These two topics—training and safety—are appropriate to cover together; properly trained installers will be safe workers, and safe workers are more likely to do careful, good work. Training also is where most installers first learn about safety, as they work in training school labs to learn how to pull, terminate, splice and test fiber optic cables. (Ed. Note: Part 6 is here.)

Testing installed optical fiber cables is the final step of any installation. But testing fiber can be done in five different ways, depending on what the standards require or what you need to know. How well do you know the options? Answers and explanations are in red. 1. All international standards require _______ testing to verify the cable plant installation. READ MORE

For many users of cabling, the first time they think of restoration is when the network goes down. It has been said that 90 percent of all network problems are cabling related, but many users are woefully ignorant of where to start restoring network operation. Let’s test your restoration savvy.

Wireless devices—including laptops, netbooks (the smaller, less powerful and cheaper PCs), iPhones, Blackberrys and regular cell phones—now dominate the news. Wireless is everywhere. I even hiked recently in a 4,500 acre nature preserve that had full Wi-Fi coverage at 50 megabits per second! In many offices, mobility is replacing unshielded twisted pair (UTP) cable to the desktop. READ MORE

Before beginning installation of fiber optic cables and hardware in a premises installation, the site must be properly prepared for the installation of fiber optic cables, hardware and transmission equipment. During the design and planning stages, the site should be inspected, and all the hardware necessary for the cable plant should be included in the design. (Ed. Note: Part 1 is here. READ MORE
