As countries continue to develop networks for global communication, fiber optics offers a method of transmission that allows for clearer, faster, more efficient communication than copper. A number of characteristics make optical fiber well-suited to video transmission. This chapter discusses the basics behind optical fiber transmission.
The principle of total internal reflection governs the operation of optical fiber. An image in a mirror represents only 90% of the reflected light. Total internal reflection reflects 100% of the light. Total internal reflection occurs because light travels at different speeds in different materials.
A dimensionless number called the index of ...
