How many times does fiber optic patch cord experience the greatest optical attenuation

How many times does fiber optic patch cord experience the greatest optical attenuation

Scattering accounts for the greatest amount of attenuation in a fiber cable, between 95 and 97 percent. Light traveling through the fiber interacts with the densities as shown in the light and is then partially scattered in all directions. Fiber optic cables have many advantages, but one of the downsides just like with copper cable, is that it can experience what is called attenuation. Attenuation refers to the loss of light as it travels down the fiber. This can be due to a variety of factors: scattering and absorption, intrinsic. This attenuation is inevitable, so the smaller the attenuation value, the longer the transmission distance of the same optical power. The better the quality of this fiber patch cable.
