The H2 submairne cable system will be the first direct subsea cable between Sydney and Hong Kong (9,200km), with a branch to Los Angeles (12,500km) providing optimal diversity with existing Hawaiki cable.

The H2 cable system will provide the lowest latency from Australia across the Pacific Ocean, with the Sydney to Hong Kong branch carrying 15 Tbps per fibre pair and the Sydney to Los Angeles branch carrying more than 12.9 Tbps per fibre pair, and will follow a diverse route to the north of New Caledonia.

H2 cable seems a sister-cable of Hawaiki Cable. According to Linkedin, H2 Cable Pte. Ltd. is a Singapore-based company.  H2 CEO Georges Krebs still takes the role of Vise President Network and Technology at Hawaiki Cable Limited, while Mr. Rémi Galasso, the Founder and CEO at Hawaiki Cable Limited is the Chairman at H2 Cable.

H2 Cable awarded SubCom the contract to supply, design and install H2 submarine cable system.
