neu-medianet Fast-Tracks Fiber Broadband Rollout with Harmonic

SAN JOSE, Calif., Sept. 23, 2025 /PRNewswire/ -- Harmonic (NASDAQ: HLIT) today announced that German broadband operator neu-medianet is making the leap to XGS-PON fiber broadband services with Harmonic's industry-leading cOS™ virtualized broadband platform. The cOS platform enables neu-medianet to overbuild its existing network and augment its DOCSIS footprint with XGS-PON for delivering symmetric multi-gigabit broadband services. Leveraging Harmonic's solutions, neu-medianet is building a future-ready broadband infrastructure to cost-effectively deliver a range of reliable, high-speed broadband services and grow its subscriber base.

"Expanding our fiber broadband network is central to our long-term strategy of evolving and growing our business," said Steffen Raatz, CTO of neu-medianet. "Deploying Harmonic's cOS platform gives us the flexibility and scalability we need to deliver exceptional-quality fiber and DOCSIS broadband services to our customers."

neu-medianet is deploying Harmonic's cOS platform with high-density, energy-efficient Pier optical line terminal (OLT) shelves that minimize infrastructure requirements and simplify the rollout of fiber services. Furthermore, Harmonic's Open ONT approach empowers neu-medianet to eliminate vendor lock-in and select customer premises equipment (CPE) devices that best fit its needs — accelerating service velocity and reducing total cost of ownership.

"neu-medianet is taking a pivotal step forward by embracing future-ready technologies that position them as a forward-thinking fiber broadband provider in Germany," said Stefan Meier, vice president of broadband sales Europe at Harmonic. "We're proud to support their vision with a virtualized broadband platform that reduces deployment complexity to meet growing subscriber demands."

Harmonic's local partner Normann Engineering is supplying the components and providing system integration support, ensuring smooth deployment.

Harmonic's market-leading 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. 

Harmonic will showcase its cOS virtualized broadband platform at Connected Britain, Sept. 24-25 in London, in booth 153.
