COMO FUNCIONA A FIBRA ÓPTICA

The physics of fiber optics is simple and beautiful. Simply understanding the concepts of reflection, refraction, and propagation media made it possible to build something that revolutionized telecommunications worldwide. This application even earned a Nobel Prize. The idea behind fiber optics is intriguing: light travels from a medium with a higher refractive index to another with a lower refractive index. If this light strikes at a specific angle, called the critical angle, it undergoes a process known as total internal reflection. Thus, it becomes trapped within the material. This idea led to the construction of optical fibers that deliver data over long distances.
