The Board has approved additional capacity of 4.60 million fibre-km per annum for OF, 5.64 million fibre-km per annum for OFC and 300 MT per annum for preform. Upon completion of the ongoing and proposed expansions, HFCL’s capacities are expected to reach 43.10 million fibre-km per annum for Optical Fibre, 62 million fibre-km for OFC and 600 MT per annum for Preform.

The OF and OFC expansion projects are expected to be completed by July 2028, while the preform manufacturing facility is targeted for establishment by October 2028. The expansion is supported by HFCL’s strong OFC and connectivity order book of approximately INR 19,000 crore, along with growing demand from hyperscale data centres, AI infrastructure, cloud computing, telecom expansion and fibreisation.
