The CABLE connecting World


The Internet Connecting one side of the Atlantic Ocean to the other.




how the Internet is connected all around the world.?

The internet is connected through transatlantic telecommunications cable.It  is a submarine communications cable connecting all around the world underseas.at the very beginning of time these cables are a single wire and after mid-century coaxial cable was use  and then later on optical fiber came into use and now days optical amplifier is widely used.

What are the Submarine communications cable.?

According to Wikkipedia-
A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean. The first submarine communications cables, laid in the 1850s, carried telegraphy traffic. Subsequent generations of cables carried telephone traffic, then data communications traffic. Modern cables use optical fiber technology to carry digital data, which includes telephone, Internet and private data traffic.

Modern cables are typically about 25 millimetres (0.98 in) in diameter and weigh around 1.4 kilograms per metre 
(0.4 lb/ft) for the deep-sea sections which comprise the majority of the run, although larger and heavier cables are 
used for shallow-water sections near shore. [1] [2] As of 2010, submarine cables link all the world's continents 
except Antarctica.

When was the first transatlantic cable laid.?

The first transatlantic telegraph cable was laid in 1858 by businessman Cyrus West Field, it operated for only 
three weeks; subsequent attempts in 1865 and 1866 were more successful.

These submarine cables system offers high speed of up to 2 tbps every single cable.
The submarine transmission is known for having the best security of transmission.
