Submarine Cables Market

The Submarine Cables Market is Expected to be Flourished by Rising Demand for High-Speed Internet Connectivity


Submarine cables are laid on the seabed for telecommunication purpose, majorly to provide internet connectivity across borders. These cables carry close to 99% of international communication and data exchange between countries. With rising demand for high-speed internet globally especially for streaming media and video calling, the adoption of 5G networks is surging. Longer and upgraded submarine cables are offering larger bandwidth to support 5G networks and cater to increasing internet traffic. Traditional copper cables are increasingly being replaced by fiber optic cables for higher speeds and capacity.


The global submarine cables market is estimated to be valued at US$ 2751.81 Mn in 2023 and is expected to exhibit a CAGR of 5.1% over the forecast period 2023 to 2030, as highlighted in a new report published by Coherent Market Insights.

Market Dynamics:

The market is driven by rising demand for high-speed internet connectivity worldwide. 5G network rollouts need ultra-high-speed connectivity at peak speeds to support applications such as IoT, industrial automation, self-driving cars etc. which is increasing the need to lay new submarine cables as well as upgrade the existing network infrastructure. Additionally, growing internet traffic stemming from video streaming, social media, file sharing etc. is making internet service providers invest in advanced submarine cables to address bandwidth issues and ensure seamless connectivity globally. However, high capital investment required to lay cables across long sea routes and complex permits associated with international waters continue to hinder the growth of submarine cables market.

Segment Analysis

The submarine cables market is dominated by the communication segment which accounted for over 70% share in 2022. This large share is attributed to the extensive use of submarine cables for telecommunication purposes such as broadband internet, telephone calls and cable television services. The second largest segment is the power cable segment which finds application in infrastructure projects involving offshore wind farms and transmission of hydroelectric power from one landmass to another. This segment is witnessing high growth due to increasing investments in renewable energy sector globally.
