Harmonic Spotlights Fiber Breakthroughs at Network X 2025

SAN JOSE, Calif. - Oct. 9, 2025 - Harmonic (NASDAQ: HLIT) is bringing its powerful fiber broadband innovations and deep expertise in accelerating fiber deployments to Network X 2025 in Paris. Harmonic's market-leading cOS virtualized broadband platform and extensive ecosystem of fiber solutions enable operators to deliver multi-gigabit broadband connectivity with greater efficiency and significant cost savings, unlocking new revenues and fueling sustainable subscriber growth.

As fiber rollouts across EMEA gain strong momentum, operators are looking for trusted solutions that deliver efficiency, reliability and third-party interoperability, said Stefan Meier, vice president of broadband sales, EMEA, at Harmonic. Harmonic is leading the way with innovative fiber solutions, empowering operators to expand their broadband service network, reduce deployment complexity and meet rising connectivity demands. Our recent collaboration with neu-medianet in Germany underscores this leadership as we continue to drive fiber progress and help operators accelerate fiber service velocity.

Harmonic will showcase breakthrough innovations at Network X 2025 that allow operators to:

Accelerate fiber-grade broadband to MDUs: Harmonic's SeaStar optical node transforms broadband delivery for lower-density MDUs, offering a cost-effective and rapid track to fiber-grade connectivity in brownfield environments. SeaStar brings multi-gigabit broadband connectivity to MDUs without rewiring, helping operators lower capital costs and boost new revenue opportunities.

Adopt a future-forward fiber service strategy: Harmonic's cOS broadband platform, along with Pearl R-OLTs, Jetty remote switches and Pier OLT shelves, provides a seamless, future-ready path from GPON to XGS-PON, 25GS, 50G, 100G and beyond. These solutions enable cost-effective scaling to meet growing demand for high-speed fiber connectivity.

Break free from vendor lock-in and build future-ready networks: Harmonic's Open ONT approach gives operators the freedom to select CPE devices that best meet their needs. At Network X, Harmonic will highlight real-world interoperability and flexibility enabled by this approach.

Harmonic's cOS platform powers next-gen broadband services through more than 35 million CPE devices worldwide for leading operators in North America, Europe, Latin America and Asia.
