Fiber Optics

How do Fiber Optics work?

• By connecting and transferring energy
• By remitting and subtracting power from other fiber optics
• By using light pulses to transfer data
• By converting sound waves in to binary code

What is the primary advantage of using Fiber Optics over traditional copper cables?

• Lower installation cost

• Less susceptible to electromagnetic interference

• Higher bandwidth capacity

• Easier to repair

Which of the following materials is commonly used in the core of Fiber Optic cables?

• Copper

• Aluminum

• Plastic

• Glass

What phenomenon allows Fiber Optics to transmit light over long distances?

• Absorption

• Diffraction

• Refraction

• Reflection

What principle allows light to propagate through an optical fiber?

• Refraction

• Diffraction

• Total Internal Reflection

• Dispersion

The core of an optical fiber is made of:

• Metal

• Plastic or Glass

• Rubber

• Copper

Which parameter determines the maximum angle for light to enter the fiber and still be guided?

• Numerical Aperture (NA)

• Refractive Index

• V-Number

• Attenuation

What is the condition for Total Internal Reflection (TIR) in optical fibers?

• Light must travel from a higher to a lower refractive index.

• Light must travel from a lower to a higher refractive index.

• The incident angle must be greater than the critical angle.

• The incident angle must be less than the critical angle.

What is the main function of the cladding in an optical fiber?

• To absorb light

• To protect the core

• To reflect light back into the core

• To increase signal speed
