The submarine optical cable is an effective way to realize international interconnection and transmission of information. International optical cables play an important role in international communications. With the rapid development of industries such as cloud computing, big data and the Internet of Things, global data sharing and connection are imminent. The demand for global IDC interconnection and communications and networking interconnection drives the demand for international optical cables. Submarine optical cable has become the main form of international optical cable due to its high quality, high definition, large capacity, good safety performance and high cost. According to TeleGeography, more than 95% of the world's cross-border data transmission is currently carried out via undersea cables. The submarine optical cable is a technological means that surpasses satellite communication in transmission capacity and economy, and is also the most important transcontinental communication technology today.
The core of the submarine cable is made of high-purity optical fiber, which guides light along the fiber path through internal reflection. In the production of submarine cables, optical fibers are first embedded in a gelatinous compound that protects the cable from damage even when it comes into contact with seawater. Then the fiber optic cable is loaded into the steel tube to prevent water pressure from breaking it. Then, it is wrapped in high-strength steel wire, wrapped in copper tube, and finally covered with a protective layer of polyethylene material.
