Armstrong has launched a dual-path network evolution, deploying pure fiber-to-the-home alongside a transition to virtualized Distributed Access Architecture for its existing hybrid fiber-coaxial network. This strategy is designed to balance infrastructure modernization with the specific requirements of its current service areas.
Why it matters
The transition aims to improve competitive standing against national cable and telecommunications operators while addressing the growing subscriber demand for symmetrical or higher-capacity upload speeds. By modularizing its network hubs, the company seeks to manage both physical footprint and energy costs.
Armstrong now offers a 3 Gbps service tier powered by XGS-PON—a 10-gigabit symmetric passive optical network technology—compared to its 1 Gbps standard maximum. The HFC network upgrade replaces legacy hardware with a virtualized software-based platform to improve operational efficiency.
The players
Armstrong
A broadband provider currently migrating its infrastructure to support higher speeds through fiber and virtualized cable systems.
Harmonic
A technology firm providing the cOS Broadband Platform and virtualized software used for Distributed Access Architecture upgrades.
Adtran
A network hardware supplier providing the fiber-to-the-home technology required for the company's suburban and rural deployments.
The details
The strategy employs a dual-infrastructure approach: pure fiber-to-the-home for new deployments and Distributed Access Architecture (DAA) for existing hybrid fiber-coaxial (HFC) networks. The DAA process replaces legacy Cable Modem Termination Systems (CMTS) with virtualized software, which removes the need for certain physical equipment at the network hub. This allows the company to upgrade its service delivery one network hub at a time, moving away from centralized hardware toward a more flexible, software-defined architecture.
Timeline
The company is evaluating its long-term network migration strategy over the next 3-5 years.
The Tech Race
Armstrong's shift aligns with the broader industry trend of adopting virtualized software to extend the capacity of existing HFC assets. This move positions the firm against national cable providers that are simultaneously scaling XGS-PON and DAA to maintain competitive broadband throughput.
Subscribers in serviced areas can expect access to higher tiers, specifically the 3 Gbps service enabled by the new XGS-PON architecture. Availability of these faster tiers remains contingent on the company's ongoing hub-by-hub upgrade cycle scheduled over the next several years.
The takeaway
Armstrong is betting on a dual-path approach to solve the challenge of maintaining competitive speeds while transitioning away from legacy hardware. Watch for further announcements on the company's service rollout progress as they complete their multi-year migration plan.
