Sterlite Technologies collaborates with Colt Technology Services

Sterlite Technologies has collaborated with Colt Technology Services (Colt) for the Multi-Core Fibre (MCF) trials executed across Colt’s London metro optical network in London, UK. This marks a significant milestone in real-world validation of MCF technology as a sustainable, high-capacity, cost-efficient backbone for next-generation networks supporting AI, cloud, and digital services.

During the trial, the company’s Multiverse Multi-Core 4-core Fibre-built in the same cladding diameter as standard singlemode fibre (SMF)-was deployed. The trial was conducted within the London Metro network between two Colt PoPs, covering distances of around 9 km and 63 km. An 800 Gbps line rate was achieved with validation performed for 100GE and 400GE services. Comprehensive testing was carried out, including Chromatic Dispersion (CD), Polarization Mode Dispersion (PMD), Crosstalk, Throughput, Fault analysis, OTDR, Loss, and Optical Return Loss (ORL) measurements, all of which delivered satisfactory results.

Sterlite Technologies is one of the industry's leading integrators of digital networks providing All-in 5G solutions.
