Submarine cable can circle the earth 22 times
Jan 14, 2019

With the rapid rise of streaming media, data traffic has become an integral part of our lives. We can easily view a variety of base stations, fiber optic cables and various communication devices that support everyday communications. However, in terms of global communications, submarine cable is the “central nerve” of the Internet, carrying more than 90% of the world's international voice and data transmission. At present, the total length of the world's submarine cable laying has exceeded 900,000 kilometers, and all of them can be connected 22 times around the earth. filling gel for communication cable


From the perspective of the cable structure, like the land cable, the submarine cable is the core of the middle hairline, but the submarine cable needs stronger armor protection. From the outside to the inside are divided into: polyethylene layer, polyester resin, steel strand layer, aluminum waterproof layer, carbonate resin layer, copper tube, paraffin, alkane layer, and finally to fiber. This dense protective layer is mainly to prevent the cable from being attacked by sea water. Regardless of how it is protected, the cable will still be damaged during wet conditions. The life of submarine cables is generally around 25 years. filling gel for communication cable


Laying submarine cables requires large submarine cables capable of carrying extra long cables. At the same time, underwater robots need to dig trenches and bury cables. The entire laying process is very difficult. In 1850, the United Kingdom established the world's first submarine cable, successfully connecting the United Kingdom and France. In 1988, 130 years later, China laid the first submarine cable. The world's longest submarine cable is 24,000 miles long, extending from Germany to South Korea, then connecting to Singapore and finally to Australia. Today, with the continuous accumulation of technology, China's submarine cable technology has been at the forefront of the world.filling gel for communication cable
