Between the coast of Chennai and the beaches of the Andaman & Nicobar Islands archipelago, there’s a 2,300 kilometre network of submarine optic fibre cables. The Chennai-Andaman & Nicobar Islands system, or CANI for short, is the only submarine cable that serves Indian territory alone — a similar system for the Lakshadweep Islands is being planned. Systems like CANI — at a larger, intercontinental level — are what makes the global nature of the internet possible, offering several terabits per second of broadband capacity between countries.
