Intercity Dark Fibre Network
We're building the Intercity Dark Fibre network of the future
A hyper-connected network to support all communities
Over the next five years to 2027, Telstra will be boosting its national fibre network, with new fibre paths being installed across the country. The new fibre paths will boost capacity and speed to meet the needs of tomorrow’s connectivity between cities, regional and remote communities. Using leading ultra-low loss technology and strategically positioned amplification sites, this network will support remote working and education, health services, entertainment, online gaming and IoT applications for mining and agriculture.
Why Intercity Dark Fibre Network will work for your business
Express network
It will enable direct high-data fibre connectivity between capital cities (with no breakouts).
Fast speeds
Express transmission between Australia’s biggest cities to enable target transmission rates of up to 650Gbps per channel, which can equate to up to 50Tbps per fibre pair.
Accessibility and resilience
National ramp will enable break out approximately every 5km at every optical joint/ building. Equating to approximately 4,000 ramp on and off points nationally without interfering with the network.
Durability
Cable design is proven to withstand Australia’s unique environmental conditions and designed to reduce carbon footprint.
Monitoring
We employ fibre sensing technology for real-time optical fibre performance metrics enable predictive action and rapid fault localisation.
When built, the network could be considered the largest, most advanced long-haul terrestrial network deployed anywhere in the world to date.

Future-proofed features
Express network
An ultra-low loss fibre (Corning SMF-28 ULL wAB) will provide reliable, super-high bandwidth between capital cities and international submarine cable landing stations. The new network will deliver greater performance and capacity, high-data-rate, dark fibre services, and will have a flexible design for future connectivity to non-capital city data centres and data centre hubs.
Foundation network
A low-loss fibre (Prysmian BBA2) renewal/upgrade of the existing intercity network with technically improved fibre, cable, and architecture. It will provide additional capacity between capital cities, enhance performance and improve connectivity to regional Australia to support the anticipated growth in bandwidth over the next 25+ years.
Collaborating with the best to deliver an ultra-low latency network
Whitepapers from our collaborators, Corning and Infinera, discuss the technologies and techniques that will be used to deliver our new high-performance intercity fibre network build. This market-leading customer solution is one of Telstra's long-term transformation strategy goals.
