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.

How XRP holders can earn daily passive income through OPTO Miner

By: Zexprwire

London, UK, 18th August 2025, ZEX PR WIRE, In the face of increasingly volatile cryptocurrency markets, many investors are beginning to rethink the “proactivity” and “stability” of their assets. OPTO Miner, Europe’s leading cloud computing power platform, has recently quietly launched several high-yield new contracts, with main cryptocurrencies including XRP/BTC/DOGE/LTC, offering a maximum daily return of up to 700 XRP, sparking significant attention within the mining community.

It’s not just about attractive returns; it’s a testament to a mature strategy.

Unlike the speculative “bet on price fluctuations” model prevalent in the cryptocurrency space, the new contract offered by OPTO Miner reflects a deep understanding and strategic positioning of the long-term value of cloud mining.

“We have observed that an increasing number of users are no longer satisfied with simply ‘holding coins and waiting,’ but instead seek assets that actively generate value daily,” said the product manager of OPTO Miner in an interview. “Currencies like XRP, BTC, DOGE, and LTC inherently possess high transaction efficiency and widespread payment applications. Combined with our backend energy efficiency optimizations, this contract achieves unprecedented stability and output rates.”

It is worth mentioning that OPTO Miner was founded in London, UK in 2018. This year, it launched a mobile app, allowing users to remotely view their earnings, adjust contract settings, or withdraw coins using only their mobile phones. No longer restricted by equipment, mining has truly become “anytime, anywhere.”

Currently, more than 7 million registered users have chosen OPTO’s new contracts. Platform data shows that the contracts are flexible, with varying lengths, allowing users to choose for themselves.

Conclusion: Don’t wait for the “next bull market”—create your own gains every day.

In the past, the growth of digital assets often depended on external market conditions. However, platforms like OPTO Miner are now empowering users to take control of their own pace, lock in stable returns through contracts, and leverage technology to drive wealth growth.

The value of XRP may not lie in overnight surges but in steady, daily returns.

In this fast-paced era, perhaps the truly wise choice is to let your assets work for you every day.
