On September 29, 2025, Harmonic Inc. and Comcast announced a partnership to expand fiber broadband access across new markets. The announcement, made at 08:00 ET, highlights the use of Harmonic’s cOS virtualized broadband platform and network edge devices as a core component of Comcast’s multi‑gigabit, low‑latency service rollout.
The collaboration will allow Comcast to deploy multi‑gigabit symmetrical broadband with low latency by integrating Harmonic’s cOS platform with both fiber and existing DOCSIS infrastructure. The partnership also supports BEAD‑funded projects and rural community rollouts, providing cost‑effective fiber deployments that coexist with coaxial networks.
For Harmonic, the deal represents a significant customer win with one of the largest U.S. broadband operators, expanding its footprint in the U.S. market and reinforcing its leadership in virtualized broadband solutions. The partnership is expected to drive revenue growth in the Broadband segment and strengthen Harmonic’s competitive moat.
