Lesson 3: Fiber Optic Communications
Objectives: From this lesson you should learn:
The advantages of optical fiber as a communications medium
How optical fiber is used in communications systems
Other uses for fiber optics
Why use fiber?
Fiber has become the communications medium of choice for telephones, cell phones, CATV, LAN backbones, security cameras, industrial networks, just about every kind of communications - now even all the way to the home. In this lesson, you will learn why fiber is the medium of choice for most communications networks and how many of those networks use fiber.
For those interested in more detail on how networks work, we recommend FOA Lectures 34-36 below which discuss how networks work and how bandwidth is allocated in networks.
