I-NEC yaseJapan kunye ne-OCC Corporation encedisayo uphuhliso kunye nokuvavanywa kwezinto eziphindaphindayo ngaphantsi kwamanzi kunye nentambo yokukhanya kunye neeperi ze-20 ze-fibers optical (40 fibers). Eli lirekhodi elitsha lehlabathi.
Impumelelo yangaphambili yayiyeye-NEC - intambo enamaqela ali-16, kwaye kungekudala i-NEC ithembisa ukukhulula abaphindayo kunye neentambo "ezinazibini ezingama-24 okanye ngaphezulu."
I-NEC iphumelele esi siganeko sibalulekileyo ngotshintsho oluncinci kuphela kwisiphindaphindo sayo esiqinisekisiweyo kunye noyilo lwentambo, ushicilelo lweendaba lwatsho. Oku kwenziwa ngokulungiselela amacandelo aphambili aphindaphindayo, kunye nokungqina ukuba uyilo lwentambo esele lukhona lunokwamkela ngokulula imicu emininzi.
Intambo yangaphantsi kwamanzi ye-NEC enemigangatho emininzi yokuqinisa
Abaphinda-phindayo abaphinda-phindayo bepereyitha ezingama-20 bayaqhubeka nokusebenzisa itekhnoloji yokwabelana ngempompo ephindwe kane eyenzelwe yi-NEC ngo-2010 ukubonelela ngokukhanya okuphezulu kunye nokusebenza kakuhle kombane.
Abaphindayo be-NEC abanezandisi zesandisi se-quad zikwiziko le-OCC eKitakyushu (eJapan). Ezi ziphinda-phindwayo zenzelwe indlela kaGoogle engaphantsi kolwandle iFASILE ukunqumla uLwandlekazi lweAtlantiki. Ifoto ethathwe nge-9 kaJulayi, 2015
Ukuveliswa kobuninzi bokuphindaphinda kunye nentambo ye-optical ye-brand entsha sele iqalile.
Kukholelwa ukuba ezona ntambo ziphambili kwitshaneli ze-intercontinental namhlanje zezeGoogle - ezi zitshaneli ze-Equiano kunye ne-Dunant, ezibekwe yinkampani ngoku phakathi konxweme olusempuma lwase-US kunye neFransi, kunye naphakathi kwePortugal noMzantsi Afrika, ngokulandelanayo. Ezi ntambo zineeperi ezili-12 zemicu ye-optical.

I-output ye-12-pair Dunant ichazwe kwi-250 Tbit / s. UGoogle sele ebhengeze intambo enezipere ezingama-24 zefiber optical. Iimodeli zamva nje zekhebula ezivela kuGoogle kunye ne-Subcom zisebenzisa itekhnoloji eshinyeneyo yolwahlulo lwamaza obuninzi, evumela ulwazi ukuba lusasazwe ngaphezulu kwe-100 yamaza ngaphezulu kwefayibha enye.

Ukufakwa kweentambo zangaphantsi kwamanzi yimarike ekhula ngokukhawuleza. Ngokwengxelo , abona benzi bukhulu beentambo zangaphantsi kwamanzi ngoku zezi nkampani zilandelayo:
- I-ASN
- I-TE Subcom
- NEC
- UPrysmian
- Nexans
- Hengtong
- Zhongtian

Iingxilimbela zezonxibelelwano ze-NEC, i-TE Subcom kunye ne-Alcatel-Lucent zisanda kuba phantsi koxinzelelo olukhulayo oluvela kwiinkampani ezinkulu ze-IT ezifana ne-Google, i-Facebook kunye ne-Microsoft, efuna ukuthatha inxaxheba kuzo zombini uphuhliso lweentambo kunye nokubekwa kweendlela zonxibelelwano ezingaphantsi kolwandle.
