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.

The List of Fish With the Most Omega-3 is Released

By: MerxWire

We often hear people say that eating fish will make you smarter. Fish is rich in omega-3 fatty acids, protein, vitamins, and minerals, which benefit human health. Among them, mackerel, salmon, and sardines have the highest Omega-3 content, and eating them once a week is recommended.

London, UK (Merxwire) – Fish is rich in vitamins, minerals, and omega-3 fats. It is also one of the sources of high-quality protein intake for the human body. But with so many types of fish, which fish is the best, and how much should we eat? Don’t worry; according to the British National Health Service (National Health Service, NHS), it is recommended that adults consume at least two servings of fish a week (one serving is about 140 grams), and one serving should preferably be oily fish.

Edible fish can be divided into white fish and oily fish according to the level of fat content. White-fleshed fish have white, low-fat flesh like cod and grouper; oily fish have darker, fatty meat, like mackerel, salmon, and eel. NHS England recommends that a healthy balanced diet include at least two servings of fish per week, one oily. However, only a tiny proportion of people meet this recommendation; according to the survey, only 27% of adults and 6% of children meet the weekly recommendation of eating oily fish.

Due to the high content of omega-3 fatty acids in oily fish (especially DHA and EPA), DHA helps to maintain vision and delay brain and vision degeneration; EPA is beneficial to cardiovascular or chronic diseases. The following are the top three oily fish with the highest recommended content according to omega-3 fatty acids:

1. Mackerel: Omega-3 content 4753 milligrams (mg)

Mackerel is small, fatty, tasty, lightly salted, and delicious fried or grilled. Mackerel is high in nutritional value, rich in omega-3 fatty acids and a good source of vitamin D, B12, selenium, and phosphorus. Contains 500% of the Reference Daily Intake (RDI) for vitamin B12 and 130% of selenium per 100g serving.

2. Salmon: Omega-3 content 3678 milligrams (mg)

Salmon is considered one of the healthiest seafood choices. It provides a good amount of omega-3 fatty acids and a good source of protein and vitamin D. Plus, it’s rich in selenium and B12, making it a very healthy seafood.
Salmon is rich in nutrition, relatively easy to cook, and full of variety. For example, slice it directly as salmon sashimi, or apply some salt or miso to turn it into grilled salmon. You can also cut it into pieces and throw it into the soup to turn it into salmon miso soup, which is nutritious and delicious.

3. Sardines: Omega-3 content 2517 milligrams (mg)

Hailing from the Atlantic, Pacific, and Mediterranean regions, sardines are small, oily fish that are nutritious and rich in omega-3 fatty acids. They’re also a good source of protein, vitamin B12, vitamin D, and minerals like calcium and selenium.

If you are considering what brand of fish oil to buy, you should eat more oily fish. Eating fish directly is the best and healthiest way to get Omega-3. Just according to the recommendations of the Seafood Guide, when eating fish, you should pay attention to eating seafood that has less impact on the environment and is not overfished, or the wild population is still sufficient so that you can enjoy the food while maintaining the sustainable safety of the ocean.
