Cov cables twg yuav txuas rau Africa, Asia thiab Australia?

Peb tham txog cov txheej txheem hauv qab dej uas yuav tsum tau ua haujlwm hauv peb lub xyoos tom ntej. Cov no yog 2Africa cable, ncig lub teb chaws African, lub transatlantic Dunant thiab JGA North, uas yuav txuas rau Nyiv thiab Australia thawj zaug hauv 20 xyoo. Kev sib tham nyob hauv qab txiav.

Cable ncig teb chaws Africa

Nyob rau nruab nrab lub Tsib Hlis, ntau lub tuam txhab IT thiab cov neeg siv xov tooj - suav nrog Facebook, Txiv Kab Ntxwv, Tuam Tshoj Txawb thiab Internet Society - tshaj tawm hais txog cov phiaj xwm nteg submarine cable 2 Teb chaws Africa nrog qhov ntev ntawm 37 txhiab kilometers. Nws yuav txuas rau Tebchaws Europe, Middle East thiab kaum rau lwm lub tebchaws hauv tebchaws Africa, qhov twg txog li ib lab tus tib neeg ntsib kev tsis muaj internet.

Bandwidth 2 Teb chaws Africa yuav ua 180 Tbit/s. Qhov no yog nyob rau hauv plaub zaug ntxivtshaj tag nrho cov cables mus rau African sab av loj tam sim no. Qhov project yuav yog thawj ntawm cov piv txwv, qhov twg lawv siv aluminium conductor es tsis txhob tooj liab. Nws txiav hluav taws xob poob, uas tso cai rau koj nce tus naj npawb ntawm fiber ntau khub hauv cable.

Tus tshiab cable yuav tsim siv Spatial Division Multiplexing (SDM) technology, uas optimizes spectral efficiency. Hauv qhov no, cov khoom siv kho qhov muag ntawm qhov nruab nrab amplifiers работают tsis yog nrog ib khub ntawm fibers, tab sis nrog ob peb zaug ib zaug, uas nyob rau qee kis nce throughput rau 70%.

Tus nqi tseeb ntawm kev siv 2Africa qhov project tseem tsis tau paub, tab sis Bloomberg kws tshaj lij txaus siab nws muaj nqis ib txhiab daus las. Lub kaw lus cable tau npaj los ua haujlwm hauv 2023-2024.

Tab sis ua ntej lub sijhawm no, ob peb lub submarine cables yuav pib ua haujlwm.

Leej twg yog leej twg tab tom txhim kho underwater infrastructure?

Hauv 2018 Google tshaj tawm hais txog cov kev npaj yuav nteg ib tug transatlantic cable 6,6 txhiab kilometers ntev txuas US ntug dej hiav txwv nrog Fabkis. Lub kaw lus hu ua Dunant. Ntawm no, ib yam li 2Africa, SDM thev naus laus zis yuav raug siv. Nws yuav pab muab lub peev xwm ntawm 250 Tbit / s thiab nthuav dav lub peev xwm ntawm ib qho chaw uas muaj neeg coob tshaj plaws. Ntawm Atlantic cables xa 55% cov ntaub ntawv ntau dua Pacific cables.

Dunant tau npaj yuav muab tso rau hauv kev ua haujlwm thaum kawg ntawm lub xyoo no. Thaum Lub Peb Hlis, Fabkis kev sib txuas lus lub tuam txhab Orange twb txuas lawm nws ib feem ntawm cov cable rau cov khoom siv davhlau ya nyob twg hauv zej zog Saint-Hilaire-de-Rieux.

Yuav siv tau rau lub lim tiam no qhia JGA North system. Nws qhov ntev yog 2,7 txhiab kilometers, thiab nws cov peev txheej yog 24 Tbit / s, tab sis nyob rau hauv lub xyoo tom ntej nws yuav nce mus rau 30 Tbit / s. JGA North txuas Nyiv thiab Guam thiab txuas nrog JGA South, uas khiav ntawm Guam thiab Sydney. JGA system yog thawj submarine cable hauv 20 xyoo los txuas rau Nyiv thiab Australia.

Xyoo 2021 hauv cheeb tsam Asian yuav tsum khwv tau Lwm 128 Tbps submarine cable yog SJC2. Nws yuav txuas Tuam Tshoj, Nyiv, Singapore, Kaus Lim Qab Teb thiab Taiwan. Tus nqi ntawm qhov project yog kwv yees li ntawm $ 439 lab. Cov kab txuas ntxiv yuav tau ntxiv dag zog rau kev tsim kho vaj tse thiab dhau los ua ib qho chaw cia thaum muaj kev npaj txhij txog tawg uas tshwm sim hauv ntu no tsis tu ncua.
