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.

List of top impact investing fund managers shows growing scope and scale of the field

List of top impact investing fund managers shows growing scope and scale of the field

A new list of the top impact investing fund managers highlights the strides being made in the field, particularly the number of managers with $1 billion or more under management,  making them institutional size.

The ImpactAssets 50 2025, a guide to impact investment fund managers globally, features 165 experienced and emerging impact investment fund managers, the highest number in the survey’s 14-year history. The IA 50 offers investors a curated and publicly accessible database to explore the industry’s leaders across the full range of investment types.

“As impact investing continues its march into the financial mainstream, the IA 50 has become a powerful barometer of industry maturation and the most respected recognition in our sector,” Margret Trilli, CEO and CIO of ImpactAssets, said in a press release. “The scale, growth and credibility of this year’s IA 50 managers demonstrate that impact investing is not only thriving, it is becoming an undeniable force in the market.”

Total assets under management of IA 50 firms surged to $130.6 billion, representing a 35% year-over-year increase, driven by the inclusion of new, large impact managers as well as the steady growth of established firms, the survey found.

In the 2025 Emerging Impact Manager category 21 managers were listed who focus on climate as their primary impact theme, the largest number ever in the category and a category total that has nearly doubled since 2021. This year’s EIM category also saw a resurgence of infrastructure-focused managers with three such managers selected, signaling the highest-ever infrastructure focus on the EIM list.

All told, 50 impact investing fund managers were selected for this year’s core IA 50 list, 65 managers for the Emerging Impact Manager list and 50 managers for the Emeritus list.

Key impact trends from the IA 50 2025

  • Growing manager AUM: A total of 24 IA 50 managers have reached institutional scale, with $1 billion or more in AUM, a 33% increase over the two previous years.
  • Financial returns and impact work in tandem: 46% of managers on the list target market-rate returns, while 28% pursue above-market returns. The core IA 50 list is predominantly market-rate (36%) and above-market (28%) managers.
  • Climate and social impact priorities: 50% of listed managers primarily focus on social themes such as financial inclusion and community development, while 33% prioritize climate-related investments, including clean tech, alternative energy and decarbonization.
  • Beneficiaries of impact capital: The majority of IA 50 managers focus on supporting small businesses, rural communities, low income and disadvantaged communities.
  • Third-party impact verification on the rise: 28% of core IA 50 managers and 24% of Emeritus managers have impact reports verified by third-party assessors, marking a steady progression in impact transparency.

“This year’s IA 50 showcases how impact investing is quickly coming of age – not only in scale and financial sophistication, but also in accountability and rigor,” said Jed Emerson, IA 50 Review Committee chair. “The increasing prevalence of third-party impact verification, larger institutional-scale fund sizes, and record-breaking newer entrants signal a maturing market that remains deeply committed to driving positive change.”

Unlike lists based purely on AUM rankings or editorial selection, the IA 50 blends quantitative analysis with expert qualitative review to identify managers that are not only financially sound, but also deeply committed to measurable impact.

“The IA 50 not only reflects where impact investing is today, but also provides a roadmap for its future,” said Rehana Nathoo, Founder and CEO at Spectrum Impact and an IA 50 Review Committee member. “The rigorous selection process and expert review that define the IA 50 reinforce its position as the industry’s gold standard – giving investors confidence that the firms featured are at the forefront of driving meaningful impact.”
