Swisscom completes nationwide Next Evolution Wavelength Transport Optical Network (NEWTON)

Nov. 20, 2023
The new network leveraging Nokia’s optical platforms will support more incredible service speeds and capabilities.

Swisscom, in partnership with Nokia, has wrapped up tis nationwide Next Evolution Wavelength Transport Optical Network (NEWTON) and the official start of service migration to the modernized network.

Like other incumbent providers, Swisscom faced a surge in remote work and learning applications, video streaming, gaming, and cloud computing. These factors intensified Swisscom’s goal in 2021 to bolster support for business-critical fixed and wireless traffic.

The carrier selected Nokia’s optical networking hardware, software and professional services for the entire transformation, including the rollout of 22 backbone sites and 560 metro sites.


Having completed the network deployment ahead of schedule, Swisscom and Nokia will now jointly manage the migration of services to the modernized network. The new optical network will transport Swisscom’s fixed and wireless traffic from customer-provided equipment to metro access to the backbone, supporting client services from 1G to 400G and aggregating and managing traffic while maximizing fiber usage. The solution will address traffic growth by eliminating repetitive tasks, accelerating service delivery, and reducing ownership costs.

Network speed and management aren’t the only benefits of the new network. This new network will operate with lower power consumption – one of Nokia's optical portfolio innovations– and contribute to Swisscom’s corporate sustainability goals by reducing its carbon footprint.

Swisscom selected Nokia’s portfolio of optical networking hardware, software and professional services for the entire transformation, including the Nokia Photonic Service Engine (PSE)-V powered 1830 family of Wavelength Division Multiplexing/Optical Transport Networking (WDM/OTN) platforms and the WaveSuite portfolio of networking applications.

“The transformation of Swisscom’s optical network is essential for our future digitalization,” said Christoph Aeschlimann, CEO of Swisscom. “Through the partnership with Nokia, we have a network that can quickly adapt to changes and provide superior service to our customers while contributing to our sustainability goals.”
