Nokia to build multi-terabit capacity pan-Indian optical network for Bharti Airtel

The technology will help the Airtel network from disruption caused by optical fibre cable damage as the transport layer will reroute the traffic through other cable links.

Airtel will utilize Nokia’s 1830 PSS-x OTN switches in its National Long-Distance Network connecting major cities across India.

Finnish telecom gear maker Nokia has entered into an agreement with Bharti Ltd (Airtel) to deploy a next-generation optical transport network that will provide additional capacity, higher reliability and lower cost, enabling superior services for Airtel’s customers.

"As part of the agreement, Airtel will utilize Nokia’s 1830 PSS-x OTN switches in its National Long-Distance Network connecting major cities across India," the company said in a statement.

“As a world leader in OTN, our technology will help Airtel to increase the capacity and features of Bharti’s optical transport network to meet growing bandwidth demand driven by the enterprise and hyperscaler segments. It will also provide the service level performance to meet the strict SLAs from Airtel customers,” said Chandan Kumar, Head of Optical Network Business Centre for Nokia India.

To address this exponential growth in traffic demand, transport networks need to be upgraded to increase overall transport capacity and bandwidth efficiency using high-capacity OTN switching and utilizing additional spectrum including the L-band wavelengths of the fibre. The increased capacity will mean that Bharti can potentially deliver faster and more reliable broadband services and be ready for new use cases.

The Nokia OTN solution will enable Bharti Airtel to seamlessly upgrade its legacy transport switching infrastructure across its pan-Indian network footprint to meet new transport network traffic demands while improving both the performance and reliability of its network.
