International optical cables are vital to global communications. With the vast majority of international data transmission occurring through submarine optical cables, a country's degree of international optical cable interconnectedness is critical to its economic competitiveness and standard of living. According to a TeleGeography report, over 95% international data is transmitted this way. Since China's first submarine optical cable, which connected with Japan, launched in 1993, submarine optical cables have become the most important way that China connects with the rest of the world.
