History

SubCom was founded in 1955 as a company specialising in subsea fibre optic cable systems. It began operations by developing and deploying undersea communication networks, which played a crucial role in global connectivity. The company became known for designing, manufacturing, installing, and maintaining subsea cable networks, supporting international data transmission. Over the years, SubCom expanded its capabilities to provide complete end-to-end solutions for undersea communication infrastructure.

 

As global demand for reliable and high-capacity communication increased, SubCom adapted its technologies to improve data transmission efficiency. It pioneered advancements in repeater technology, which extended the transmission range of optical signals under the ocean. The company played a key role in multiple international cable projects, ensuring secure and fast data transfer across continents.

 

During the 1990s and early 2000s, SubCom was involved in major submarine cable projects that enhanced digital connectivity between regions. The company developed and deployed high-capacity fibre optic networks for commercial, governmental, and scientific purposes. With growing internet usage, SubCom worked on advanced cable systems capable of handling large volumes of data traffic.

 

SubCom continued to innovate and expand its operations, focusing on improving the durability and efficiency of subsea networks. It provided maintenance and repair services through a fleet of specialised cable ships operating in strategic locations worldwide. The company established the Global Technical Support Centre to ensure continuous monitoring and quick response to technical issues.

 

In recent years, SubCom has been involved in multiple large-scale projects, including the deployment of the SEA-ME-WE 6, IEX/IAX, Firmina, IRIS, Grace Hopper, and Oman-Australia cable systems. These networks have significantly improved digital infrastructure by enhancing connectivity between different regions. The company has also contributed to local initiatives, such as installing the first subsea telecom cable in Isle Au Haut to provide broadband access.
