Tikukamba za zomangamanga zapansi pa madzi zomwe ziyenera kugwira ntchito zaka zitatu zikubwerazi. Izi ndi chingwe cha 2Africa, chozungulira kontinenti ya Africa, transatlantic Dunant ndi JGA North, yomwe idzalumikiza Japan ndi Australia kwa nthawi yoyamba m'zaka 20. Kukambitsirana kuli pansi pa odulidwa.

Chingwe chozungulira Africa
Pakati pa mwezi wa May, makampani angapo a IT ndi ogwira ntchito pa telecom - kuphatikizapo Facebook, Orange, China Mobile ndi Internet Society - za mapulani kuyala chingwe chapansi pamadzi 2 Africa ndi kutalika kwa makilomita 37. Idzalumikiza Europe, Middle East ndi mayiko ena khumi ndi asanu ndi limodzi ku Africa, komwe anthu pafupifupi biliyoni akukumana ndi kusowa kwa intaneti.
Bandwidth 2Africa 180 Tbit / s. Izi ndi mu kuposa zingwe zonse zopita ku Africa pakali pano. Ntchito pakati pa omwe amafananizidwa mu sikelo, pomwe amagwiritsa ntchito kondakitala wa aluminiyamu m'malo mwa mkuwa. Iye kutsika kwamagetsi, komwe kumakupatsani mwayi wowonjezera kuchuluka kwa ma fiber awiri mu chingwe.
Chingwe chatsopanocho chidzamangidwa pogwiritsa ntchito ukadaulo wa Spatial Division Multiplexing (SDM), womwe umapangitsa kuti mawonekedwe aziwoneka bwino. Pankhaniyi, mbali kuwala kwa amplifiers wapakatikati osati ndi ulusi umodzi, koma ndi zingapo nthawi imodzi, zomwe nthawi zina zimawonjezera kutulutsa .
Mtengo weniweni wokhazikitsa pulojekiti ya 2Africa sudziwikabe, koma akatswiri a Bloomberg mtengo wake ndi biliyoni imodzi. Dongosolo la zingwe likukonzekera kuti lizigwira ntchito mu 2023-2024.
Koma izi zisanachitike, zingwe zingapo zapansi pamadzi ziyamba kugwira ntchito.
Ndani winanso akupanga zomangamanga zapansi pa madzi?
Mu 2018 Google za mapulani kuyala chingwe transatlantic makilomita 6,6 zikwi kutalika kulumikiza gombe US ndi France. Dongosololi limatchedwa Dunant. Pano, monga momwe zilili ndi 2Africa, teknoloji ya SDM idzagwiritsidwa ntchito. Idzathandiza kupereka mphamvu ya 250 Tbit / s ndikukulitsa luso la amodzi mwa malo otanganidwa kwambiri. Pa zingwe za Atlantic 55% zambiri kuposa zingwe zaku Pacific.
Dunant ikukonzekera kuti iyambe kugwira ntchito kumapeto kwa chaka chino. M'mwezi wa Marichi, kampani yaku France yamatelefoni ya Orange gawo lake la chingwe ku zida zomangira mdera .

Zikuyamba kugwiritsidwa ntchito sabata ino JGA North System. Kutalika kwake ndi makilomita 2,7, ndipo kutuluka kwake ndi 24 Tbit / s, koma m'chaka chomwe chikubwera chidzawonjezeka kufika 30 Tbit / s. JGA North imalumikiza Japan ndi Guam ndipo imalumikizidwa ndi JGA South, yomwe imayenda pakati pa Guam ndi Sydney. Dongosolo la JGA ili linali chingwe choyamba chapansi pamadzi zaka 20 kulumikiza Japan ndi Australia.
Mu 2021 m'chigawo cha Asia chingwe china cha 128 Tbps chapansi pamadzi ndi SJC2. Idzagwirizanitsa China, Japan, Singapore, South Korea ndi Taiwan. Mtengo wa ntchitoyi ukuyembekezeka kufika $439 miliyoni. Chingwe chowonjezeracho chiyenera kulimbikitsa zowonongeka ndikukhala malo osungiramo zinthu ngati zopuma zosayembekezereka zomwe zikuchitika m'gawoli .
