Harmonic

Harmonic is an American video and broadband technology company, founded in 1988 as Harmonic Lightwaves and headquartered in San Jose, California. It builds video routing, server and storage systems for broadcast and internet video, along with cable edge equipment that delivers broadcast and on-demand services, supplying operators such as Comcast, Charter Communications and Virgin Media, before selling its video business to MediaKind in 2026 to focus on broadband technology. Tech-Star supplies new and refurbished Harmonic hardware including AC power supply modules for the NSG 9000 cable and broadband video edge platform. Refurbished NSG 9000 power modules remain in demand because operators keep this edge equipment running for years, and a failed supply unit has to be replaced with the matching module rather than a redesign.
