Harmonic Showcases Vendor-Agnostic Intelligence and Versatile Fiber Portfolio at Network X 2026

Latest Innovations Extend Fiber to Any Location and Elevate Subscriber Quality of Experience

SAN JOSE, Calif., Oct. 8, 2026 /PRNewswire/ -- Harmonic (NASDAQ: HLIT) will showcase its latest fiber broadband innovations at Network X 2026 that help operators take fiber to more locations, operate more intelligently and manage multi-vendor fiber ecosystems. Harmonic's fiber portfolio includes a versatile range of OLT form factors for high-density and remote deployments, running on the company's cOS™ software. Combined with cOS SensAI™, Recon and cOS Loop™, the portfolio enables operators to deploy fiber faster, resolve network issues sooner and deliver a consistently high-quality subscriber experience.

"Operators want to build fiber without breaking the business case, and run it with confidence once it's live," said Stefan Meier, Vice President of Sales, Europe, at Harmonic. "At Network X we will show an expanding fiber portfolio backed by a growing number of third-party interoperated ONTs. With Harmonic solutions, operators broaden their fiber options from dense urban deployments to remote sites and leverage an intelligence layer that works across every vendor in the network. Our goal is to help operators accelerate business growth and deliver an experience that keeps subscribers loyal."

Flexible Fiber Reach to Anywhere
At Network X, Harmonic will display a versatile fiber portfolio, including the Pier-2 50G PON OLT shelf, Oyster+ node housing, Pearl-1XL R-OLT and Fin SFP-based OLT family. Harmonic's fiber solutions offer varied deployment options to address operators' unique density and reach requirements while simultaneously managing space, power and cooling needs. Additionally, Harmonic's Open ONT approach gives operators the flexibility to choose customer premises equipment that best fits their network requirements, eliminating vendor lock-in and driving down costs.

A Shift from Reactive Firefighting to Proactive Network Operations
Harmonic will show its new cOS SensAI vendor-agnostic intelligence fabric to attendees at Network X. SensAI gathers data from disparate network and operational systems into a coherent information layer and correlates signals across systems to explain diagnoses and suggest remediation. The intelligence fabric helps service providers proactively manage fiber network operations, raise NPS, improve subscriber experience and build long-term customer loyalty.

Faster, Smarter Monitoring to Reduce Outages and Speed Up Repairs
Harmonic's new Recon family of network monitoring and measurement solutions helps operators detect physical fiber issues faster and locate them precisely. Recon pairs in-network monitoring hardware and handheld diagnostic tools with cloud-based software to provide real-time visibility across fiber infrastructure. The solution integrates with Harmonic's cOS SensAI intelligence fabric, helping teams locate and repair network problems sooner.

Accelerated Fiber Expansion with Multi-Vendor PON Management
At Network X, Harmonic will also highlight its new cOS Loop management capability to automate provisioning and simplify remote diagnostics and subscriber management across multi-vendor PON networks. cOS Loop enables operators to accelerate fiber expansion by leveraging multi-vendor systems without the complexities of managing disparate solutions.

Harmonic will showcase its latest fiber broadband innovations at Network X 2026 in Vienna, Oct. 13-15 in booth L71. To set up a meeting with Harmonic at the event, visit www.harmonicinc.com/events/network-x.
