Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber that is roughly the diameter of a human hair. The light forms an electromagnetic carrier wave that is modulated to carry information. Each optical fiber is capable of carrying an enormous amount of information over great distances without amplification. However, none of this would be possible without the ability to interconnect optical fibers or terminate them at a piece of equipment. This is the job of the fiber optic installer. Fiber optic installers splice optical fibers together either mechanically or by melting the optical fibers together with a fusion splicer. They also terminate the optical fiber with a connector at a piece of equipment. In addition, installers inspect and test each installation. This article discusses everything students need to know about careers for fiber optic installers--wages, responsibilities, education and skills needed, career advancement possibilities, and more.
