STL Launches India's First Hollow Core Fibre Cable for Data Centre Networks
Mumbai, March 25, 2026 – Sterlite Technologies Ltd [NSE: STLTECH] announced a breakthrough in optical communication with the launch of India's first Hollow Core Fibre (HCF) cable. This innovation is designed to meet the low-latency and high-bandwidth requirements of modern Data Centres, Hyperscalers, and High-Frequency transmission networks.As the first company in India to develop and manufacture HCF technology, STL reinforces its position as a global deep-tech leader. Unlike traditional optical fibres that utilize a solid glass core, STL’s HCF cable guides light through an air-filled core, enabling signals to travel approximately 46% faster and reducing signal loss.
To address diverse network needs, STL has engineered a unique Hybrid Cable architecture that combines Hollow Core Fibre for ultra-low latency and high-power delivery, G.654.E Fibre optimized for long-haul transmissions, and G.657.A1 NOVA fibre for versatility and broad network coverage.
"Our R&D focus has always been on solving the most complex challenges of the future," said Dr. Badri Gomatam, CTO, STL. "With the launch of Hollow Core Fibre cable, we are providing the 'speed-of-light' infrastructure required for the AI revolution."
