Delivering Next-Generation Global Connectivity

A next-generation submarine cable infrastructure delivering high-capacity international bandwidth, real-time environmental monitoring, and advanced industrial sensing.

The 576 Tbps Subsea Cable

The system is a next-generation subsea cable infrastructure linking the Pacific, Southeast Asia, and South Asia through a high-capacity international network. It delivers 576 Tbps of initial capacity, scalable to 1,152 Tbps, supporting long-term growth in international bandwidth demand.

 

Capacity upgrades are achieved through optical transmission enhancements without the need for new submarine fiber deployment, enabling efficient scalability as digital demand increases. The submarine cable system is manufactured and deployed by Alcatel Submarine Networks, a global provider of submarine cable infrastructure.

 

The system integrates Scientific Monitoring and Reliable Telecommunications (SMART) technology, combining high-capacity communications with real-time environmental sensing.

High-Capacity International Bandwidth

Provides scalable, low-latency transmission of large volumes of data across international networks, forming the foundation for hyperscale data centers, cloud platforms, and artificial intelligence workloads.​

 

This capability enables continuous cross-border data exchange and supports the expansion of regional digital economies.

Seagate Subsea Cable

Real-Time Environmental Monitoring

Integrates embedded sensors within the cable system to measure temperature, pressure, and seismic activity along the seabed in real time.

​​

These capabilities enable:

​​

  • earthquake detection

  • tsunami monitoring and early warning

  • ocean condition observation

  • global warming monitoring

  • sea level rise monitoring

​

and contribute to improved disaster preparedness, climate monitoring, and long-term environmental analysis.

Industrial Sensing

Utilises fibre-based sensing technologies to continuously monitor subsea conditions and infrastructure along the cable route.

 

This includes:

 

  • detection of seabed movement and vibration

  • pipeline monitoring

  • gas leak detection

  • subsea asset integrity monitoring

  • detection of unauthorised activity or external interference

  • tracking of environmental conditions affecting offshore operations

 

These capabilities reduce operational losses, minimise unplanned shutdowns, extend asset lifespan, and enhance production efficiency.

Seagate Networks Market Demand

Market Demand

Demand for international bandwidth is expanding at scale, driven by structural growth in data infrastructure, cloud computing, and high-intensity digital workloads.

 

This growth is sustained, multi-sector, and requires continuous expansion of high-capacity, low-latency international connectivity.

Data Centers & Hyperscalers

Ongoing deployment of hyperscale data centres is driving consistent demand for large-scale international bandwidth.

 

Capacity requirements are shaped by:

 

  • interconnection between regional and global data centres

  • high-throughput data exchange across distributed architectures

  • redundancy and route diversity requirements
