Versatile broadband solutions for FTTx

Harmonic fiber-to-the-x (FTTx) solutions power the ability to deliver broadband service excellence and win the race for more subscribers. Integrating our Emmy Award-winning cOS (formerly CableOS®) virtualized core software and a comprehensive portfolio of network edge devices, the solutions provide high-speed connectivity, accelerated deployment timelines, superior network performance and unparalleled service reliability. 

The cOS platform is the smart choice for operators who are either looking to upgrade their existing DOCSIS network to 10G, or for those with existing fiber networks that want to add new capabilities, extend service reach and enhance subscriber quality of experience. High-speed broadband services can be delivered over both fiber and HFC DOCSIS infrastructure using a variety of deployment technologies, including passive optical network (PON) and optical line termination (OLT) devices.


One platform for Fiber & DOCSIS

The cOS platform supports multiple broadband access technologies, including XGS-PON, EPON and COMBO-PON, as well as DOCSIS 3.1 and 4.0. By converging fiber and DOCSIS capabilities on a single platform, operators can simultaneously support both OLT and Remote PHY devices (RPDs), enabling the launch of 10G fiber services over existing coax networks.


Standards-based interoperability

The cloud-native cOS core software controls connected devices to consolidate management of network assets, including third-party optical network terminals (ONTs) and optical network units (ONUs). This interoperability eases the ability to align equipment purchases with business and network requirements, whether related to pricing, technical considerations or subscriber experience.


Designed to generate savings

The cOS software eliminates hardware from headend and hub sites to significantly reduce space, power and cooling costs while increasing network capacity. Additional savings are realized by serving customers from high-density hardened shelves in outdoor cabinets and high-density hardened nodes, both of which require minimal construction and maintenance.


Your path to 10G starts
with the market-leading cOS platform

Power high-bandwidth, reliable broadband services to win customers and reduce churn.

Multi-tenancy & feature velocity

The cOS software platform hosts multiple virtualized applications — including vCMTS, vBNG and vOLT — and enables hitless software upgrades for more frequent and seamless system updates to provide an always-on service experience for subscribers.

Flexible compute & cloud edge

Our software-based approach provides a flexible compute architecture to better manage changing bandwidth and capacity demands. By unlocking the power of the cloud, you can also move network functions closer to the edge.

Simplified network evolution

The cloud-native cOS broadband platform provides unparalleled scalability and upgradeability. Legacy third-party nodes can even be upgraded in the field to ease network evolution to distributed access architecture (DAA) and PON technologies.

Extended service reach

The cOS FTTx solution’s use of long-range coherent optics enables the delivery of multi-gigabit, enterprise-class connectivity across thousands of kilometers of middle-mile network, making it much easier to reach subscribers in underserved and rural areas.

Always-on service availability

Harmonic's cOS Central solution continuously monitors and reports on network performance. Integrated AI utilizes this data to provide insight into system-wide activity, helping to achieve 99.999% service availability of cOS fiber solutions.
