Nortech Systems Launches Power over Fiber Technology Platform for EMI-Sensitive Applications

Minneapolis, Minnesota, April 07, 2026 (GLOBE NEWSWIRE) -- Nortech Systems Incorporated, a leading provider of design and manufacturing solutions for complex electromedical devices and electromechanical systems, has announced the launch of its Power over Fiber technology platform. Power over Fiber addresses a critical engineering challenge by delivering reliable power and data through optical fiber cable, eliminating the need for a separate local power source. Using optical fiber instead of copper, the platform removes electrical noise and ground loops while providing electromagnetic interference ("EMI") immunity, electrical isolation, and a lighter, more sustainable solution for long-distance power delivery across mission-critical applications, such as power transmission in medical, aerospace, low-orbit, subsea, defense and industrial applications.

"Our Power over Fiber platform solves a fundamental engineering challenge for EMI-sensitive environments," said Jay D. Miller, CEO of Nortech Systems. "By transmitting power safely through optical fiber, we eliminate electrical noise and provide a secure, lightweight power solution for medical imaging, aerospace, and defense applications. This innovation directly reflects our commitment to engineering advanced, highly reliable technologies that drive mission-critical industries forward."

The technology offers four core advantages over conventional copper power solutions: EMI immunity and shielding, full electrical isolation, a reduced overall cable footprint, and the ability to deliver power over longer distances to remote optical components.

The Power over Fiber platform is suited to a broad range of demanding use cases. In medical settings, Power over Fiber supports diagnostic imaging systems, including MRI, as well as surgical environments where minimizing EMI is critical to patient safety and device performance. In aerospace and defense, Power over Fiber is well-suited for satellites, aircraft, and military hardware. Underwater and subsea deployments also benefit from the platform, as optical fiber is lighter and more corrosion-resistant than copper in those environments. Industrial automation applications — including robotics and high-voltage factory environments — can use Power over Fiber to power remote actuators, cameras, and controllers without introducing electrical noise.

By removing the dependency on copper for power delivery, Nortech's Power over Fiber platform also offers a more sustainable and space-efficient solution for engineers working within tight design constraints, including embedded systems, lighting, machine vision and motor control applications. This launch reflects Nortech's continued investment to help customers solve their most complex challenges with fiber optic innovation, building on the Company's established capabilities in complex cable and harness assemblies, printed circuit board assemblies, and system-level integration.
