What is Submarine Cable?

Submarine Cable is those cables which specially designed to be laid underwater. These types of cables are mainly used for carrying electronic signals, telecommunication, data traffic, Internet data traffic and power.  These cables are the main medium of Internet between all continents in the present world.

Why they Called Submarine Cable?

These cables are called "Submarine" because they usually laid under sea or oceans that is salt water. However, these cables can also be used under normal water bodies like river lakes. This is why they called as Submarine Cable.

Type of Submarine Cable

There are basically two types of Submarine Cable.

1. Submarine Communications Cable
2. Submarine Power Cable

Submarine Communications Cable

Submarine Communication cable is those cables which are used to carry telecommunication signals and laid under water. These cables laid under sea bed which are maintained by land based stations. These cables use optical fiber technology to carry data communication traffic and Internet and private data traffic.

First submarine communications cable was laid in 1850. Then it was used to carry telegraphy traffic. Then after they start transferring transferring telephonic traffic and then data and communication a traffic and now internet data and private data traffic.

Submarine Power Cable

Submarine Power Cables works the same way as Submarine Communication cable that is under water, but it is used to carry power. Some places have water resources in between them and power station. Cable need to travel through water to deliver power to those places. In this situation Submarine cable comes into the picture. Submarine Cables are easily laid under water can safely transfer power.
