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.

Lumentum Unveils New Transceivers to Double Fiber Capacity Across Wide Range of Transmission Distances

  • New 400/800G ZR+ L-band pluggable modules now sampling, enabling expanded fiber capacity for data center interconnect, metro, and long-haul networks
  • Previously announced 800G ZR+ C-band pluggable module now generally available

Lumentum Holdings Inc. ("Lumentum"), a global leader in optical and photonic solutions for the cloud and networking markets, announced today limited sampling of its new 400/800G ZR+ L-band pluggable transceivers, along with general availability of its 800G ZR+ C-band module. Both products will be showcased in live demonstrations at the 2025 Optical Fiber Communications Conference and Exhibition (OFC) at Lumentum Booth #2119 in San Francisco, California, April 1-3.

The new L-band module extends transceiver operation into the L-band spectrum, effectively doubling the usable wavelength range and available fiber capacity. It delivers 800G data rates for data center interconnect (DCI) and metro applications, while supporting 400G data rates in long-haul deployments using quadrature phase shift keying (QPSK) for optimized reach and performance.

The 400G ZR++ L-band module will be demonstrated alongside the TrueFlex® Micro Twin 2x34 integrated C and L Wavelength Selective Switch (WSS), highlighting a comprehensive and cost-effective system-level solution.

“Lumentum brings its proven high-performance optics and integration expertise to the L-band to help customers scale their networks more efficiently,” said Marc Stiller, Lumentum vice president of Product Line Management. “By enabling both 800G and 400G data rates across a broader spectrum, we’re helping to unlock greater capacity on existing fiber infrastructure, supporting the surging demands of AI and cloud-based applications.”

Lumentum’s pluggable modules are designed for direct router-to-router connectivity, reducing overall system complexity and cost. Expanding access to fiber capacity is essential as data traffic driven by artificial intelligence (AI) and machine learning (ML) continues to grow at an unprecedented pace. Both the L-band and C-band modules help address global fiber shortages while enabling the rapid scaling of network transmission capacity.
