First 16 Fiber Pair Repeatered System Ready for Service

HMN Tech announced that the world’s first 16 fiber pair repeatered submarine cable system, Hainan to Hong Kong Express (H2HE) has successfully completed the system commissioning and testing, and is now ready for service.

H2HE connects Hainan Province, Guangdong Province, and Hong Kong SAR with a total length of 675 kilometers. The network facilitates a direct connection between Hainan and Hong Kong, underpinning Hainan as an emerging interconnection hub in the Asia-Pacific region.

The 16 fiber pair network design incorporates HMN Tech’s next generation space-division multiplexing (SDM) technology to achieve a system capacity of over 300Tbps, sufficient to transmit 57,000 high-definition movies every second.

Overcoming a multitude of challenges throughout the entire turnkey delivery process, from design to product manufacturing, system integration to marine installation is critical to bring the concept of a repeatered 16 fiber pair solution to reality. This success further strengthens HMN Tech’s position to achieve greater technological advances in the near future.

“We are delighted to partner with forward-thinking customers such as China Mobile, to successfully deliver the first 16 fiber pair submarine cable system that is a milestone in the industry,” stated Ma Yanfeng, Executive Vice President. “HMN Tech remains committed to developing reliable innovative technology that not only enhances our value proposition but also promotes industry evolution and accelerates the world’s digital transformation.”
