Industry 4.0 – Google Optic Fiber Cable

Industry 4.0 – Google Optic Fiber Cable


Globally there are 378 undersea optic fiber cables connecting various continents. In 2019 Google has installed its dedicated cable from the USA to Europe which is the highest-capacity cable in the world.


The cable has 24 strands & is named “Dunant” ~ it is named after the founder of the Red Cross – Henry Dunant. The cable length is 6,000 km. It’s a private Google cable & is a part of Google’s network carrying internal data & synchronizing Gmail, YouTube, cloud data & other services in real-time between all Google data centers in the USA & Europe. We can download 250 terabits per second speed 1 terabyte HDD data in 30 milliseconds.

Google has planned to lay more than 3,000 miles of the transatlantic undersea cable by 2022. The tech gigantic has declared its new Grace Hopper undersea cable project. The Grace Hopper cable would connect New York to Bude in the UK and Bilbao, Spain. The distance is unevenly 3,290 miles from New York to Bude in Cornwall, England. The Grace Hopper marks its first private investment in a private subsea cable route to the UK. That was its first-ever cable route to Spain. The Grace Hopper cable is expected to be completed by 202. The company would use a new method to make it more dependable than current fiber-optic cables.

Reliability in global communications

The Grace Hopper will join novel optical fiber switching that lets for increased reliability in global communications. That will enable us to healthier move traffic around outages. According to Google, the cable is set to funnel 340-350 terabytes of data per second that equates to 17.5 million people streaming 4K videos instantaneously. Google has already three privately-owned undersea cables:

  • Curie, Dunant, and Equiano. Google said. The Curie turns down the West coast of the US from Los Angeles all the way down to Valparaiso in Chile, stopping off in Panama, and is already online.
  • Dunant stretches from Virginia Beach in the US to France and is likely to become accessible later this year.
  • Equiano innings from Portugal all the way down the West coast of Africa to Cape Town, South Africa, and is expected to be completed next year.

Equiano is no different as Google’s private subsea cables all carry the names of historical luminaries. The Equiano cable is a state-of-the-art infrastructure based on space-division multiplexing (SDM) technology. It is about 20 times more network capacity than the last cable built to serve this region.

Somewhat the outdated approach of wavelength-level switching the Equiano would be the first subsea cable to incorporate optical switching at the fiber-pair level. This importantly abridges the allocation of cable capacity that gives us the flexibility to add and move it in different locations as wanted. We’re able to accelerate our construction timeline and optimize the number of negotiating parties as Equiano is fully funded by Google.

About project

Google Fiber is a project that’s goal is to shape a fiber-optic communications infrastructure. Google Fiber connections would come into metropolitan areas over multiple aggregators. Fiber optic cables will branch out and run into neighborhoods and individual residences. These will provide FTTH (fiber to the home) service from these points. Abundant of the cable shall be threaded on new and present utility poles as some of it would be hidden. The system is likely to provide Internet connection speeds of up to 1 Gbps to end-users.
