What does attenuation refer to in fiber optics?

Attenuation in fiber optics specifically refers to the reduction in signal strength as the light signal travels through the optical fiber. This phenomenon occurs due to various factors, including scattering, absorption, and fiber imperfections, which can diminish the intensity of the light signal over distance. Understanding attenuation is critical for fiber optic installers and technicians, as it influences the maximum distance the signals can travel without degradation, affecting overall system performance. By addressing attenuation during installation, technicians can ensure that fiber optic networks maintain high-quality transmission and achieve the necessary signal levels at the receiving end.
