As AI workloads continue to grow and may surpass the capacity of individual facilities, institutions increasingly require access to distributed resources across multiple data centres. The ultra-low latency 3.2Tbps AI DCI Superhighway enables AI infrastructure providers to efficiently scale training and inference operations, while empowering institutions such as universities and research labs to run complex scientific simulations by seamlessly pooling computing capacity across Hong Kong.
Upgrading from our 800Gbps AI Superhighway, the 3.2Tbps AI DCI Superhighway supports advanced industry standards including Remote Direct Memory Access (RDMA), RDMA Over Converged Ethernet (RoCEv2), Multipath Reliable Connection (MRC) and Ultra-Ethernet Transport. It will run on the advanced hollow core fibre, which is planned between Lok Ma Chau Loop and Tseung Kwan O, achieving about 30% lower latency than traditional fibre. The combination of high bandwidth and ultra-low latency keeps thousands of GPUs across data centres working in sync, reducing the time and cost of compute by minimising delays in data transmission, while simultaneously lowering power-per-bit to improve energy efficiency.
Steve Ng, Managing Director of Commercial Group, HKT, said, "At HKT, we see connectivity as the critical foundation of Hong Kong's AI future. This next-generation fibre network delivers ultra-low latency, high-speed, and secure data exchange to unlock the full potential of AI development across the city. By seamlessly connecting and maximising Hong Kong's computing resources, we enable faster model training, real-time data processing, and cross-sector AI innovation—strengthening the city's position as a leading I&T hub. It also lays vital groundwork for the Northern Metropolis, linking the Hetao area with existing data centres today while paving the way for seamless access to new computing resources as they come online across the region."
Ricky Kwong, Head of Fixed Network Engineering, HKT and CEO, Fiber Link Global, said, "HKT is firmly committed to supporting innovation in Hong Kong, with the ambition of positioning our city as one of the most advanced I&T hubs in the world. To realise this vision, we are upgrading the AI Superhighway across Hong Kong's major data centre clusters. The first phase, connecting Lok Ma Chau to Tseung Kwan O, is targeted for completion by the end of 2026 and will support the upcoming megawatt-scale Sandy Ridge Data Facility Cluster. Through initiatives such as these, HKT is building the connectivity foundations that will power Hong Kong's I&T ecosystem for years to come."
HKT's AI Superhighway interconnects Hong Kong's leading data centre clusters and HKT's new AI Exchange in the Lok Ma Chau Loop. The Group is also prepared to extend coverage to the upcoming Sandy Ridge Data Facility Cluster, supporting its evolution into an advanced data facility cluster.
