What is FTTH (Fiber to the Home)?
FTTH, Fiber to the Home, means the optical fibre cable runs all the way to the customer's premises, ending in a small device called an ONU or ONT that converts light signals into regular internet. Unlike copper or coaxial delivery, fibre carries data as light, allowing speeds of 100 Mbps to 1 Gbps over kilometres without degradation, immune to electrical interference.
India's broadband growth since Jio Fiber and BSNL Bharat Fibre has been an FTTH story, with local operators wiring entire towns using GPON technology — one fibre from the exchange splits passively to serve 32 or 64 homes, keeping per-home cost low. For customers it means stable speeds during rain, unlike wireless; for operators, the main costs are fibre laying and ONUs at roughly ₹1,000 to ₹2,500 per home.
