Tinotaura pamusoro pezvivakwa zvepasi pemvura izvo zvinofanirwa kunge zvichishanda mumakore matatu anotevera. Idzi ndidzo tambo dze2Africa, dzakatenderedza kondinendi yeAfrica, iyo transatlantic Dunant neJGA North, iyo ichabatanidza Japan neAustralia kekutanga mumakore makumi maviri. Hurukuro iri pasi pekucheka.

Cable yakatenderedza Africa
Pakati paChivabvu, akati wandei makambani eIT uye telecom vanoshanda - kusanganisira Facebook, Orange, China Mobile uye Internet Society - nezvezvirongwa zvekuisa tambo yepasi pemvura 2Africa nehurefu hwemakiromita 37 zviuru. Ichabatanidza Europe, Middle East nedzimwe nyika gumi nenhanhatu muAfrica, uko vanhu vangangosvika bhiriyoni vakatarisana nekushaikwa kweinternet.
Bandwidth 2Africa 180 Tbit/s. Izvi zviri mukati kupfuura tambo dzose dzinoenda kuAfrica kondinendi panguva ino. Project pakati peiyo inofananidzwa muchiyero, kwavanoshandisa aluminium conductor pachinzvimbo chemhangura. Iye voltage inodonha, iyo inokubvumira kuti uwedzere nhamba yefiber pairi mutambo.
Iyo tambo nyowani ichavakwa uchishandisa Spatial Division Multiplexing (SDM) tekinoroji, iyo inogonesa spectral kunyatsoita. Muchiitiko ichi, optical components of the intermediate amplifiers kwete nefiber imwe chete, asi neakawanda kamwechete, iyo mune dzimwe nguva inowedzera kubuda .
Mutengo chaiwo wekuita chirongwa che2Africa hausati wazivikanwa, asi nyanzvi dzeBloomberg mutengo wayo bhiriyoni remadhora. Iyo cable system yakarongwa kuiswa mukushanda muna 2023-2024.
Asi nguva ino isati yasvika, mamwe tambo dzepasi pemvura dzinoverengeka dzichatanga kushanda.
Ndiani mumwe ari kugadzira zvivakwa zvepasi pemvura?
Muna 2018 Google nezve hurongwa hwekuisa tambo ye transatlantic makiromita 6,6 zviuru kureba ichibatanidza mahombekombe eUS neFrance. Hurongwa uhu hwainzi Dunant. Pano, sezvakaita 2Africa, teknolojia yeSDM ichashandiswa. Ichabatsira kupa huwandu hwe250 Tbit / s uye kuwedzera kugona kweimwe yenzvimbo dzakabatikana. PaAtlantic cables 55% yakawanda data kupfuura Pacific tambo.
Dunant yakarongwa kuti itange kushanda mukupera kwegore rino. Muna Kurume, kambani yekuFrance yekufonera Orange chikamu chayo chetambo kune terminal midziyo munharaunda .

Iri kushandiswa svondo rino JGA North system. Kureba kwayo ndeye 2,7 zviuru zvemakiromita, uye kubuda kwayo ndeye 24 Tbit / s, asi mugore rinouya ichawedzerwa kusvika 30 Tbit / s. JGA North inobatanidza Japan neGuam uye yakabatana neJGA Maodzanyemba, inomhanya pakati peGuam neSydney. Iyi JGA system yaive yekutanga tambo yepasi pemvura mumakore makumi maviri yekubatanidza Japan neAustralia.
Muna 2021 munharaunda yeAsia imwe 128 Tbps tambo yepasi pemvura iSJC2. Ichabatanidza China, Japan, Singapore, South Korea neTaiwan. Mari yechirongwa ichi inofungidzirwa kuti inosvika mamiriyoni mazana mana nemakumi matatu nemapfumbamwe emadhora. Iyo yekuwedzera tambo ichafanirwa kusimbisa zvivakwa uye kuve nzvimbo yekuchengetera kana paine kuputika kusingatarisirwe kunoitika muchikamu chino .
