Project Horizon will see Vocus deploy the first competitive fibre backbone between Perth and Port Hedland, and is the first major infrastructure project under Vocus' $1 billion investment program. When complete, Project Horizon will close the final gap in Vocus' national fibre backbone connecting all mainland capitals. Horizon will also interconnect with two high-capacity submarine cables in Port Hedland, establishing Australia's north as a new hub for domestic and international data.

As a fibre partner for project Horizon, STL will support Vocus' network rollout with a state-of-the-art design, combined with high-tensile and crush strength cable technology. The cables have a design life of more than 30 years, ensuring Project Horizon will continue to deliver high-capacity connectivity through the Pilbara until the 2050s even in harsh environmental conditions.
