In 1988, the world's first intercontinental cable crossed the bottom of the Atlantic Ocean, and the cable, known as TAT-8, was led by three companies, namely AT&T, France Telecom and British Telecom
.
The cable is capable of carrying the equivalent of 40,000 telephone channels, ten times
more than its predecessor, the TAT-7.
In 1989, four new submarine communication cables
began around the world.
(The TAT-8 does not appear in the image above because it was decommissioned
in 2002.
) ）
By the 90s of the 20th century, the number of submarine cables increased
.
By the dawn of the new millennium, every densely populated continent on Earth was connected by fiber optic
cables.
The physical network of the Internet is beginning to take shape
.
As today's video from ESRI, the Environmental Systems Institute, shows that submarine cables have developed rapidly in the early 21st century, reflecting the growth
in global internet usage.
In 2001 alone, eight new submarine cable systems connected North America and Europe
.
From 2016 to 2020 (including plans disclosed), more than 100 new submarine cables were laid around the world, with an estimated total value of $14 billion
.
Now, thanks to undersea cables, even the most remote Polynesian islands can access high-speed internet
.
Even though physical connections are now in almost every corner of the globe, cables are not being built slowly
.
This is due to the increase in capacity of the new cable and our demand for
high-quality video content.
The new cables are so efficient that most of the potential capacity on the main cable route will come from new cables
that are less than five years old.
Traditionally, a consortium of telcos or governments would finance cable construction, but technology companies are increasingly funding
their own submarine cable networks.
Amazon, Microsoft, and Google, for example, have nearly 65 percent market share in cloud data storage, so understandably, they also want to control how data is physically transmitted
.
Currently, the three companies now have 63,605 miles of submarine cable
.
Although laying cables is an expensive job, growing demand
must be met.
Content providers' share of data transfer has skyrocketed from about 8% to nearly 40%
over the past decade.
At the same time, more aging submarine cables will be gradually retired
.
Even if the signal is no longer transmitted over the dark fiber network, it is still used
in production.
Undersea telecommunications cables have proven to be a very effective seismic network, helping researchers study maritime earthquakes and the geological formations
of the seabed.
