High-Capacity Subsea Network Design
The JGA cable system will span 9,500 km and deliver more than 36 terabits per second (Tbps) of capacity. The consortium expects to complete the project by the fourth quarter of 2019.
This high-capacity system will support growing data demand and strengthen international communication networks.
Dual-Segment Structure Enhances Connectivity
The project includes two key segments. First, JGA South (JGA-S) will connect Sydney, Australia to Guam and includes partners such as AARNet, Google, and RTI-C.
Next, JGA North (JGA-N) will link Japan to Guam. RTI-C serves as the sole purchaser for this segment. Both systems will connect at Guam’s landing station, improving network integration.
Strengthening Global Network Infrastructure
The Japan Guam Australia cable system will improve network redundancy and ensure more reliable communications. In addition, it will expand connectivity between Japan, Australia, Asia, and the United States.
This system also introduces critical north-south connectivity across the Pacific. As a result, it complements existing east-west routes and improves global data flow.
Supporting Future Cable Investments
The project builds on previous initiatives supported by the Japan ICT Fund and reinforces ongoing investment in subsea infrastructure. Companies involved plan to expand similar projects to meet future connectivity needs.
