Tata Communications plans to spend close to $450M on about 10,000km of new long-distance fibre across India, built to connect the country's AI data-centre hubs.
The Mumbai-based company, which sells data connections and cybersecurity services to businesses, set out the plan in a stock exchange filing, as reported Monday. Long-distance fibre is the optical cable that carries data between cities and regions, as opposed to the local links that reach homes and offices.
The spending works out to roughly $45,000 per km, our arithmetic from the two headline figures. The company did not frame it that way, and real costs vary with terrain and route.
The notable part is the target. This is a network aimed at data centres, the buildings full of servers where AI models are trained and run, rather than at consumers. Those sites need fast, dependable links to each other and to customers, and a carrier that already sells connectivity to businesses has an obvious reason to build them. The money goes to the pipes, not the chips.
The details reported so far do not include a timeline or a list of routes. Those would show whether this is a backbone for a few existing hubs or a bet on ones that do not yet exist.
