Sithetha ngeziseko ezingundoqo eziphantsi kwamanzi ekufuneka zisebenze kule minyaka mithathu izayo. Ezi ziintambo ze-2Africa, ezirhangqa ilizwekazi laseAfrika, iDunant ewela iAtlantiki kunye neJGA North, eza kudibanisa iJapan ne-Australia okokuqala kwiminyaka engama-20. Ingxoxo iphantsi kokusikwa.

Intambo erhangqa iAfrika
Phakathi kuMeyi, iinkampani ezininzi ze-IT kunye nabaqhubi be-telecom - kuquka i-Facebook, i-Orange, i-China Mobile kunye ne-Internet Society - malunga nezicwangciso zokubeka intambo yangaphantsi kwamanzi 2Afrika ubude beekhilomitha ezingamawaka angama-37. Iza kudibanisa iYurophu, uMbindi Mpuma kunye namanye amazwe alishumi elinesithandathu e-Afrika, apho abantu abamalunga nebhiliyoni bajongene nokunqongophala kwe-intanethi.
I-Bandwidth 2Afrika 180 Tbit/s. Oku kungaphakathi ngaphezu kwazo zonke iintambo eziya kwilizwekazi laseAfrika okwangoku. Iprojekthi phakathi kwezo zithelekiseka kwisikali, apho zisebenzisa umqhubi we-aluminium endaweni yobhedu. Yena i-voltage yehla, ekuvumela ukuba ukwandise inani leeperi zefayibha kwintambo.
Intambo entsha iya kwakhiwa kusetyenziswa ubuchwepheshe be-Spatial Division Multiplexing (SDM), eyenza ukusebenza kakuhle kwe-spectral. Kule meko, amacandelo optical of the intermediate amplifiers hayi ngeperi enye yeentsinga, kodwa nezininzi ngaxeshanye, ethi kwezinye iimeko inyuse i-throughput .
Iindleko kanye zokuphumeza iprojekthi ye-2Africa azikaziwa, kodwa iingcali zaseBloomberg ixabisa ibhiliyoni yeedola. Inkqubo yentambo icwangciswe ukuba isetyenziswe kwi-2023-2024.
Kodwa ngaphambi kwalo mzuzu, iintambo ezininzi ezingaphantsi kwamanzi ziya kuqalisa ukusebenza.
Ngubani omnye ophuhlisa iziseko ezingundoqo zangaphantsi kwamanzi?
Ngo-2018 Google malunga nezicwangciso zokubeka intambo ye-transatlantic i-6,6 yeekhilomitha eziliwaka elide ezidibanisa unxweme lwase-US neFransi. Inkqubo yayibizwa ngokuba yiDunant. Apha, njengakwimeko ye-2Africa, iteknoloji yeSDM iya kusetyenziswa. Kuya kunceda ukubonelela ngesakhono se-250 Tbit / s kunye nokwandisa amandla kwenye yezona ndawo zixakekileyo. Kwiintambo zeAtlantiki I-55% idatha ngaphezu kweentambo ze-Pacific.
I-Dunant icwangciselwe ukuba iqalise ukusebenza ekupheleni kwalo nyaka. NgoMatshi, inkampani yezonxibelelwano yaseFransi iOrange inxalenye yayo yentambo kwisixhobo setheminali kuluntu .

Iya kusetyenziswa kule veki Inkqubo yaseMantla yeJGA. Ubude bayo buyi-2,7 yeekhilomitha eziliwaka, kwaye ukuphuma kwayo ku-24 Tbit / s, kodwa kunyaka ozayo kuya kwandiswa ukuya kwi-30 Tbit / s. I-JGA North idibanisa iJapan kunye neGuam kwaye iqhagamshelwe kwi-JGA yaseMzantsi, ehamba phakathi kweGuam neSydney. Le nkqubo ye-JGA yayiyintambo yokuqala yangaphantsi kwamanzi kwiminyaka engama-20 ukudibanisa iJapan ne-Australia.
Ngo-2021 kummandla waseAsia enye 128 Tbps inkwili intambo yi SJC2. Iza kudibanisa iChina, iJapan, iSingapore, iSouth Korea neTaiwan. Iindleko zale projekthi ziqikelelwa kwi-439 yezigidi zeerandi. Intambo eyongezelelweyo kuya kufuneka yomeleze iziseko zophuhliso kwaye ibe yindawo yogcino xa kukho ukuqhawuka okungalindelekanga okwenzeka kweli candelo .
