Nokia builds multi-terabit pan-Indian optical network for Bharti Airtel

  • Bharti Airtel will deploy Nokia’s Optical Transport Network (OTN) technology across its nationwide footprint.
  • Revamped optical network will transform India’s digital infrastructure and enable Bharti Airtel to provide massive capacity to enterprises, operators and hyperscalers.
  • New optical network allows enterprises to thrive in the growing digital economy.


21 November 2023
New Delhi, India – Nokia today announced it 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 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, datacenter 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 utilizing additional spectrum including the L-band wavelengths of the fiber. 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 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. 

Chandan Kumar, Head of Optical Network Business Centre for Nokia India , said: “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”.
