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).
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.
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.
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.
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.
As you near the actual installation, it’s time to determine how to outfit the crews who will do the work. Choosing the proper installation and test equipment is important, as it will affect the installation time and quality and may even deter-mine the job’s profitability.
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.
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.
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.
When I was in college many years ago, my psychology professor said, “Every year, we give the same tests, but each year, the correct answers change.” We never knew if he was joking or if research really was providing new answers. But when it comes to networking options, the same phrase applies.
Managing a fiber optic project can be the easiest part of the installation if the design and planning is thorough and complete. If not, it can be the hardest. But even assuming everything has been done right, things still may go wrong, so planning for the unexpected also is important.
Higher speed fiber optic networks demand lower losses in fiber optic cabling. Since the biggest source of loss is terminations, installers are reconsidering adhesive/polish terminations because they have lower losses. How well do you understand today’s adhesive/polish terminations?
Efficient fiber optic restoration depends on finding the problem, knowing how to fix it, having the right parts, and getting it all done quickly. Like any type of emergency, planning ahead will minimize the problems encountered.
Most of the attention to fiber optic cable specifications is focused on the cable itself, not the fibers in it. But there are more choices today in fibers that require careful consideration. How well do you understand all the possible choices? Answers are on page 126.
