Each year, before I write about events of the previous year and possibilities for the year just begun, I review my old columns to see what has changed. As I read last year’s column, I found myself nodding, yep, that’s about the same this year and that and that, too. READ MORE

Much of the fiber used in premises applications for computer networks and closed-circuit security cameras is multimode fiber. Multimode fiber has special application and installation quirks you need to know to install and use it separately. How familiar are you with multimode? Answers and explanations are in red. READ MORE

The problem when dealing with technology is that it is always changing. Planned obsolescence sometimes means change for change’s sake (such as bigger tailfins on cars in the 1950s). In our businesses, however, it often means the new technology offers new application opportunities. Let’s test your knowledge of some of these changes. Answers and explanations are in red. READ MORE

Installed cables often need to be joined together to complete a cable plant route; the route may be too long to pull or to place a continuous length of cable, since cable can only be manufactured in lengths of around 5 kilometers (km). One cable may be split to feed two or more cables, or even multiple cables will need to be interconnected at a single point. READ MORE

Industrial automation systems have become big users of fiber optics and copper cabling. Industrial applications of premises cabling usually have more stringent needs than commercial applications. How well do you understand industrial cabling? Answers and explanations are in red. 1. Industrial cabling generally has more stringent requirements for __________than office cabling. READ MORE

The Installation of fiber optic cable is a very broad subject, mainly because every project is different. Proper installation requires good judgment, patience and care in handling the cable. Instead of trying to cover all installation types, let’s examine some guidelines that can be applied in most. READ MORE

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

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
