Systems

 

 

Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more. 

For several recent columns, I have been writing about splicing optical fibers. Last month, I covered managing fibers inside the splice trays and closures. But there is even more to know about splice closures.


The evolution of intelligent building system technology has triggered shifting roles for contractors and integrators, and the choices they make in their own specializations over the coming years can mean the difference between winning contracts and keeping customers or becoming less relevant.

Demand for wiring and cabling is expected to grow in the months and years ahead. Low-voltage applications for light-emitting diode (LED) technology and fiber optic cabling within the power-generation and telecommunications industries will help drive this market.

The 93XC OTDR is part of the Greenlee Communications family of fiber equipment.

With the increasing use of fiber optic cable in structured wiring, many electricians experienced in low-voltage copper work are extending their skills to include fiber. Working with fiber requires training and the right tools and testers to correctly install and maintain fiber optic cable.

A Wealth Of Misinformation: Harmonics and Online-Information Sources


While few would argue about of the wealth of information on the Internet, there isn’t a mechanism for qualifying its accuracy. Basically, anyone can post anything. Even such peer-reviewed sites as Wikipedia can fall short of the facts. A relatively simple concept in power is a good example.
