Fiber-optic media (or optical fiber, or fiber, for short) are any network transmission media that use glass, or in some special cases, plastic, fiber to transmit network data in the form of light pulses.
Within the last decade, fiber optics has become an increasingly popular type of network transmission media as the need for higher bandwidth and longer spans continues. We'll begin this chapter with a brief look at how fiber-optic transmissions work.
In this chapter, you will learn to:
Understand the basic aspects of fiber-optic transmission
Identify the advantages and disadvantages of fiber-optic cabling
Understand the types and composition of fiber-optic cables
Identify the key performance factors of fiber optics
