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.

AM Best Places Credit Ratings of Sompo Seguros Mexico S.A. de C.V. Under Review With Positive Implications

AM Best has placed under review with positive implications the Financial Strength Rating of A+ (Superior), the Long-Term Issuer Credit Rating of “aa-” (Superior) and the Mexico National Scale Rating of “aaa.MX” (Exceptional) of Sompo Seguros Mexico, S.A. de C.V. (Sompo Mexico) (Mexico City, Mexico).

Sompo Mexico is a subsidiary of Sompo America Insurance Company (SAIC) and a member of Sompo International Holdings Ltd. (SIH). Sompo Japan Insurance Inc. (SJ) is the core operating unit of SOMPO Holdings, Inc. (SOMPO Holdings), the ultimate parent and one of the largest non-life insurance groups in Japan. Sompo Mexico is well-integrated into the group.

The ratings reflect SJ’s balance sheet strength on a consolidated basis, which AM Best assesses as strongest, as well as its strong operating performance, favorable business profile and appropriate enterprise risk management (ERM).

The ratings recognize Sompo Mexico’s integration and support from SIH and SJ, through SAIC, which provides synergies and operating efficiencies to the Mexico subsidiary. Sompo Mexico maintains the strongest level of risk-adjusted capitalization, as measured by Best’s Capital Adequacy Ratio (BCAR).

These Credit Rating (rating) actions follow the announcement on 27 August 2025, that SOMPO Holdings, Inc., via a wholly owned subsidiary of SIH, has entered into a definitive merger agreement to acquire 100% of the issued Class A ordinary shares of Aspen Insurance Holdings Limited (Aspen) for approximately USD 3.5 billion in an all-cash transaction. Upon completion, Aspen will become a subsidiary of SIH, the intermediate holding company under SJ.

The under review with positive implications status reflects the potential material benefits in Sompo group’s business profile following the acquisition of Aspen, which could accelerate the geographic diversification and lead to a significant enhancement in its presence in the global property/casualty (re)insurance market. Aspen is a global (re)insurance player with a diversified underwriting portfolio and expertise in specialty lines.

The transaction is anticipated to close in the first half of 2026, subject to regulatory approvals. The ratings will remain under review with positive implications pending the completion of the transaction and until AM Best can evaluate fully the impact on SJ’s rating fundamentals.
