Nokia on Tuesday announced it has entered into an agreement with Bharti Airtel to deploy a next-generation optical transport network (OTN) that will provide additional capacity, higher reliability and lower cost, enabling superior services for Airtel's customers.

Under the agreement, Airtel will utilise Nokia’s '1830 PSS-x OTN' switches in its National Long-Distance Network connecting major cities across India.

"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," Chandan Kumar, Head of Optical Network Business Centre for Nokia India, said in a statement.

The increased capacity will enable Airtel to potentially deliver faster and more reliable broadband services and be ready for new use cases, Nokia said.

According to the company, its OTN solution enables 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.

Nokia noted that the launch of 5G networks and the push for broadband connectivity across India is increasing demands for Communications Service Providers (CSPs), including augmentation of backhaul transport for denser 5G mobile networks, wholesale connectivity for new segments like smart grids, data centre interconnect (DCI) and other business services.

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 utilising additional spectrum, including the L-band wavelengths of the fibre, it added.
