Grosvenor Mine: High-Capacity Fibre Optic Run
The Challenge
Grosvenor Coal Mine required a reliable, high-capacity data backbone to connect critical operational systems across multiple sites spanning 5km. The mine needed to install dual 48-core singlemode OS2 fibre optic cables linking control nodes from the MIA server room through the conveyor drift infrastructure to remote monitoring stations---all while working within existing buried conduit systems to minimise site disruption.
Our Approach
Deftec designed and delivered a complete fibre infrastructure solution including cable supply, installation labour, termination enclosures, and professional supervision. We coordinated with specialised cable installation partners to safely pull dual 48-core cables through pre-existing conduit runs using trained winch operators, then terminated all cores into loaded SC sliding enclosures at eight separate termination points across the site. The 14-day on-site installation programme was supported by experienced personnel and all work was carried out to AS/CA S009:2020 standards for outdoor cabling installations between premises.
The Outcome
Grosvenor now has a robust, future-proofed fibre backbone capable of supporting significant data throughput across their operation. The dual-fibre redundancy provides resilience for mission-critical mining systems, while the 48-core capacity per run offers substantial headroom for expanding connectivity as operational requirements evolve. All terminations were professionally documented and integrated into cable distribution records.
