The Language of Low-Voltage Copper Cabling
Recently, I have been focusing on the language of fiber optics, since you need to know the language of a subject to understand it. Let’s take a break from fiber and look at the language of low-voltage copper cabling.

The Language of Networks
Like fiber optic and copper cabling, networks have their own language, much of it based on TLAs (three letter acronyms). Many of your customers probably speak this language already, so let’s test your understanding of it.

Prefab Cabling Networks
Prefabricated cabling systems for fiber optic networks have become popular for premises installations, fiber to the cell tower antenna and fiber to the home. Prefab systems reduce installation time because they don’t need termination, but they require different knowledge, skills and procedures to make them work properly. How prepared are you for those differences?

How Many Multimode Fibers?
Multimode fiber has had many variations, almost as many as unshielded twisted-pair copper cable and for most of the same reasons—the search for bandwidth for higher speed networks. How well do you know (or remember) all of the varieties of multimode fiber?

Fusion Splicing Fiber Optics
Fusion splicing has always been used in outside plant fiber optic installations, but the recent move toward single-mode fiber in premises applications has led to increased interest in this method of splicing and terminating fibers. How familiar are you with fusion splicing?

New Uses for Old Cables
Traditionally, upgrading to a higher speed network meant installing new cabling. Now, some system and network companies are proposing new ideas for using older cabling designs for new applications. This means that some network upgrades can be made without installing new cabling. Have you kept up with these new developments?
