According to a research report by CITIC Securities, undersea cables are laid at a depth of 8,000 meters to connect data centers in different regions around the world for high-speed information transmission, with high industry barriers. Driven by AI, internet giants are increasing their investments in undersea cable construction; domestic deep-sea technology is included in the government work report, and the demand for undersea cables is also expected to rise due to ocean observation. It is estimated that from 2026 to 2030, the length of newly constructed undersea cables globally will be about 540,000 kilometers, a 60% increase compared to the planned construction length from 2021 to 2025. The CAGR of the undersea cable market is expected to be 13% from 2025 to 2030. It is anticipated that China will dominate more undersea cable projects in the future, with the competitiveness of domestic undersea cable companies continuing to strengthen, and there is optimism about leader companies.
