AI workloads, distributed cloud, and edge growth are pushing capacity limits across metro and data-centre routes. Yet ducts are congested, deployment timelines are tight, and sustainability benchmarks are rising.
At STL, we are addressing this challenge through spatially multiplexed Multicore Fibre (MCF) - a field-validated fibre architecture that delivers up to 4 times the capacity in the same 125-micron geometry. It interoperates seamlessly with existing single-mode networks using standard fan-in/fan-out modules, enabling scalable upgrades without the need for trenching or new duct construction. During OFC 2026 in Los Angeles, you can visit the ITU booth (#4874 and #4876) to see the live demonstration of STL's multicore fibre.
Key advantages
4 independent spatial channels in each fibre
Lower footprint
Proven deployment in live field environments
Quantum-aware channel isolation for future security requirements
This architecture is particularly relevant for:
Metro densification and brownfield upgrades
Data-center campus and regional DCI
Rail, defense, and mission-critical corridors
Operators targeting high capacity with low environmental impact
