Attenuation in fiber optics specifically refers to the loss of signal strength as light travels through the fiber optic medium over distance. This phenomenon occurs due to various factors such as scattering, absorption, and imperfections within the fiber material itself. As the light signal moves along the fiber, these factors cause the intensity of the light to diminish, which can result in a weaker signal being received at the other end.

Understanding attenuation is crucial for designing and implementing fiber optic systems, particularly in terms of ensuring that the signal remains strong enough to be accurately interpreted by receiving devices. Managing attenuation helps in determining the maximum distance a signal can travel without significant losses, which is vital for maintaining effective communication links.
