The region has evolved into a data centre and cloud services hub, resulting in increased demand for high-capacity underwater cables connecting to other global markets.
China, in particular, has taken the lead in both regional and global underwater cable investments. The country's "Digital Silk Road" policy has resulted in significant spending on underwater cable projects connecting Asia, Africa, Europe, and South America. In 2023, China completed the deployment of a 15,000-kilometer undersea cable system connecting East Asia to Europe, with a design capacity of 180 Tbps and a $600 million investment.
India has also emerged as a major player in the submarine cable business, thanks to its burgeoning digital economy and government initiatives to increase connectivity. The country's underwater cable capacity has expanded by 70% in the previous three years, and it intends to invest in a variety of new technologies to support its digital transformation aspirations. A coalition of Indian telecom providers and global digital corporations has announced a $400 million investment in a new undersea cable system that would connect India to Southeast Asia and the Middle East.
The region has also seen an increase in investment in undersea power lines, particularly those that connect offshore wind farms. Japan and South Korea have led this endeavour since they have a number of large-scale offshore wind projects that require electricity transfer via underwater cables. According to recent predictions, the Asia-Pacific region will account for more than 60% of global offshore wind capacity expansions over the next decade, increasing demand for undersea power cables.
The Submarine Cable Systems market is marked by severe competition between existing firms and newcomers, with a focus on technological innovation, strategic collaborations, and global expansion. Key industry companies are making significant investments in R&D to improve cable capacity, reliability, and efficiency.
Leading rivals in the submarine cable systems market, such as SubCom, Prysmian Group, and NEC Corporation, have established strong positions through their diverse product portfolios and global reach.
