3.9: Attenuation Rate
The concept of attenuation rate is used in precisely the same way to relate ratios of spatial power densities for unguided waves. This works because spatial power density has SI base units of W/m(^2), so the common units of m(^{-2}) in the numerator and denominator cancel in the power density ratio, leaving a simple power ratio.

Calculate the Maximum Attenuation for Optical Fiber Links
You can now calculate the attenuation for this link. You can arrive at the total attenuation (TA) of an elementary cable section as: TA = n x C + c x J + L x a + M. where: n—number of connectors. C—attenuation for one optical connector (dB) c—number of splices in elementary cable section. J—attenuation for one splice (dB)
