Infinera (NASDAQ: INFN) announced today the successful completion of a simulated intercity network trial for Telstra InfraCo’s intercity fiber project in Australia. The trial delivered a leading-edge 61.3 terabits per second (Tbps) of unregenerated data transmission capacity on a fiber 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 fiber with advanced bend, demonstrating the high-performance capability of the express network, which is part of the intercity fiber network Telstra InfraCo is building across Australia.
The trial was performed with real-world configurations, including 1,240 kilometers of ultra-low-loss fiber 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 fiber, 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.
