Lecture 3: Behavior of Light in Optical Fiber

This video, from the Laser and Fiber Optics Regional Center, is the third lecture in a series of seven on fiber optics. Narrated by Dr. Mo Hasanovic, Professor of Electronics Engineering Technology at Indian River State College, this lecture covers topics related to behavior of light in optical fiber. Upon completion of this lecture students will be able to:

• Explain how optical fibers transmit light.
• Identify the basic optical fiber material properties.
• Describe the ray and mode theories of light propagation along an optical fiber. 
• State the difference between multimode and single mode optical fibers.
• Explain how optical fibers attenuate and distort light signals as they travel along the optical fiber.
• Understand the processes of light attenuation and dispersion.

Topics covered include: Anatomy of Optical Fiber, Refraction of Light, Critical Angle and Total Internal Reflection, Acceptance Angle and Acceptance Cone, Propagation of Light Through Optical Fiber, and more. The video runs 49:10 minutes in length and the other lectures in the series are available to view separately.
