9,000km internet cable laid under Pacific Ocean

  • 4th July 2016

Google, alongside 5 other companies, have laid a 9,000km cable under the Pacific Ocean from the USA to Japan, and have now activated it.

Working in partnership, Google, China Telecom Global, China Mobile International, SingTel,, Global Transit and KDDI were all involved in creating and laying the “Faster” cable, with the systems being supplied by the NEC Corporation. The project cost £222m.

Urs Hölzle, Google’s senior vice president of technical infrastructure, says the “Faster” cable is “the first of its kind, with multiple colours (100) of light transmitted over various frequencies” and is “10 million times faster than your cable modem”.

“Every ~60km a repeater re-energizes the light as it travels over 9,000km across the ocean floor”, Hölzle added.

Though this cable is the first of its kind, undersea cables are not new. The first cable laid was across the Atlantic, was used to facilitate telegrams and was laid 110 years ago, in 1906.

Facebook and Microsoft announced they will be building a new undersea cable under the Atlantic, connecting Virginia, US to Europe at Bilbao, Spain.
