopili ʻo ia iā ʻEulopa, ka Middle East a me ʻumikumamāono mau ʻāina ʻē aʻe ma ʻApelika, kahi e pili ana i kahi piliona kānaka e kū nei i ka nele o ka pūnaewele.

Bandwidth 2Africa e 180 Tbit/s. Aia kēia i loko ʻehā manawa hou akuma mua o nā kaula āpau e hele ana i ka ʻāina ʻApelika i kēia manawa. Papahana ʻo ia ka mea mua i waena o nā mea like i ka pālākiō, kahi e hoʻohana ai lākou i ka conductor alumini ma kahi o ke keleawe. He hoemi hāʻule ka uila, kahi e hiki ai iā ʻoe ke hoʻonui i ka nui o nā hui fiber i ke kaula.

E kūkulu ʻia ke kaula hou me ka hoʻohana ʻana i ka ʻenehana Spatial Division Multiplexing (SDM), kahi e hoʻonui ai i ka pono spectral. I kēia hihia, nā ʻāpana optical o nā mea hoʻonui waena работают ʻaʻole me hoʻokahi o nā fibers, akā me nā mea he nui i ka manawa hoʻokahi, i kekahi mau mea e hoʻonui i ka throughput ma 70%.

ʻAʻole ʻike ʻia ke kumukūʻai kūpono o ka hoʻokō ʻana i ka papahana 2Africa, akā ʻo nā loea Bloomberg mahalo ʻia he piliona dala kona waiwai. Hoʻolālā ʻia ka ʻōnaehana kelepona e hoʻohana ʻia ma 2023–2024.

Akā ma mua o kēia manawa, e hoʻomaka ana kekahi mau kaula submarine e hana.

ʻO wai nā mea ʻē aʻe e hoʻomohala nei i nā ʻōnaehana ma lalo o ka wai?

I ka makahiki 2018 Google kūkala ʻia e pili ana i nā hoʻolālā e kau i kahi kaula transatlantic 6,6 tausani kilomita ka lōʻihi e pili ana i ke kahakai ʻo US me Farani. Ua kapa ʻia ka ʻōnaehana ʻo Dunant. Maʻaneʻi, e like me keʻano o 2Africa, e hoʻohanaʻia kaʻenehana SDM. E kōkua ia i ka hāʻawi ʻana i kahi mana o 250 Tbit/s a hoʻonui i nā hiki o kekahi o nā wahi ʻoi loa. Ma nā kaula ʻAkelanika lawe aku 55% ʻoi aku ka ʻikepili ma mua o nā uwea Pākīpika.

Hoʻolālā ʻia ʻo Dunant e hoʻohana ʻia i ka hopena o kēia makahiki. I Malaki, ʻo ka hui kelepona ʻo Palani ʻo Orange pili mua ʻO kāna ʻāpana o ke kaula i nā mea hoʻokele ma ke kaiāulu Saint-Hilaire-de-Rieux.

Hoʻohana ʻia i kēia pule hookomoia ʻōnaehana JGA ʻĀkau. ʻO kona lōʻihi he 2,7 tausani mau kilomita, a ʻo kona throughput he 24 Tbit / s, akā i ka makahiki e hiki mai ana e hoʻonui ʻia i 30 Tbit / s. Hoʻopili ʻo JGA ʻĀkau iā Iapana a me Guam a pili iā JGA Hema, e holo ana ma waena o Guam a me Sydney. ʻO kēia ʻōnaehana JGA ka uwea submarine mua loa i nā makahiki 20 e hoʻohui iā Iapana a me Australia.

I ka makahiki 2021 ma ka ʻāina ʻAsia pono e loaa ʻO kekahi 128 Tbps submarine cable ʻo SJC2. E hoʻopili ia iā Kina, Iapana, Singapore, South Korea a me Taiwan. Kuhi ʻia ke kumukūʻai o ka papahana ma $439 miliona. Pono ke kaula hou e hoʻoikaika i ka ʻōnaehana a lilo i wahi mālama i ka wā o nā haʻalulu i manaʻo ʻole ʻia e hiki mai ana ma kēia ʻāpana. mau loa.

He aha kā mākou e kākau ai ma ka blog 1cloud.ru:

ʻO ka lolouila hōʻole e make
He moʻolelo pōkole o Fidonet - he papahana "ʻaʻole mālama" e pili ana i ka lanakila ma ka Pūnaewele
Pehea i ulu ai ka ʻōnaehana inoa inoa: ʻo ka ARPANET Era
Pehea e hoʻokaʻawale ai i ka hoʻokele waiwai IT - e kūkākūkā ana i ʻekolu mau ʻano
