OCN-Q7

What is a skew ray in an optical fiber?

• A) A ray that propagates along the axis of the fiber

• B) A ray that travels in a helical path around the core of the fiber

• C) A ray that is completely absorbed by the cladding

• D) A ray that reflects off the core-cladding boundary at a right angle

How does a skew ray differ from a meridional ray in an optical fiber?

• A) A skew ray travels straight through the fiber, while a meridional ray spirals

• B) A skew ray does not intersect the fiber axis, while a meridional ray does

• C) A skew ray is absorbed by the core, while a meridional ray is absorbed by the cladding

• D) A skew ray reflects off the core, while a meridional ray refracts

Which of the following factors can influence the behavior of skew rays in an optical fiber?

• A) Core-cladding refractive index difference

• B) The wavelength of the light used

• C) The diameter of the core

• D) All of the above

In which type of optical fiber are skew rays more likely to be observed?

• A) Single-mode fiber

• B) Multimode fiber

• C) Polarization-maintaining fiber

• D) Photonic crystal fiber

How can the presence of skew rays be minimized in an optical fiber communication system?

• A) By using a smaller core diameter

• B) By increasing the numerical aperture

• C) By using single-mode fibers

• D) By using a higher wavelength of light
