Now that you have learned about the basic designs of optical fibers, the next step is to understand the properties of fibers important for light transmission. I have already touched upon many properties in Chapter 4; this chapter examines them more thoroughly.
The most important properties for communications are attenuation, light collection and propagation, fiber dispersion, and mechanical strength. Nonlinear effects can be important in some cases, particularly for sensing and high-performance systems. I will start with the property usually at the top of the list— attenuation.
