j - number of large waves across the fiber

m - smaller details of the pattern


Absorption: Related to the fiber material
Scattering: Related to fiber material and structural imperfections
Radiation: Related to perturbations, both macroscopic and microscopic
x-axis: as it moves away from the origin, depicts
increasing signal quality aka reducing signal loss
y-axis: db loss

blue line is just a slope indicating with increasing


signal loss(x moving towards 0, loss in dB
increases)

red dotted line - 32% of the signal is lost at 5dB


blue dotted line - 50% of the signal is lost at 3dB

if 0.3dB/km is alpha, at 10km, 0.3*10 = 3dB, 50%


of the signal is lost
at 0.5dB/km, 0.5*10 = 5dB, 32% of the signal is
lost
(200*10^-6)*10^(az)/10
