STL and Colt Validate Multi-Core Fibre for Next-Gen Optical Networks in UK Trial
Event summary
- STL and Colt completed a successful trial of Multi-Core Fibre (MCF) across Colt’s London metro optical network.
- The trial achieved an 800 Gbps line rate and validated 100GE and 400GE services over distances of ~9 km and 63 km.
- STL’s Multiverse™ MCF packs 4 cores into the same cladding diameter as standard single-mode fibre (SMF).
- The trial included comprehensive testing for Chromatic Dispersion, Polarization Mode Dispersion, Crosstalk, and other performance metrics.
The big picture
The successful trial of MCF technology marks a significant step in the evolution of optical networking, addressing the surging demand for bandwidth in AI, cloud, and digital services. STL’s ability to deploy MCF in real-world environments positions it as a leader in sustainable, high-capacity connectivity solutions. This development underscores the growing importance of collaborative innovation in advancing next-generation network infrastructure.
