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.

Keysight and Nokia Bell Labs Achieve Record Symbol Rate of 260 GBaud Transmission in Coherent Optical Communications

Keysight Technologies, Inc. (NYSE: KEYS), a leading technology company that delivers advanced design and validation solutions to help accelerate innovation to connect and secure the world, and Nokia Bell Labs have successfully tested a 260 GBaud ultra-high-speed optical signal transmission over 100 km of standard single-mode fiber (SSMF) at the European Conference on Optical Communication (ECOC) 2022 in Basel, Switzerland, exceeding the previous record of 220 GBaud.

Artificial intelligence (AI), 5G and internet of things (IoT) applications are driving the demand for more bandwidth. Leveraging high symbol rate systems increases the aggregate per-wavelength information rate to reduce the cost-per-bit in optical systems. A key trend in the telecom industry is the transition to higher symbol rates through integrated optics which reduces the component count, cost and power consumption.

With the mutual goal of improving network performance and efficiency, Nokia Bell Labs and Keysight combined expertise with other research partners to create the record-breaking demonstration of 260 GBaud Dual Polarization Quadrature Phase Shift Keying (DP-QPSK) coherent transmission over 100 km single mode Fiber.

The demonstration consisted of Keysight's new 260 GSa/s arbitrary waveform generator (AWG) (M8199B), which delivers more than 75 GHz bandwidth and a thin-film lithium niobate I/Q modulator with 110 GHz bandwidth. This enables R&D of transmission systems operated with symbol rates up to 260 GBaud and achieving net bitrates greater than 2 Tbit/s in coherent optical communications.

“Keysight is honored to work with Nokia Bell Labs on achieving 260 GBaud,” said Dr. Joachim Peerlings, vice president of Network and Data Center Solutions at Keysight. “The continued proliferation of AI requires new levels of server and network performance that must scale computing resources within reasonable energy bounds. Higher data rates and new modulation formats will be among the enabling technologies for the industry.”

“We achieved this outstanding record of maximum symbol rate of 260 GBaud by leveraging enabling technologies and the expertise of several partners,” said Haïk Mardoyan, Senior Research Scientist, Nokia Bell Labs. “This result is a first milestone to scale long haul data transport systems beyond 2 Tbit/s per wavelength. Improving the energy efficiency of transponders is a permanent challenge for the industry.”
