How do submarine cables work?

How do submarine cables work? underwater submarine optical fiber cable Submarine optical cables are actually optical fibers, which use the propagation characteristics of light in optical fibers to transmit data. However, the submarine optical cable is not a simple optical fiber, it is actually a complex transmission system. The submarine optical cable system consists of two parts: underwater equipment and shore equipment. Underwater equipment It mainly includes optical cable, optical amplifier/repeater and underwater branch unit. What is the repeater used for? As we all know, despite the high speed and sufficient bandwidth of optical fiber, the signal transmission distance is...

Introduce in detail what is a submarine cable

Introduce in detail what is a submarine cable Background The Internet has become an indispensable part of our lives, and the submarine cable is the "central nerve" of the Internet. It carries more than 90% of the world's international voice and data transmission. Without it, the Internet is just a local area network. At present, there are more than 400 submarine optical cables in the world, with a total length of about 1.2 million kilometers, which is three times the distance from the earth to the moon. Only 5% of the international data transmission on the Internet relies on land...

The steps of how the submarine robot repairs the submarine cable

The steps of how the submarine robot repairs the submarine cable The importance of submarine cables The reason why people can communicate and surf the Internet across the mountains and the sea is due to the role of submarine optical cables. Submarine optical cable, also known as submarine communication cable, is a wire wrapped with insulating material and laid on the seabed to establish telecommunication transmission between countries. The submarine optical cable undertakes 90% of the current international communication business in the world and is the main carrier of information communication in the world today. At present, there are about...
