Harmonic has announced that Quickline AG, a Swiss telecommunications provider, is modernizing its infrastructure with Harmonic’s cOS™ virtualized broadband platform. The operator’s transition to a software-based broadband architecture creates a flexible foundation for continuous network evolution, while simplifying operations and reducing power and space requirements.
This transition also enables Quickline to speedily introduce fully managed broadband services for additional regional ISPs, creating new revenue opportunities.
“As a wholesale broadband provider supporting 23 regional network operators, we needed a platform that gives us the flexibility to grow and introduce new services,” said Torsten Schubert, Head of Network Engineering at Quickline AG. “Harmonic’s cOS virtualized broadband platform allows us to replace complex, decentralized CMTS hardware with a software-based architecture that can scale with subscriber demand. At the same time, it creates new pathways for us to deliver managed broadband services to our regional partners.”

Centralized Infrastructure for Simplified Operations
By transitioning from legacy integrated CMTS hardware to Harmonic’s virtualized cOS platform, Quickline can overcome the traditional limitations of hardware-based infrastructure. This transformation enables Quickline to centralize network administration, streamline monitoring and maintenance, reduce operational complexity and enhance overall service reliability.
New Wholesale Model for Regional Operators
Quickline currently supports 23 independent network operators across Switzerland through its nationwide backbone infrastructure. Harmonic’s high-availability cOS platform allows Quickline to extend its fully managed broadband services to additional regional broadband providers, giving them access to a centralized broadband infrastructure without requiring them to deploy and manage their own virtualized core. This model creates a new wholesale revenue opportunity for Quickline and gives regional providers a practical path to evolve their networks.
“Quickline’s adoption of the cOS platform is a great example of how broadband virtualization can help operators move beyond hardware limitations, accelerate network innovation and create new revenue streams,” said Stefan Meier, Vice President of Sales, Europe, at Harmonic. “Quickline is not only modernizing its own infrastructure but also creating a scalable managed service model that can help smaller operators modernize their networks with greater speed and confidence.”
Harmonic’s cOS platform powers next-generation broadband services through more than 52 million CPE devices worldwide for leading operators across North America, Europe, Latin America and Asia.
