Infinera says it has successfully completed a simulated intercity network trial for Telstra InfraCo’s intercity fibre project in Australia, delivering 61.3 Tbps of unregenerated data transmission capacity on a fibre pair over the equivalent of 1,240 route kilometers between Melbourne and Sydney. The network trial was implemented using Infinera’s 800G-capable ICE6 coherent solution and Corning Incorporated’s SMF-28® ULL fibre with advanced bend, demonstrating the high-performance capability of the express network, which is part of the intercity fibre network Telstra InfraCo is building across Australia.

The trial was performed with real-world configurations, including 1,240 kilometres of ultra-low-loss fibre, simulating one of Telstra InfraCo’s planned express Melbourne-Sydney routes. Infinera performed an in-service, non-traffic-impacting upgrade from C-band to combined C-band plus L-band as part of the capacity expansion process. With Infinera’s ICE6 and Corning’s optical fibre, Telstra InfraCo achieved 61.3 Tbps total capacity with 6.2 milliseconds latency across the combined C-band and L-band, with wavelengths up to 700 Gbps.

Telstra InfraCo’s express network is designed to be a high-performance national network for customers who need reliable, ultra-high bandwidth between capital cities and international submarine cable landing stations. For hyperscalers, global cloud providers, content companies, and governments, this means access to scalable high capacity and more direct routes, with optional route redundancy.

“Based on these results, Telstra InfraCo’s express network and overall intercity fibre build will lead the world in scale, low latency, and high data transmission performance rate,” said Kathryn Jones, fiber executive at Telstra InfraCo. “The simulation exceeds our expectations, offering almost seven times today’s typical capacity of 8.8 Tbps per fibre pair and validates our selection of Corning’s SMF-28 ULL fibre in the cable design. This will enable Telstra to develop market-leading solutions for our customers today and for years to come – a key element of Telstra’s ambitious T25 strategy and transformation goals.”

“To meet the rigorous demands of a vast network over Australia’s unique terrain, Telstra InfraCo needed fibre infrastructure with advanced bend capability and minimal signal loss to deliver ultra-high cable capacity. That’s why they turned to Corning,” said Sharon Bois, division vice president, Product Line and Marketing, Corning Optical Fiber and Cable. “Our SMF-28® ULL fibre with advanced bend is designed to meet exactly those needs.”

“Infinera’s 800G-capable ICE6 solution demonstrated industry-leading performance, maximising fibre capacity and reach on Telstra InfraCo’s express network configuration,” said Nick Walden, senior vice president of Worldwide Sales at Infinera. “This achievement underscores the enhanced performance Infinera’s technology can bring to meet Telstra InfraCo’s express network requirements for bandwidth today and into the future.”
