SEA-H2X

The South-East Asia Hainan-Hongkong Express Cable System (SEA-H2X) is a submarine cable connecting Hong Kong SAR China, Hainan China, the Philippines, Thailand, Malaysia (Borneo Island) and Singapore, with options to extend to Vietnam, Cambodia, the Malaysia Peninsula and Indonesia.

The SEA-H2X consortium comprises China Mobile International Limited (CMI), China Unicom Global (CUG) , Converge Information and Communications Technology Solutions, Inc. (Converge) and PPTEL SEA H2X Sdn. Bhd (PPTEL SEA-H2X). The SEA-H2X Consortium selects HMN Technologies Co., Limited (HMN Tech) to build the system.

Construction and Maintenance Agreement (&MA) and Supply Contract for the SEA-H2X project were effective on March 4, 2022, and come into force as of May 12, 2022.

The SEA-H2X cable system consists of at least 8-fiber pairs between Hong Kong SAR and Singapore, with a design capacity of 160 Tbps to meet the growing bandwidth requirement in the region. Employing an open system model, SEA-H2X has the flexibility to choose best-in-breed Submarine Line Terminal Equipment (SLTE) from third-party vendors at a later date. HMN Tech’s advanced Branching Unit (BU) and Reconfigurable Optical Add/Drop Multiplexer (ROADM) benefits SEA-H2X in providing the ultimate flexibility of electrical power and optical fiber switches across multiple locations.

The SEA-H2X cable system is targeted to be ready-for-service in 2024.

The SEA-H2X will offer diverse connections to the Hainan Free Trade Port, in additional to the Hainan to Hong Kong Express (H2HE) submarine cable system.
