power over fiber technical

"has announced the launch of its Power over Fiber technology platform."

Power over fiber is a way to deliver electrical power using pulses of light sent through optical fiber, with a small device at the far end converting that light back into electricity. For investors, it matters because it enables safe, lightweight, and interference-free power delivery to remote, sensitive or hazardous equipment—like wiring a lamp with a fiber-optic cable instead of copper—opening markets in telecom, industrial automation, defense, and certain Internet-of-Things applications.

optical fiber technical

"delivering reliable power and data through optical fiber cable, eliminating the need"

A long, thin strand of glass or plastic that carries data as pulses of light, like a clear pipe that moves water very quickly but with tiny loss. Investors care because optical fiber is the backbone of high-speed internet, cloud services and telecom networks; deploying or owning fiber can drive steady revenue, large upfront costs and long-term growth as demand for faster, higher-capacity data transport rises.

electromagnetic interference technical

"providing electromagnetic interference (“EMI”) immunity, electrical isolation, and a lighter"

Electromagnetic interference is unwanted electric or magnetic energy that disrupts the normal operation of electronic devices, like static on a radio or someone speaking over a phone call. It matters to investors because interference can reduce product reliability, trigger regulatory testing or recalls, raise development and compliance costs, and hurt sales or reputation—any of which can affect a company’s revenue and risk profile.

emi technical

"providing electromagnetic interference (“EMI”) immunity, electrical isolation, and a lighter"

An EMI is a UK tax-advantaged employee share option plan that lets a company grant executives and staff the right to buy shares at a preset price after a vesting period. It matters to investors because it aligns employees’ incentives with company performance—like giving key workers a stake in the business—while potentially diluting existing shareholders and changing future earnings per share when options are exercised.

electrical isolation technical

"providing electromagnetic interference (“EMI”) immunity, electrical isolation, and a lighter"

Electrical isolation is the deliberate separation of one electrical circuit or component from another so that electricity cannot flow between them, like putting an insulating wall between two rooms to stop water from leaking. It matters to investors because isolation reduces the risk of shocks, fires or device malfunction, affects product safety certifications and compliance costs, and can influence manufacturing complexity, warranty exposure and market acceptance of electronic or medical products.

mission-critical technical

"solution for long-distance power delivery across mission-critical applications, such as power"

An asset, system, product, service or process labeled mission-critical is essential to an organization’s core operations — if it fails or is interrupted, the business would suffer major financial, legal or reputational harm. Investors care because mission-critical items often drive most of a company’s revenue or regulatory standing, concentrate risk, and require extra spending on maintenance, backups and oversight; think of them as the engine in a car or the heart in a body whose performance and reliability determine the company’s health.

printed circuit board assemblies technical

"capabilities in complex cable and harness assemblies, printed circuit board assemblies, and"

Printed circuit board assemblies are boards that hold and connect electronic parts—like chips, resistors and connectors—so a device’s electrical signals flow where they need to. Think of them as the backbone and wiring harness of electronic products. Investors care because PCB assemblies determine product performance, manufacturing cost and supply-chain risk, so changes in their availability, quality or price can affect a company’s revenue, margins and delivery schedules.

system-level integration technical

"printed circuit board assemblies, and system-level integration."

System-level integration means combining multiple parts or subsystems so they work together as a single, functioning product or service—like fitting engine, electronics and software into a car so it drives reliably. For investors it matters because successful integration reduces technical risk, development time and ongoing costs, improves performance and customer adoption, and therefore affects a company’s ability to reach revenue targets and control expenses.

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.
