Hong Kong, 9 July, 2018 The Bay to Bay Express Cable System (BtoBE) consortium, composed of China Mobile International (CMI), Facebook and Amazon Web Services (AWS), signed an agreement with NEC Corporation (NEC; TSE:6701) to build a high performance submarine cable connecting Singapore, Hong Kong and the United States.



BtoBE Cable System route


Construction of the nearly 16,000-kilometer optical submarine cable is expected to be completed by the fourth quarter of 2020.


BtoBE, featuring multiple pairs of optical fibre, enables high capacity transmission of data across the Pacific Ocean with round trip latency of less than 130 milliseconds. BtoBE will further enhance and contribute to the much-needed expansion of communications networks between the Guangdong-Hong Kong-Macao Bay Area, San Francisco Bay Area and Singapore. This cable will be built with the most advanced optical submarine transmission equipment, thereby improving network redundancy, flexibility and ensuring highly reliable communications.  


Dr. Li Feng, Chairman & Chief Executive Officer of China Mobile International Ltd. said, “In responding to the increasing data service demand in APAC and the national strategy in developing the Guangdong-Hong Kong-Macao Greater Bay Area, CMI has been committed to enhancing the connectivity capabilities within and beyond the region. CMI successfully completed the laying of the first cross-border optical cable on the Hong Kong-Zhuhai-Macao Bridge in late March 2018. The construction of the BtoBE submarine cable system is another exemplification of CMI’s global network deployment strategy, to cover APAC, extend west, and expand to the world. Upon the operation of the BtoBE cable system, the information flow between the two bay areas will be drastically enhanced and the development of the economy, commerce and culture of the countries in the Pacific Rim will be further fostered.


 NEC is honored to be selected by the BtoBE consortium as the turn-key system supplier for this world record-breaking optical fiber submarine cable system that covers the longest distance without regeneration. The BtoBE, landing at three locations spanning across the Pacific Ocean, is designed so that once completed, it can carry at least 18Tbps of capacity per fiber pair,” said Mr. Akihiko Kumagai, Senior Executive Vice President and head of the Global Business Unit at NEC Corporation. “The BtoBE will provide seamless connectivity and network diversity, while serving to complement other Asia-Pacific submarine cables, among others.


CMI presently owns 138 oversea PoPs and more than 40 submarine and terrestrial cables worldwide, with total transmission bandwidth exceeding 27Tb/s. Moreover, CMI owns terrestrial systems directly accessing 8 neighboring countries of China, which builds CMI a competitive advantage with diversified cross border connections. In the future, CMI will continue to construct its international transmission network with broad coverage, high capacity and short latency to further reinforce the global connectivity.
