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...
Optical fiber as a guided media, what is the future and new
technological advances of optical media? What are characteristics
of data rate, and maximum distance of optic fiber and are there any
limitation or concerns with the use of this media
Explain in your own words why light is trapped in an optical
fiber.
Describe at least two cases where you have observed the effects
of light refraction besides the case of a swimming pool. Use
examples from your own life.
Why the fabrication of optical fiber is a very delicate
process?
What do you understand is the "Dispersion" effect in
communication fibers

(a) Explain the principle of transformer action.
(b) Derive an expression for the e.m.f. induced in a transformer
winding. Show that emf per turn in primary is equal to e.m.f. per
turn in the secondary.
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?
