Swisscom modernises network for faster service and scalability

Swiss network provider, Swisscom is transforming its existing infrastructure to create a fully automated and higher capacity transport network. 

The upgraded 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. This requires a scalable and upgraded infrastructure that can grow capacity while increasing performance and resilience. 

Nokia has been selected as the sole supplier to build the end-to-end wavelength division multiplexing/optical transport network (WDM/OTN). Its portfolio of optical networking hardware, software and services will be used. This includes Nokia WaveFabric, based on the 1830 family of WDM/OTN platforms powered by the Nokia PSE-V coherent digital signal processor (DSP), and the Nokia WaveSuite portfolio of networking applications for network commissioning, service enablement, and network health and analytics. 

Additionally being deployed is the company’s WavePrime Digital Twin as a Service, which provides a cloud-hosted digital representation or simulation of the physical network to design, replicate, test and analyse in order to optimise physical network performance and reliability. 

Christoph Aeschlimann, CIO and CTO at 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. This strategic partnership highlights Swisscom’s commitment to delivering a high capacity, fully automated nationwide optical backbone for Switzerland.’

James Watt, head of optical networks division at Nokia, said: ‘We are providing a complete, customer-focused and business driven solution that will transform Swisscom’s optical transport network into a service engine that’s ready to deliver new services. Swisscom will also benefit from a more automated network that streamlines service delivery and optimises its total cost of ownership, creating value for both its business and customers.’
