http://electron9.phys.utk.edu/optics421/modules/m8/optical_fiber_measurements.htm WebThe attenuation coefficient, Γ, in dB/km is found by dividing the loss, L, by the length of the fi-ber, z. The attenuation coefficient is then given by (6.6) The total attenuation can be found by multiplying the attenuation coefficient by the fiber length, giving a logarithmic result, in dB, for the fiber loss.
