HFCL has joined the consortium of a Department of Telecommunications (DoT) - funded research project led by the Indian Institute of Technology, Delhi (IIT Delhi) focused on advancing hollow-core fiber (HCF) technology for next-generation communication networks. The project aims to develop novel optical fiber technologies relevant to future 6G and quantum communication systems. As a consortium partner, HFCL will contribute industry expertise, manufacturing perspective, and application insights to support the translational aspects of the research.

Hollow-core fiber is an emerging optical technology designed to reduce transmission latency and enhance signal performance compared to conventional solid-core fiber. Globally, it is being explored for high-capacity, long-haul, and latency-sensitive network applications, including advanced data centers and next-generation telecom infrastructure.

With increasing AI workloads, hyperscale computing demand, and the evolution toward 6G networks, the need for ultra-low-latency optical infrastructure is expected to grow significantly. The DoT-supported initiative seeks to strengthen India’s indigenous capabilities in this strategically important domain. Hollow-core fiber can dramatically reduce energy consumption and reduce latency in data communication.

HFCL is a leading telecom infrastructure developer, system integrator and manufacturer of high-end telecom equipment and optical fibre cables, having its own manufacturing facilities at Solan and Goa, and its subsidiary i.e. HTL facilities in Chennai and Hosur.
