In recent years, fiber optics are steadily replacing copper wires. It is a better and apt means of transmitting communication signals. Today, fiber optics cable span across long distances between local phone systems. In addition, it also serves as the backbone for many networking systems including:

1.Cable TV services
2.University campus
3.Office buildings
4.Industrial plants
5.Electric utility companies
6.Internet connectivity
7.Stereo...

Fiber Optics Cable uses pulses of light to transfer data using the event of total internal reflection. The cable has a coating of plastic. This protects the cable from exposure to heat, cold, and other weather atrocities. It also protects the cable from electromagnetic interference and ultraviolet rays of the sun. These cables are the most reliable and fastest data transfer cables on the planet.

A fiber optics cable system is very similar to the metal wire system. The fiber optics...
