Harmonic Inc. announced on November 10, 2026, that Swiss telecommunications provider Quickline AG is deploying Harmonic's cOS virtualized broadband platform to replace legacy CMTS hardware and launch managed broadband services for regional ISPs.

Key Highlights

  • Platform deployment: Quickline AG is replacing decentralized CMTS hardware with Harmonic's cOS virtualized broadband platform, according to the filing.
  • Wholesale network scale: Quickline currently supports 23 independent network operators across Switzerland through its nationwide backbone infrastructure.
  • New revenue model: The cOS platform enables Quickline to extend fully managed broadband services to additional regional broadband providers, the filing disclosed.
  • Operational benefits cited: The company disclosed that the transition is designed to centralize network administration, reduce operational complexity, and lower power and space requirements.
  • Global platform reach: Harmonic reported that its cOS platform powers services through more than 52 million CPE devices worldwide.
  • Market position claimed: Harmonic described itself as "the market share leader in cable broadband equipment, virtual CMTS and DAA, according to Dell'Oro Group."

Quickline's Shift to Software-Based Infrastructure and Managed Services

According to the filing, Quickline AG, a Swiss telecommunications provider acting as a wholesale broadband operator, is modernizing its network by transitioning from legacy integrated CMTS hardware to Harmonic's cOS virtualized broadband platform. Harmonic trades on NASDAQ:HLIT. The filing states that this software-based architecture is intended to provide a "flexible foundation for continuous network evolution" while simplifying operations and reducing power and space requirements.

Torsten Schubert, Head of Network Engineering at Quickline AG, was quoted in the filing as stating that the platform "allows us to replace complex, decentralized CMTS hardware with a software-based architecture that can scale with subscriber demand." The filing further notes that Quickline's centralized approach is meant to streamline monitoring and maintenance and enhance service reliability across the 23 regional network operators it supports in Switzerland.

The filing also highlighted a commercial dimension to the deployment. By adopting the cOS platform, Quickline aims to offer fully managed broadband infrastructure as a service to additional regional ISPs, allowing those providers to access centralized broadband capabilities without deploying their own virtualized core. Stefan Meier, Vice President of Sales, Europe, at Harmonic, was quoted as saying the arrangement "creates a scalable managed service model that can help smaller operators modernize their networks with greater speed and confidence." The filing noted that statements regarding anticipated capabilities and market growth are forward-looking and subject to risks described in Harmonic's regulatory filings, including its Annual Report on Form 10-K for the year ended December 31, 2025.
