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 Coherent (COHR) Stock Is Down Today

COHR Cover Image

What Happened?

Shares of materials and photonics company Coherent (NYSE: COHR) fell 3.5% in the afternoon session after new export controls on critical minerals from China raised investor concerns about the stability of the company's global technology supply chain. 

The move by China created worries about potential risks to Coherent's production continuity, as the company has significant exposure to Chinese supply chains. Adding to the negative sentiment, the Pomerantz Law Firm announced it was investigating claims on behalf of investors concerning whether the company had engaged in unlawful business practices. These headwinds appeared to overshadow positive news, as Rosenblatt analyst Mike Genovese maintained a 'Buy' rating on the stock and raised the price target from $135 to $150.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks. Is now the time to buy Coherent? Access our full analysis report here.

What Is The Market Telling Us

Coherent’s shares are extremely volatile and have had 41 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was 4 days ago when the stock dropped 6.8% as worries over worsening trade relations with China were triggered by critical comments from President Donald Trump. Trump targeted China's tightening controls on rare earth metals, which are vital components in many technology products from electric vehicles to defense systems. The president's tone and the suggestion of canceling a meeting with President Xi caused a rapid sell-off in the market. 

Earlier in the week, China announced new export controls on the critical minerals. Beijing's Commerce Ministry stated that foreign suppliers now need government approval to export products containing certain rare-earth materials. These materials are essential for producing high-tech goods, including computer chips, electric vehicles, and defense technology. Analysts viewed the move as a strategic assertion of China's dominance in the global rare earth supply chain, particularly amid ongoing trade tensions and ahead of an anticipated meeting between the US and Chinese presidents. 

Consequently, technology stocks with significant exposure to Chinese supply chains, such as Nvidia and AMD, experienced sharp declines. This downturn was exacerbated by the bearish sentiment surrounding a prolonged U.S. government shutdown, adding to overall market uncertainty.

Coherent is up 11.3% since the beginning of the year, and at $112.39 per share, it is trading close to its 52-week high of $122.35 from October 2025. Investors who bought $1,000 worth of Coherent’s shares 5 years ago would now be looking at an investment worth $2,492.

Today’s young investors won’t have read the timeless lessons in Gorilla Game: Picking Winners In High Technology because it was written more than 20 years ago when Microsoft and Apple were first establishing their supremacy. But if we apply the same principles, then enterprise software stocks leveraging their own generative AI capabilities may well be the Gorillas of the future. So, in that spirit, we are excited to present our Special Free Report on a profitable, fast-growing enterprise software stock that is already riding the automation wave and looking to catch the generative AI next.
