Last month, I discussed equipping installers with the tools needed for installations. Installers also need test equipment. There are many options in the sophistication and cost of fiber optic test equipment. Proper selection can reduce both equipment costs and testing labor costs. The types and quantities of test equipment required also will vary by job type. (Ed. Note: Part 5 is here.) 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. Correct answers and explanations are in red. READ MORE

Outside plant installation (OSP) of fiber optic cables can be a more diverse process than premises installations. OSP installs may include placing aerial or underwater cable, direct-buried cable, cable in conduit or installing conduit or innerduct and then pulling cable. A single link may use several types of installation. READ MORE

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

The corporate network is undergoing a major shift in emphasis that impacts cabling tremendously. The “traditional” corporate network that uses fiber optic backbones and category-rated unshielded-twisted pair (UTP) copper to the desktop is becoming a dinosaur. READ MORE

Fiber optic cables are designed to protect the fibers, ease installation, and meet building codes and/or industry standards. This quiz will test your basic knowledge of fiber optic cables, their applications and their installation. You can find the answers in the new FOA Online Fiber Optic Reference Guide (www.thefoa.org/tech/ref), especially the section on fiber optic cables. READ MORE
