Swisscom and Nokia have successfully brought Swisscom’s nationwide Next Evolution Wavelength Transport Optical Network (NEWTON) to life, and officially commenced the service migration to this state-of-the-art network. With high traffic growth and digital transformation in mind, Nokia’s optical networking solution will grant Swisscom, the largest telecom provider in Switzerland, a service-centric network. This unique network is optimized for high performance, cost efficiency, and superior customer experience.

The sudden rise in remote work and learning applications, video streaming, gaming, and cloud computing placed the spotlight on Swisscom’s 2021 ambition to provide robust support for business-critical fixed and wireless traffic. Swisscom chose Nokia’s range of optical networking hardware, software, and professional services for this complete transformation. This upgrade included the rollout of 22 backbone sites and 560 metro sites.

With the rollout completed before the deadline, both companies will now move to oversee the migration of services to the updated network. This new optical network will be responsible for transporting all of Swisscom’s fixed and wireless traffic, from customer-supplied equipment to metro access to the backbone. Catering to client services ranging from 1G to 400G, the network will efficiently handle traffic end-to-end while maximizing fiber usage. This solution will handle massive traffic growth by eliminating repetitive tasks, expediting service delivery, and reducing overall ownership costs. The substantially lower power consumption is also a noteworthy innovation, contributing to Swisscom’s sustainability goals by minimizing its carbon footprint.

Christoph Aeschlimann, CEO at Swisscom said, “The transformation of Swisscom’s optical network is essential for our future digitalization. Through the partnership with Nokia, we have a network that can adjust swiftly to changes and provide superior service to our customers while also aligning with our sustainability goals. We are thrilled to transit to this next stage of service migration, together with Nokia as our trusted partner.”

Federico Guillén, President of Network Infrastructure, Nokia, shared his pride about collaborating with Swisscom on the modernization of its optical transport network. He said, “This is a showcase service-centric network, fully leveraging automation to streamline service delivery and minimize costs, even as it seamlessly scales to support surging customer traffic demands.”

For this complete transformation, Swisscom chose Nokia’s portfolio, 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.
