1.
|
The
three types of optical
fiber are _______.
|
True/False
Indicate whether the statement is true or false.
|
|
2.
|
Singlemode
fiber becomes
singlemode when the core diameter is decreased to just a few
times larger than the wavelength of
light it transmits.
|
|
3.
|
Light
rays bend at the boundary
of two optical materials (like water and air or two types of
glass) due to the change in the index of
refraction of the materials.
