As shown in below figure, the attenuation of an optical fiber line with the length of 12 km is 2.5 dB/km. The radius of the fiber core is 5 μm. If the optical power at the input of the fiber is 300 μW, what is the output INTENSITY at the output of the fiber?

how the attenuation affects the maximum fiber length of
communication links. Also explain how the index of refraction
parameters or the type of fiber (step vs graded) affect the maximum
data rate. Finally explain is the data rate a direct function of
the intrinsic fiber attenuation?

Optical engineers need to know the cone of acceptance
of an optical fiber. This is the maximum angle that an entering
light ray can make with the axis of the fiber if it is to be guided
down the fiber.
What is the cone of acceptance of an optical fiber for which the
index of refraction of the core is 1.75 while that of the cladding
is 1.55? You can model the fiber as a cylinder with a flat entrance...
