Harmonic has reported a record-breaking demonstration at the recent CableLabs Interop event, setting a new industry benchmark for DOCSIS 4.0 performance. Harmonic’s cOS virtualised broadband platform delivered 14 Gbps of downstream throughput across a multi-vendor network.

“Interoperability testing at CableLabs plays a critical role in accelerating the deployment of DOCSIS technologies by enabling vendors to validate functionality in a collaborative, multi-vendor environment,” said Doug Jones, principal architect at CableLabs. “These intensive sessions — which involve numerous upgrade cycles — are instrumental to advancing modem, RPD and Core interoperability and ensuring readiness for certification. The recent achievement of 14 Gbps downstream DOCSIS throughput across a multi-vendor cable network is a testament to their impact. Continued participation from companies like Harmonic, who have been consistently engaged throughout our DOCSIS 4.0 interop events, supports the broader industry’s ability to deliver reliable, high-speed broadband solutions.”

The interoperability event featured Harmonic’s cOS broadband platform and Pebble-2 DOCSIS 4.0 Remote PHY Device (RPD) delivering 14 Gbps downstream, far surpassing the 10 Gbps DOCSIS 4.0 benchmark target. Harmonic’s cOS platform is the industry’s first solution to unify both modes of DOCSIS 4.0 technology — Full Duplex (FDX) and Frequency Division Duplex (FDD), giving operators the flexibility to choose the deployment strategy that best matches their business and network needs.

“This major milestone demonstrates that our cOS platform is primed to support DOCSIS 4.0 rollouts, enabling the standard’s full set of downstream and upstream speed options with fiber-like symmetric multigigabit speeds,” added Asaf Matatyaou, senior vice president, product, at Harmonic. “Harmonic continues to push the boundaries of what’s possible through innovation and collaboration to lead the broadband industry’s transformation and shape the future of connectivity.”

Harmonic’s cOS platform powers next-gen broadband services through more than 33 million customer premises equipment (CPE) devices worldwide for operators in North America, Europe, Latin America and Asia.
