Insights
Harmonic secures major DOCSIS 4.0 deal with Mediacom, strengthening its dominant market position in cable broadband infrastructure.
This partnership with Mediacom Communications represents a significant win for Harmonic in the competitive broadband infrastructure space. Mediacom, as the fifth-largest cable operator in the US, provides Harmonic with another major reference customer for its cOS virtualized platform and DOCSIS 4.0 technology.
The deal's strategic importance extends beyond just another client win. Harmonic now serves 8 of the 10 largest cable operators in the US, confirming its market leadership position according to Dell'Oro Group data. This dominant position creates a powerful network effect, making it increasingly difficult for competitors to displace Harmonic in future deployments.
Technically, Harmonic's Unified DOCSIS 4.0 solution offers unique advantages. Their innovative PTP-less virtualized core eliminates the need for a separate timing network, which significantly reduces deployment complexity and operational costs for operators. This differentiator addresses a critical pain point in distributed access architecture implementations.
The deal also validates Harmonic's strategic technology bet on supporting both Full Duplex (FDX) and Frequency Division Duplex (FDD) approaches within a unified architecture. This flexibility allows cable operators to modernize their networks while preserving options for eventual fiber transitions – creating a compelling migration path that extends customer lifetime value.
What's particularly noteworthy is Mediacom's position as one of the first North American operators to launch DOCSIS 4.0 services, placing Harmonic at the forefront of next-generation broadband deployments. With 33 million CPE devices already powered by Harmonic's platform globally, this deployment further cements the company's technology leadership and expands its addressable market in cable infrastructure modernization.

"As we prepare our network to embrace the future of broadband, we needed a partner with deep DOCSIS 4.0 expertise and a proven track record," said JR Walden, CTO at Mediacom. "We chose Harmonic for their clear leadership in innovative technology, unparalleled scalability across diverse deployments and robust installed base. Partnering with Harmonic will enable us to deliver ultra-fast broadband connectivity and outstanding quality of experience leveraging DOCSIS 4.0 technology."
With this deployment, Harmonic continues to expand its broadband industry leadership. Mediacom joins a growing number of top-tier service providers leveraging Harmonic's cOS platform — making Harmonic a technology partner of choice for eight of the 10 largest cable broadband operators in the
Mediacom is deploying Harmonic's cOS virtualized broadband platform and Ripple modular DAA nodes. By adopting this approach, Mediacom is among the first North American operators to launch DOCSIS 4.0 broadband services leveraging a Unified DOCSIS 4.0 architecture that supports both Full Duplex (FDX) and Frequency Division Duplex (FDD) technologies. The future-ready solution enables Mediacom to significantly enhance the performance and lifespan of its existing DOCSIS infrastructure while maintaining a clear path to fiber evolution. A key differentiator of Harmonic's cOS platform is its innovative PTP-less virtualized core, which allows Mediacom to launch DAA services without a timing network — increasing reliability, simplifying deployments and accelerating the rollout of broadband services.
"Mediacom is leading the charge toward DOCSIS 4.0, and their adoption of our cloud-native broadband software highlights the forward-thinking strategies top operators are embracing to modernize their networks," said Nimrod Ben-Natan, CEO at Harmonic. "Our partnership with Mediacom paves the way for faster DOCSIS 4.0 rollouts, increased operational efficiency and a seamless transition to next-gen broadband."
