I-NEC yaseJapan kanye ne-OCC Corporation engaphansi kwayo ukuthuthukiswa nokuhlolwa kweziphindaphindayo zangaphansi kwamanzi kanye nekhebuli yokubona enamapheya angama-20 emicu yokubona (amafiber angama-40). Leli irekhodi elisha lomhlaba.
Impumelelo yangaphambilini futhi bekungeye-NEC - ikhebula elinamapheya ayi-16, futhi maduze i-NEC ithembisa ukukhulula abaphindayo namakhebuli “ngamapheya angama-24 noma ngaphezulu.”
I-NEC ifinyelele lesi sigameko esiyingqopha-mlando ngezinguquko ezincane kuphela ekwakhiweni kwayo okuphindaphindwayo namakhebula, kusho umbiko wabezindaba. Lokhu kwenziwa ngokuthuthukisa izingxenye eziphindaphindayo ezibalulekile, kanye nokufakazela ukuthi umklamo okhona wekhebula ungamukela kalula imicu eyengeziwe.
Intambo yangaphansi kwamanzi ye-NEC enezendlalelo eziningi zokuqinisa
Abaphindayo bamafayibha angama-20 bayaqhubeka nokusebenzisa ubuchwepheshe bokwabelana ngamaphampu kane owasungulwa yi-NEC ngo-2010 ukuze banikeze ukusebenza kahle okuphezulu kokubona kanye nogesi.
Abaphindayo be-NEC abanama-quad signal amplifiers batholakala embonini ye-OCC e-Kitakyushu (Japan). Lezi ziphindaphinda zenzelwe umzila we-Google ongaphansi kolwandle KAKHULU onqamula uLwandlekazi i-Atlantic. Isithombe sithathwe ngoJulayi 9, 2015
Ukukhiqizwa kwenqwaba yabaphindayo kanye nekhebula le-optical lomkhiqizo omusha seliqalile.
Kukholakala ukuthi izintambo ezithuthuke kakhulu eziteshini ze-intercontinental namuhla ngezika-Google - lezi yiziteshi ze-Equiano ne-Dunant, inkampani okwamanje ebekwe phakathi kogu olusempumalanga ye-US ne-France, kanye naphakathi kwe-Portugal neNingizimu Afrika, ngokulandelana. Lezi zintambo ziqukethe amapheya angu-12 emicu yokubona.

Ukusebenza kwe-Dunant enamapheya ayi-12 kushiwo ku-250 Tbit/s. I-Google isivele imemezele ikhebula elinamapheya angama-24 ama-optical fibers. Amamodeli ekhebula akamuva avela ku-Google kanye ne-Subcom asebenzisa ubuchwepheshe be-multiplexing ye-wavelength eminyene, okuvumela ulwazi ukuthi ludluliselwe kumaza wamaza angaphezu kuka-100 ngefayibha eyodwa.

Ukufakwa kwezintambo ezihamba ngaphansi kwamanzi kuyimakethe ekhula ngokushesha kakhulu. Ngokombiko , abakhiqizi abakhulu bezintambo ezihamba ngaphansi kwamanzi manje sebeyizinkampani ezilandelayo:
- I-ASN
- I-TE Subcom
- I-NEC
- I-Prysmian
- Nexans
- Hengtong
- Zhongtian
Isendlalelo sekhebula lekilasi lokuthembela kusuka ku-Subcom. Isithombe: Subcom
Izikhondlakhondla zezokuxhumana i-NEC, TE Subcom kanye ne-Alcatel-Lucent zisanda kungena ngaphansi kwengcindezi ekhulayo evela ezinkampanini ezinkulu ze-IT ezifana ne-Google, i-Facebook ne-Microsoft, ezifuna ukubamba iqhaza kukho kokubili ukuthuthukiswa kwezintambo kanye nokufakwa kweziteshi zokuxhumana ngaphansi kolwandle.
