Not all fiber optic systems are the same, and one big difference is the wavelength used for transmission. The wavelength affects performance, testing and the choice of components, so let’s see how well you understand it. Correct answers and explanations are in red. 1. READ MORE

Those of us who have been in fiber optics for a long time have gotten tired of hearing about the “advantages of fiber optics,” e.g., higher bandwidth, longer distance capabilities and immunity to electrical interference. But one application certainly effectively applies those capabilities of fiber: the industrial market. We’re all familiar with the typical industrial environment. READ MORE

Communications cabling installations follow rules—some mandatory, some advisory—covered by what we call standards and codes. In my experience, these two sets of rules are often confused, so let’s see how well you understand them. Correct answers and explanations are in red. READ MORE

While most of the talk about expanding broadband access for the American public has focused on rural customers, much of the activity is in metropolitan areas. Metro networks are expanding rapidly because they encompass many types of networks, not just broadband Internet. READ MORE

Last month, I discussed the current status of broadband networks and the emergence of wireless as the preferred connection, since most users want mobility for their broadband-connected devices. Often, I find people think wireless means no more fiber optics (or any cabling at all), but that’s hardly the case. READ MORE

Around the world, billions of dollars are being spent trying to bring “broadband” to everyone. However, broadband is defined loosely. Some say anything over 1 megabit per second (Mbps) is broadband, while others are looking at much higher speeds. Cellular wireless defines broadband at much slower speeds than fiber to the home (FTTH), cable modem or digital subscriber line (DSL) service. READ MORE

No, not the great outdoors but big buildings, convention centers, airports, hotels, casinos and other large public spaces. They require special cabling considerations because of the size of the space and the number of users. How well do you understand designing and installing cabling for big spaces? Correct answers and explanations are in red. READ MORE

Networks and links continue to get speedier, but at some point, they require faster cabling to support them. You may need to upgrade copper to faster copper, copper to fiber or even older fibers to quicker ones. How well do you know the rules? Answers and explanations are in red. READ MORE

Every year, I review the hot applications and technology that affect contractors working with fiber optics. Last year, controversies over bend-insensitive fiber and multimode testing were big news. The controversies, however, are already blowing over, as they are simply “growing pains” as new fiber optic technologies were introduced. READ MORE
