what is submarine optical cable?
Submarine cable is laid on the bottom of the optical fiber cable, it uses the optical signal to transmit information in the optical fiber, with the advantages of fast transmission speed, large capacity, anti-interference, low loss and so on. These cables are usually composed of multiple optical fibers wrapped in a protective layer and insulation material to ensure long-term stability in the deep-sea environment. The emergence of submarine optical cable has greatly promoted the development of global communications, making the international exchange of information more rapid and convenient.
How is the submarine cable laid?
It is a complex and delicate process. First, a special cable ship is used to transport the cable to the designated sea area. During the laying process, the ship uses equipment to lower the cable to the ocean floor as it travels. In deep sea areas, automated equipment such as underwater remote-controlled robots may be used. At the same time, in order to protect the cable from damage, the sea plow will be used to dig out the cable trench on the seabed, and the cable will be buried in it. The entire laying process requires strict control of ship speed to ensure the smooth laying and safety of the cable.
Will the submarine cable be bitten by Marine creatures such as sharks?
Although Marine creatures such as sharks have great strength and keen senses in the ocean, they are not interested in undersea cables. The material and structure of the cable are not attractive to Marine life, and the cable is also wrapped in a thick protective layer and insulation material, enough to resist the attack and erosion of Marine life. Therefore, we do not have to worry about the submarine cable will be damaged by Marine life bite.
How to repair submarine cable?
In the course of long-term use, due to the complexity and uncertainty of the submarine environment, the cable may be affected by various factors and failure or damage. At this time, a professional maintenance team is needed to carry out timely repair. Repairing submarine cables usually requires the help of specialized maintenance ships and robots. The repair team will first pinpoint the fault point, and then use a robot to lift the cable from the seabed and repair it. After the repair is completed, the cable also needs to be rigorously tested and inspected to ensure its quality and safety.
What is the purpose of laying submarine cable?
As an important infrastructure for international communication, submarine optical cable provides a strong support for information exchange on a global scale. It makes the communication between different countries and regions more convenient and efficient, and promotes the prosperity and development of the global economy. At the same time, submarine optical cables also play an important role in financial transactions, scientific research, military communications and other fields. It can be said that submarine cable has become an indispensable part of modern society.
