"WebReflectance is defined by the amount of light reflected compared to the power of the light being transmitted down the fiber. Thus a 1% reflectance is -20 dB, which is about what you get from a flat polished air gap connection, and 1 part per million would be -60 dB, typical of an APC connector.

Here we systematically derive the above relations from electromagnetic premises. In order to compute meaningful Fresnel coefficients, we must assume that the medium is (approximately) linear and homogeneous. If the medium is also isotropic, the four field vectors‍ E, B, D, H are related by WebReflection occurs when light moves from a medium with one index of refractioninto a second medium with a different index of refraction. Specular reflection from a body of water is calculated by the Fresnel equations.[8] Fresnel reflection is directional and therefore does not contribute significantly to albedowhich primarily diffuses reflection.
