Offer multi-gigabit broadband with real versatility

Benefit from greater agility, scalability and interoperability to improve your total cost of ownership as you advance on the path to 10G broadband. Ease your network evolution with greater optionality to support multiple access architectures.

DOCSIS 4.0 and the Flexible Mac Architecture (FMA) leverage distributed architectures to handle shifts in network traffic. You'll improve service quality and transition into a new era of ultra-connectivity. 

Common orchestration with MAC anywhere

Deploy a truly cloud-native solution to transition to FMA and prepare for DOCSIS 4.0 in alignment with the 10G initiative. The CableOS® Cloud-Native Core Platform is a virtualized solution to support multiple access technologies.

Rollout new services with the speed of software

CableOS in an FMA gives you the option to deploy the MAC in the node, hub site, headend, or data center. You increase service velocity as CableOS dynamically orchestrates MAC anywhere across the network to deliver a superior quality of service to your subscribers.

Sustainably expand connectivity & capacity

With third-party interoperability, CableOS supports both R-PHY and R-MAC-PHY providing a common framework, regardless of the DOCSIS revision. Fully benefit from true virtualization to extend beyond DAA and add PON and mobile services to existing DOCSIS services.

CableOS: The foundation for DOCSIS 4.0 & FMA

The Flexible MAC Architecture (FMA) unlocks the power of true virtualization with Harmonic's market-leading CableOS® Platform and our groundbreaking MAC Anywhere capability.

You can combine and orchestrate Remote-PHY (R-PHY) and Remote MAC-PHY (R-MAC-PHY) using a single, containerized, and flexible DOCSIS MAC solution based on your Distributed Access Architecture (DAA). Leverage the MAC Anywhere ecosystem and deploy CableOS in any third-party DAA edge device. With our cloud-native software and true virtualization, you enable greater flexibility and scalability for your broadband network.

Green & lean

Save on power and space by up to 75% with up to 90% decrease in facilities. Leverage high-performance common off-the-shelf (COTS) coupled with DAA Node technology to eliminate legacy hardware in your headend and hub sites.

Flexible compute

Get a flexible compute architecture to unburden your network from heavy traffic loads, optimize resources and unlock the power of the cloud for edge compute. Give your network the power to transform with efficiency.


Our multi-access, cloud-native broadband platform hosts multiple applications including virtualized cable modem termination system (vCMTS), virtualized optical line terminal (vOLT) and virtualized broadband network gateway (vBNG), to enable zero-touch provisioning and a low latency DOCSIS (LLD) application.

The products that make FMA possible
