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

For what are Fiber Optics mainly used?

• Long distance communication
• Imaging
• Phones
• Downloading Apps

How does light travel through the cable?

• Refraction and Reflection
• Refraction only
• Dispersion
• Total Internal Reflection

A fiber optic adapter also called _________________ is designed to connect two fiber optic cables together.

• Couplers
• Copper Adapters 
• Cable Joins
• Cable Ties

What are the types of optical fiber?

• Material

• Number of modes

• Refractive index profile

• All the above

Physical parameters are sensed directly is

• Active sensor

• Intrinsic sensor

• Passive sensor

• Both 1 and 2

Example for passive sensor

• Displacement sensor

• Temperature sensor

• Pressure sensor

• None

A light wave acting as a carrier wave is capable of carrying

• less information

• more information

• medium information

• No information

Single mode fiber is

• one mode

• two mode

• more than one mode

• none

Step index multi mode fiber has

• core diameter has 50 to 200 µm

• core diameter has 100 to 200 µm

• core diameter has 50 to 100 µm

• core diameter has 50 to 150 µm
