What wavelength should fibers be tested at to provide the most useful information?
Every single fiber has different characterizes for different wavelengths, so fiber cables
should be tested with the wavelength that is going to be use in particular sys
Define modes, classify them and what is the shape of the output of a circular
dielectric wave guide, (show different modes order)
Modes:-a mode in fiber is a path that the light is going to take down the fiber and there
are two types of modes which ar
0.15 dB for SM,MM
SM 0.10 dB
MT ARRAY 0.30-1.00 dB
0.40 dB for SM,MM
SM 0.50 dB

What would happen if :
Connecting a 1550 nm SM fiber to a 1550 nm source.
According to the specification sheet we should use 1550 nm (the wavelength should be
the same on both sides regardless of their value) on both sides to get a correct result.
What are the advantages of :
SM fiber over MM fiber
Higher Bandwidth, light will propagate further distance, less dispersion, can handle
GI-MM fiber over SI-MM fiber
Less modal dispersion, parabolic light wave that increases the capa

What is scattering? Describe its types.
If the medium through which an electromagnetic wave propagates possesses uniform
optical properties, then it passes through undisturbed. If, however, there ar
