Telstra International delivers major capacity boost across key Asia Pacific routes

16 October 2025 — Telstra International, the global arm of telecommunications and technology company Telstra, has made significant progress in the performance and flexibility of its Asia Pacific subsea cable and backhaul network, with incremental 200Tbs, reflecting a 30% increase in total network capacity across key Asia Pacific routes.

As part of its roadmap to a highly autonomous, secure and resilient network, Telstra International has deployed the latest optical technologies – Ciena's WaveLogic 6 Extreme (WL6e) and Nokia’s Infinite Capacity Engine 7 (ICE7), optimising capacity and providing resilience to meet the insatiable customer demand for data and connectivity.

With the flexibility to scale with business needs, its network infrastructure cloudification strategy significantly shortens capacity provisioning lead times from months to weeks and days, enabling the rapid and efficient delivery of capacity.

“This year, we’re on track to fully cloudify our subsea and backhaul network,” said Roary Stasko, CEO Telstra International.

“We’ve made strong progress in cloudifying the transport infrastructure layer, allowing us to provision services rapidly and scale high bandwidth to demand—where and when our customers need it. Telstra International is among the industry leaders collaborating with both Ciena and Nokia to introduce the cloudification of digital infrastructure.”

With the latest technology now commercialised across the international footprint, Telstra International is offering 400G services over diverse routes, with a roadmap to roll out 800G services in the future, providing the capacity customers need for large scale data centre interconnect and high bandwidth demand.

Telstra International continues to advance its highly autonomous network strategy, with plans to introduce predicative capacity management and service performance level capabilities. This vision is central to Telstra’s Autonomous Network (TAN), which is transforming network operations into a highly autonomous, data-led, Artificial Intelligence (AI) driven, API-first architecture by 2030.

“These technologies will help us to execute our network transformation ambition under our Connected Future 30 strategy, which includes developing our Network as a Product and investing in infrastructure over the five-year strategic plan. We’re focused on elevating the customer experience by infusing AI into our network, with dynamic traffic management, incident avoidance and enhanced network security,” said Roary.
