Nokia to transform Swisscom’s optical transport network

11 May 2021

Nokia has been selected by Switzerland telecom Swisscom to fully automate and expand its capacity for its optical transport network.

Nokia will be the sole supplier to build an end-to-end wavelength division multiplexing/optical transport network (WDM/OTN) nationwide to support bandwidth demands driven by an increase in remote work and learning applications, video streaming, gaming and cloud computing.

The optimized network will transport all of Swisscom’s fixed and wireless traffic from customer-provided equipment to metro access to the backbone and will support client services from 1G to 400G. Nokia will provide a scalable and upgraded infrastructure that can grow capacity while increasing performance and resilience.

Nokia’s optical networking hardware, software and professional services will be used for the entire transformation. This includes Nokia WaveFabric and Nokia WaveSuite portfolio of networking applications for network commissioning, service enablement and network health and analytics. Nokia will also deploy its WavePrime Digital Twin as a Service for cloud-hosted digital representation or simulation of the physical network to design, replicate, test and analyze the physical network performance and reliability.

Christoph Aeschlimann, CIO and CTO, Swisscom, said: “Swisscom has set out its network expansion strategy until the end of 2025, which is to equip the network for the new decade,” said Chrisoph Aeschlimann, CIO and CTO at Swisscom. “This strategic partnership with Nokia highlights Swisscom’s commitment to delivering a high capacity, fully automated nationwide optical backbone for Switzerland. This next-generation transport network can quickly adapt to changes and provide superior services and connectivity experiences to our customers. Nokia has proven to be a trusted partner and has been the preferred choice to transform our optical network.”
