Introduction to Fiber Optics
1. Indentify the parts of the optical fiber below:
a.________________
b.________________
c.________________
2. What principle of optics keeps the light trapped in the fiber's core?
3. Describe the difference between multimode and single mode fiber. Which type is used for long distance, high speed telecommunications? Which type can be used for a local area network?
4. What is GRIN fiber? What is it used for?
5. Give four advantages of optical fiber over copper wire as an information channel in a telecommunications system.
6. Give 3 other uses (besides telecommunications) of optical fiber.
If you are in the Fiber Optics Certificate program (or just interested in learning more!) PHO K121 explains the details of optical fiber and how it is used in telecommunications.
