AI is moving from the data center into the home, and the access network has to keep up with more upstream traffic, lower latency, and higher reliability expectations. Operators have to meet those expectations without growing operating cost. Harmonic built the platform that did this for cable and extends it to fiber, to network intelligence, and to the edge.
The broadband platform
for the AI era.
Harmonic connects the network, makes it intelligent, and turns the edge into compute, all on one software platform: cOS.
Deliver broadband over any wire
Simplify network convergence
Any density, distance and location
AI is coming home. Your network has to be ready.
Connectivity: One platform for every access network
DOCSIS, fiber, and what comes next, running on the same cOS software.
Operators shouldn't have to choose between cable and fiber. cOS runs DOCSIS and PON side by side, so subscribers can move from HFC to fiber with a software configuration, not a rebuild. Speeds, latency, and new capabilities arrive as software upgrades instead of hardware cycles.

650,000+ homes upgraded to multi-gig symmetrical service.

Migrating its HFC footprint to fiber on the existing platform.

Overbuilding HFC with fiber using the same architecture.

Intelligence: Fewer truck rolls. Fewer churned customers. Same operating budget.
Reliability, not speed, is what wins in a hyper-competitive market. SensAI collects telemetry from the back office to the customer's home, builds a network graph that gives it context, and puts a team of seven specialized AI agents to work around the clock. It plugs into the tools operators already use, so teams get smarter without learning another UI.

Amply
Amplifier management that works with any protocol or format.
Beacon
A speed maximizer that watches every modem and reacts to its performance at the edge.

SensAI opened hundreds of field tickets and prioritized them down to a few dozen truck dispatches.

(100% non-Harmonic PON network): Found a video degradation caused by a CDN configuration, which would otherwise have taken weeks or months to trace.
Compute: Turn freed-up facilities into the AI edge.
cOS Edge AI orchestrates low-latency inference from the thousands of sites already running cOS.
Network modernization collapses racks of legacy equipment into a fraction of the space, leaving powered, fiber-connected facilities milliseconds from customers and businesses. cOS is already an edge compute platform running containers on Kubernetes, which makes it a natural orchestration layer for GPU capacity at the edge.
