Submarine fiber optic cables are an effective way to interconnect and transmit information internationally. International fiber optic cables play a vital 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 connectivity are imminent. The demand for global interconnection and the interconnection of communications and networks drives the demand for international fiber optic cables. Submarine fiber optic cables have become the primary form of international fiber optic cable due to their high quality, high definition, large capacity, robust security performance, and relatively low cost. According to TeleGeography, over 95% of the world's cross-border data transmission is currently carried out via submarine cables. Submarine fiber optic cables are a technological medium that surpasses satellite communication in transmission capacity and cost-effectiveness, making them the most important transcontinental communication technology today.
The core of a submarine cable is made of high-purity optical fiber, which guides light along the fiber's path through internal reflection. In submarine cable production, the optical fibers are first embedded in a gelatinous compound that protects the cable from damage, even when it comes into contact with seawater. The optical fiber cable is then loaded into a steel tube to prevent breakage from water pressure. Next, it is wrapped in high-strength steel wire, encased in a copper tube, and finally coated with a protective layer of polyethylene material.
