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.

Comtech’s SLM-5650B Becomes First Sovereign-certified Modem to Operate on SES’s O3b mPOWER MEO Satellite Constellation

Sept. 10, 2025-- Comtech Telecommunications Corp. (NASDAQ: CMTL) (“Comtech” or the “Company”), a global communications technology leader, today announced the company’s market-leading software defined SLM-5650B became the first sovereign-certified modem to receive Government Terminal Certification (“GTC”) to operate on SES’s Medium Earth Orbit (“MEO”) O3b mPOWER satellite constellation.

Operating on the high-throughput low-latency O3b mPOWER system, Comtech’s SLM-5650B will provide critical hybrid communications services to Department of Defense (“DoD”) and coalition customers in some of the world’s most challenging geographies. SES’s certification is unlocking new opportunities for the DoD users that require secure and reliable service and increasingly seeking greater communications sovereignty for critical missions.

“This certification further demonstrates our satellite communications (“SATCOM”) technology leadership, as well as the trust one of the world’s largest satellite owners and space solutions providers, SES, continues to place in Comtech,” said Daniel Gizinski, President of Comtech’s Satellite and Space Communications Segment. “Over 10,000 Comtech defense-grade modems are currently fielded—providing critical connectivity services to DoD and NATO customers today. As one of the leading U.S. manufacturers of sovereign modem technologies, we are thrilled to partner with SES to deliver new capabilities that will help U.S. DoD and coalition warfighters maintain an information advantage across all domains.”

Developed and manufactured at the Company’s corporate headquarters in Chandler, AZ, Comtech’s SLM-5650B is a market leading Wideband Global SATCOM (“WGS”) certified modem designed to deliver critical communications services including government and military applications. The software-defined SLM-5650B currently supports multiple critical DoD and NATO waveforms including STANAG 4486 Ed3 (“EBEM”), Direct Sequence Spread Spectrum (“DSSS”), and DVB-S2X, with the ability to add more waveforms and functions to meet emerging mission needs.

Comtech’s portfolio of defense technologies, including the SLM-5650B, are uniquely designed to deliver capabilities that will enhance Combined Joint All Domain Command and Control operations. Comtech’s expansive portfolio of defense technologies is designed to continuously evolve over time to enable digitalized SATCOM ground network infrastructures needed to maintain a strategic advantage in today’s rapidly evolving threat environment.
