Nokia to deploy optical backbone for WINDTRE

Vi revamps backbone network with Ciena

Vodafone Idea Limited is revamping the backbone scalability and service resiliency by deploying 5th generation coherent optical solutions fromCiena. As consumers, enterprises, and content players look to embrace smarter digital experiences across India, Vi’s new 300G/400G backbone network increases scale and performance in an energy and cost-efficient manner. Vi has deployed Ciena’s 6500 packet-optical platform powered by WaveLogic 5 Extreme for high speed 300G/400G services, upgradable to 800G, with the ability to tune capacity for maximum agility while also reducing energy consumption. Vi says it has forged partnerships with several technology leaders, ecosystem players and Indian start-ups for developing a range of 5G use cases relevant for Indian enterprises and consumers.

It’s collaboration with Ciena is in line with the service provider’s strategy to build a future-fit network for emerging technologies such as 5G, to drive digital growth in India. Increasing and changing traffic patterns across India require new levels of capacity, flexibility, resiliency, and programmability. With broader network coverage and faster broadband made possible by Ciena, Vi maximises fibre capacity and network efficiencies to prepare for 5G. “Escalating demand for data requires a high-capacity and resilient network that can thrive not only today but for years to come,” said Jagbir Singh, chief technology officer, Vodafone Idea Ltd. “Preparing a future-fit network, through our partnership with Ciena, will enable Vi subscribers to experience world-class highly available, scalable connectivity and realise the benefits of cloud, IoT, and 5G in future.”

Nokia has been selected by WINDTRE in Italy to deploy a new, high performance optical backbone. At the heart of WINDTRE’s nationwide network infrastructure, the photonic backbone will bear traffic from the entire country, addressing the growing demand for ultra-fast connectivity as well as delivering high-capacity services to business customers. The DWDM solution will leverage Nokia’s fifth generation PSE-V super- coherent (PSE-Vs) chipset to support programmable line rates up to 600G on a pure photonic infrastructure, optimising power consumption and footprint. With redundant nodes in a

wave router configuration, a mesh structure and GMPLS-based restoration, the new backbone will be able to instantly re-route traffic as needed, providing the high reliability and robustness required in this business-critical part of the infrastructure. Benoit Hanssen, chief technology officer at WINDTRE, said, “Nokia’s solution based on industry- leading coherent technology will help us provide next generation broadband services to both consumer and business customers in the most efficient way. It will also enable us to grow our subscriber base and provide best-in-class experience to WINDTRE’s existing customers.”
