The South East Asia Hainan – Hong Kong Express Cable System (SEA-H2X), a new, high-performance, submarine cable connecting the Philippines, Hong Kong, SAR China, Hainan China, Thailand, East Malaysia and Singapore, will bring the speed and capacity to digitally transform the region in two years.

Converge Information and Communications Technology Solutions, Inc. (Converge), China Mobile International Limited (CMI), China Unicom Global (CUG) and PPTEL SEA H2X Sdn. Bhd (PPTEL SEA-H2X), reaffirmed their partnership Thursday, May 12, to construct and operate the SEA-H2X.

The proponents also have options to extend the submarine cable system to Vietnam, Cambodia, West Malaysia and Indonesia.


The SEA-H2X cable spans approximately 5,000 kilometers and consists of at least 8-fiber pairs between Hong Kong SAR and Singapore.

It has a design capacity of 160 terabits per second and will be ready-for-service in 2024.

The parties to the SEA-H2X Project have appointed HMN Technologies Co., Limited (HMN Tech) to design, build and deploy the cable system.

The Construction and Maintenance Agreement (C&MA) as well as the Supply Contract with HMN Tech took effect March 4, 2022.

The cable will cater to the high broadband (Internet) demand between Hong Kong SAR and Southeast Asian countries, providing capacity and faster transmission, aside from laying the groundwork for the 5G era.

“We are pleased to be a partner in this trans-Asia cable that will respond to the booming data traffic between Hong Kong SAR and Southeast Asia,” stated Converge CEO and Co-Founder Dennis Anthony Uy.

“This submarine cable system will boost the connectivity between our two PoPs located in Hong Kong and in Singapore,” he noted.

In addition, “This will serve as a crucial infrastructure to add diversity and redundancy to our international network.”

“We are truly diversifying our international capacity portfolio as trans-Pacific demand will be served by the Bifrost, and now trans-Asia demand will be served by SEA-H2X,” Uy concluded.
