Understanding Fiber Optics Communication

Course Overview

This course provides the foundation essential to developing, debugging, characterizing, and manufacturing cutting edge optic fiber components and networks. Based on the science that enables the technology, the course provides an accurate intuitive grasp of fiber optics.

The passive network components, like filters, multiplexers/demultiplexers, couplers, isolators, etc, are all based on the concepts of coherence and interference described with examples like the behavior of waves in a pond. For active devices like transmitters, modulators, receivers, and amplifiers, atomic transitions – spontaneous emission, stimulated emission, Raman scattering and absorption – are presented in a conceptual way that is simple but accurate.

What You'll Learn

• Part 1 - Overview The science in four easy pieces
• High speed, long distance networking
• How information is carried by optic fibers
• The 40,000 foot view of a Dense Wavelength Division Multiplexing (DWDM)
• Part 2 – Optic fibers Fiber structure
• How fibers carry information
• The index of refraction and Total internal refraction
• Modal dispersion and multimode fibers

Understanding fiber optics communication This course provides the foundation essential to developing, debugging, characterizing, and manufacturing cutting edge optic fiber components and networks.

The problems caused by chromatic and Polarization Mode Dispersion (PMD) are described by showing light shining through a prism, on the one hand, and through sunglasses, on the other. In every example, components are put in the context of a wide area Dense Wavelength Division Multiplex (DWDM) network.
