About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Why Is Power Integrations (POWI) Stock Soaring Today

POWI Cover Image

What Happened?

Shares of semiconductor designer Power Integrations (NASDAQ: POWI) jumped 20.2% in the afternoon session after the company detailed its collaboration with NVIDIA to advance its PowiGaN gallium-nitride technology for next-generation AI data centers. The partnership aimed to accelerate the transition to more powerful 800 VDC systems designed for megawatt-scale computer racks that power artificial intelligence. Power Integrations published a white paper at the 2025 OCP Global Summit explaining the benefits of its technology. According to the company, its new chips delivered greater power density and efficiency compared to competing devices. The announcement was significant as the demand for power in AI data centers has been rising rapidly, and this technology helped address that need by simplifying rack design and making more efficient use of space.

After the initial pop the shares cooled down and closed the day at $43.18, up 24.7% from previous close.

What Is The Market Telling Us

Power Integrations’s shares are very volatile and have had 20 moves greater than 5% over the last year. But moves this big are rare even for Power Integrations and indicate this news significantly impacted the market’s perception of the business.

The previous big move we wrote about was 3 days ago when the stock dropped 5.9% on the news that President Donald Trump threatened to impose 'massive' new tariffs on Chinese goods. President Donald Trump's threat of "massive" new tariffs on Chinese goods sent shockwaves through the market, directly impacting chipmakers like Nvidia and AMD. Trump noted China's tightening controls on rare earth metals, which are vital components in many technology products from electric vehicles to defense systems. Compounding the pressure, Beijing has reportedly initiated its own countermeasures. These include tightening export controls on crucial raw materials such as rare earths and launching an antimonopoly investigation into chip giant Qualcomm. 

Furthermore, reports indicate that Chinese customs officials are now conducting stringent checks on semiconductor shipments arriving at ports, specifically targeting certain high-end chips. This escalating back-and-forth creates significant uncertainty for the semiconductor industry, which relies heavily on complex global supply chains and access to international markets, leading to a broad sell-off across the sector.

Power Integrations is down 25.9% since the beginning of the year, and at $45 per share, it is trading 33.9% below its 52-week high of $68.05 from November 2024. Investors who bought $1,000 worth of Power Integrations’s shares 5 years ago would now be looking at an investment worth $731.71.
