To choose the proper fiber type and construction, the application and its environment, along with the distance and bandwidth required, all go into the decision making process. Shown here is how various cable constructions for indoor installation may be used. Distribution cable is used when the fiber is being run in an area with sufficient protection, whereas armored fiber is used when the fiber has to protect itself. Dielectric fiber is similar to that of armored but there is not a metal protector. It is good for use in areas where grounding may be of concern.
