Submarine cable systems Market Report 2026

The submarine cable systems market size has grown rapidly in recent years. It will grow from $22.19 billion in 2025 to $24.96 billion in 2026 at a compound annual growth rate (CAGR) of 12.5%. The growth in the historic period can be attributed to growth in international telecommunications, rising internet penetration, early expansion of intercontinental cable routes, demand for reliable data connectivity, development of fiber optic technologies.

The submarine cable systems market size is expected to see rapid growth in the next few years. It will grow to $40.14 billion in 2030 at a compound annual growth rate (CAGR) of 12.6%. The growth in the forecast period can be attributed to surge in data center interconnections, rising offshore wind projects, growth in hyperscale cloud providers, increasing need for resilient communication networks, expansion of digital trade. Major trends in the forecast period include expansion of global data transmission capacity, rising deployment of subsea cables for cloud connectivity, growing demand for cross border high bandwidth infrastructure, increased offshore energy integration requiring power cables, advancements in long distance deep sea cable technologies.

The increasing number of telecom and internet subscriptions is playing a crucial role in the growth of the submarine cable system market. Submarine cable systems, which are installed on the seabed, facilitate the transmission of telecommunication signals using optical fiber technology. The rapid expansion of the telecom and internet subscription industries is largely due to the rising utility of smartphones compared to traditional desktop computers. For example, in November 2024, a report by the International Telecommunication Union (ITU), a Switzerland-based specialized UN agency, indicated that 5.5 billion people were online in 2024. This accounts for 68 percent of the global population, up from 65 percent in 2023. The year-on-year growth rate has also risen, from 2.7 percent a year ago to 3.4 percent this year. Consequently, the surge in telecom and internet subscriptions is driving growth in the submarine cable system market.

Leading companies in the Submarine Cable Systems market are concentrating on creating innovative solutions, such as cable systems, to boost global connectivity, expand data transmission capacity, enhance network reliability, and meet the rising demand for high-speed internet and cloud-based services worldwide. Cable systems are interconnected networks of cables designed to transmit electrical power, telecommunications signals, or data between locations. For example, in September 2024, China Mobile Limited, a China-based telecom company, launched the PEACE (Pakistan & East Africa Connecting Europe) subsea cable system, an advanced fiber-optic network linking Asia, Africa, and Europe. The PEACE cable system stretches roughly 21,500 kilometers and features a high-capacity open cable design that supports flexible bandwidth configurations and low-latency routes between Asia and Europe. It strengthens regional connectivity, fosters digital economy growth, and enhances China Mobile’s global infrastructure by enabling faster and more resilient international data transmission.

In October 2023, Citaglobal, a technology and engineering company based in Malaysia, acquired a 30% stake in Ifactors Sdn Bhd for $5.544 million USD. This acquisition aims to enhance Citaglobal's position in the submarine cable systems market and to strengthen its capabilities in the renewable energy and telecommunications sectors. Ifactors Sdn Bhd is a Malaysian company specializing in submarine cable systems.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs on steel armor materials, fiber optic components, and related subsea infrastructure have raised installation and manufacturing costs for submarine cables, most notably affecting communication cable deployments across Asia Pacific and Europe. These tariffs have contributed to project delays and higher capital expenditure for offshore interconnection and power transmission projects. Nevertheless, policies are also encouraging regional manufacturing, innovation in lightweight materials, and diversification of supplier bases, which may help strengthen long term network resilience.
