Optical attenuation in power fiber optic cables
Attenuation in fiber optics is the gradual loss of light signal strength as it travels through a fiber cable. This can be due to a variety of factors: scattering and absorption, intrinsic loss, extrinsic loss, bending losses and more. If you don't know what kind of losses to expect in your system, you won't know how many other components. As the distance light travels through an optical fiber increases, the light's strength decreases; this phenomenon is known as “fiber attenuation. Optical fiber is our first. 📦 For purchasing, use the RP Photonics Buyer's Guide for fiber-optic attenuators.
