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.

Canon Announces EOS R6 Mark II, RF 135mm f/1.8 Lens, and Speedlite EL-5; First Look and More Information at B&H

Photography News: Canon has just revealed the upgraded EOS R6 Mark II Mirrorless Camera, a premium RF 135mm f/1.8 L lens, and mid-range Speedlite EL-5.

B&H is excited to announce the Canon EOS R6 Mark II Mirrorless Camera, RF 135mm f/1.8 L IS USM Lens, and Speedlite EL-5.

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20221101006438/en/

It’s hard to believe that the R6 came out over two years ago. As time continues to fly and the speed with which technology improves never seems to slow, we are fortunate to be getting a Canon R6 Mark II of this excellent camera already.

Key Features:

  • 24.2MP full-frame CMOS sensor
  • Full-width oversampled 4K 60p video recording
  • External 6K raw video and internal 4K with oversampling from 6K area
  • Canon Log 3
  • 80% faster AF system
  • AF with deep learning technology for subject detection, including human, animal, vehicle, horses, trains, and airplanes
  • Movie recording that exceeds 30 minutes
  • Up to 12 fps shooting with mechanical shutter and 40 fps with electronic shutter
  • In-body image stabilization rated to 8 stops
  • Multi-function shoe

It may not look dramatically different, but it does get some key tweaks. The locking method on top dials should result in fewer accidental adjustments during operation. This camera is going to be a great pick for advanced amateurs.

Stills have gotten a speed boost with burst shooting up to 40 fps with the electronic shutter. Dual Pixel RAW has been unlocked for ultimate flexibility in post. The autofocus is one of the bigger updates with up to 80% faster performance. The deep learning algorithm can now recognize even more subject types. One can now lock on to humans, animals, horses, vehicles, trains, airplanes, and plenty more.

Video gets some nice updates with the ability to record in 4K up to 60p without any crop. Plus, the Canon R6 Mark II camera can output 6K raw video over HDMI to a compatible recorder, such as the Atomos Ninja V+, to record in ProRes RAW. The multi-function shoe expands functionality for extra accessories, including XLR adapters, microphones, and more.

We aren’t hurting for a premium portrait optic for R Series cameras (thanks to the 85mm f/1.2 L and its DS sibling), but it never hurts to get something nearly as fast and just a tad longer. That’s where the Canon RF 135mm f/1.8 L IS USM sits. Primed to be the portrait prime for Canon shooters, the fast 135mm lens will create stunning images with a flattering perspective and exceptionally shallow depth of field.

Key Features

  • RF-Mount Lens/Full-Frame Format
  • Aperture Range: f/1.8 to f/22
  • Nano USM AF System
  • Optical Image Stabilizer
  • Ultra-Low Dispersion Elements
  • Air Sphere Coating
  • Lens Function Buttons and Control Ring
  • Rounded 9-Blade Diaphragm

It should go without question that this 135mm is meant to be a premium choice with sharp glass and minimal aberrations—it is an L Series lens after all. Canon has been going for it with its mirrorless systems and we are seeing a built-in Image Stabilizer, a rarity in a lens of this type. It should make handheld use much easier.

The lens's exterior has all the marking of an L-Series optic. There is also a function button available for quick access to your most used tools.

Not exactly the most exciting segment, on-camera flashes serve an important role in many photographers’ bags. Here comes the Speedlite EL-5, a new mid-range option for Canon systems. The relatively compact size, especially compared to the flagship EL-1, should make it a solid everyday pick for slimmer mirrorless cameras. This is also the first flash unit that features the new multi-function shoe found on the EOS R6 Mark II, EOS R3, EOS R7, and EOS R10.
