Tata Communications plans to invest $400–450 million in about 10,000 km of new long-haul fibre across India. Announced on 26 October, the project would connect AI data-centre clusters with international cable landing stations.[1]
The rollout is planned in phases, beginning with the Mumbai–Pune–Hyderabad–Chennai corridor. Later expansion would reach Visakhapatnam, Bhubaneswar, Jamnagar and GIFT City. Tata is also expanding its existing metro and national networks.[1]
How the connection serves the computers
Tata’s technical guide to data-centre interconnect describes links that let sites share data, replicate it and move workloads between locations. Fibre provides the physical connection. Network equipment directs the traffic, while wavelength-division multiplexing carries separate streams of data on different wavelengths of light within a fibre.[2]
The route and the traffic it can carry are therefore different parts of a network. A kilometre count describes physical reach; optical equipment and network configuration determine how a connection is used.[2]
For example, maintaining a current copy of a dataset at a second site makes the connection an ongoing part of the service. Data must move between the sites before that copy can support recovery from an outage.[2]
