The increasing demand for inter-country and island connections is propelling the growth of the undersea cabling market. Enhanced international connectivity has resulted in some of the highest fixed broadband penetration rates in the region, with many consumers utilizing FTTP-based services. For example, in January 2024, the Washington State Department of Transportation, a US-based government agency, reported that Washington State Ferries experienced an increase of over 1.3 million riders in 2023 compared to 2022. This led to a 7.4% rise in annual ridership, reaching nearly 18.7 million. This surge signifies a notable rebound in ferry usage year-over-year. Consequently, the growing demand for inter-country and island connections is anticipated to drive the undersea cabling market throughout the forecast period.

The rising number of data centers is anticipated to boost the growth of the undersea cabling market in the coming years. Data centers are facilities that contain computer systems, servers, and networking equipment responsible for storing, processing, and managing large volumes of digital information to support various online services and applications. Undersea cabling plays a crucial role in data centers by enabling high-speed and reliable data transmission over long distances, thereby connecting servers and enhancing global internet connectivity. For example, in January 2024, Newmark Group Inc., a US-based commercial real estate advisor and service provider, projected that the demand for data centers in the U.S. would grow significantly, reaching 35 GW by 2030, up from just 17 GW in 2022. Thus, the increasing number of data centers is expected to drive the undersea cabling market throughout the forecast period.

The evolution toward faster connectivity with 5G in undersea cabling solutions is shaping the undersea cabling market. Notably, in February 2022, global telecommunication companies Bharati Airtel and Reliance Jio invested in improving submarine cable systems' capacity to develop low-latency 5G networks expected to roll out in the next fiscal year. Bharti Airtel's participation in the SEA-ME-WE-6 undersea cable consortium aims to enhance its network's high-speed capacity, contributing to the growth of India's digital economy. Simultaneously, Reliance Jio's cable system, IAX network, facilitates direct connections between the Maldives, India, and Singapore.

Major companies in the undersea cabling market are strategically focusing on expanding existing commercial projects to gain a competitive edge. The expansion of these projects is anticipated to enhance global connectivity and support the increasing demands for data. For example, in October 2023, Google LLC entered into an agreement with the United States and Australian governments to operate undersea cables, extending internet access to a minimum of eight Pacific Ocean countries. This agreement represents an expansion of Google's existing commercial project in the region, providing connectivity to Micronesia, Kiribati, the Marshall Islands, Papua New Guinea, the Solomon Islands, Timor-Leste, Tuvalu, and Vanuatu.
