Fiber is just as easy, and sometimes easier, to install than copper. Remember, since fiber is accepted as the standard choice for communications backbones for many years, today's installers are comfortable with the technology. In fact, new generation high-speed copper networks. such as Category 5e and Category 6 Unshielded Twisted Pair (UTP) cable -- require more stringent and time-consuming installation techniques than those of fiber. Compared to newer grades of copper cable, fewer regulations exist on the methods by which optical cable is pulled and terminated. In addition, there is no need to worry about the location of EMI/RFI sources during installation. Furthermore, optical fiber cables are stronger, lighter and smaller than comparable copper cable designs, and there are few routing restrictions, particularly in areas with other electrical power cables.
