THE NATURE OF LIGHT
THE NATURE OF LIGHTTo understand the use of optical fibers, it is first necessary to understand the nature of light itself. Light is to optical fiber what electricity is to conductors.Light is essentially a series of electromagnetic waves, with a few properties of particles added. When being described as a particle, light is often referred to as a stream of photons, moving from one place to another. A photon is considered to be very similar to an electron, and can be abstractly described as a primary particle of light, just as an electron may be described as a basic particle of electricity. As applied to optical fiber transmission, the particle characteristics of light are generally of lesser importance than the wave characteristics. Nonetheless, you should be aware of this dual nature (wave and parti…
