Fiber Media System
This chapter is an overview of the process you need to follow when you apply
fiber media. Some of the information in this chapter repeats in subsequent
chapters for instructional purposes.
Why Choose a Fiber-optic
Media System?
Fiber media holds many advantages over traditional copper media. Since
fiber-optic media transmits digitized information via light pulses over glass or
plastic fibers, it avoids many of the problems common with copper applications.
In certain applications, the advantages of fiber over coax media outweigh the
higher cost of fiber media and components.
