Introduction to Fiber Optics

COURSE NO: E04-049
COURSE PROVIDER: Jeffrey Cwalinski, P.E.
Introduction to Fiber Optics
Course Highlights

This online engineering PDH course will establish, through discussions, the basic concepts of fiber optics. It starts by describing the propagation of light, the ray and mode theories of light, and the phenomena refraction and reflection.  The construction of an optical cable is covered and the properties that cause optical loss and signal degradation are also discussed.


Optical fiber can be a replacement for copper conductors in communications systems.  Since it is made of glass, a dielectric, it is immune to noise. Also, since it has a higher bandwidth than copper conductors it can move more information at a quicker rate than copper.  The physical properties of optical fiber can also be changed by environmental parameters (temperature, pressure, etc.) and, as such, it can be used to sense these parameters.


This 4 PDH course is intended for electrical and computer engineers and all other personnel who are involved in designing data communications systems or sensors (i.e. pressure and temperature) and who are interested in gaining a better understanding of fiber optics.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding the nature of light propagation and the electromagnetic theory of light
  • Familiarizing with the properties of light reflection, refraction, diffusion, and absorption
  • Learning the basic optical fiber material properties and how optical fibers transmit light
  • Knowing the ray and mode theories of light propagation along an optical fiber
  • Understanding the difference between multimode and single mode optical fibers
  • Learning how optical fibers attenuate and distort light signals as they travel along the optical fiber
  • Understanding the processes of light attenuation and dispersion
  • Familiarizing with various optical fiber types

Course Quiz
Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty-five (25) questions to earn 4 PDH credits. The quiz will be based on Chapter 2 of this NAVY publication.
The minimum passing score is 70%. There is no time limit on the quiz, and you can take it multiple times until you pass at no additional cost.
