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

In fiberoptic cables used to transmit communication data, what does a receiver and decoder do?

• receive the sound signal and convert to binary data

• receive the light signal and convert to binary data

• receive the audio signal and convert to analog data

• receive the direct signal and convert it to analog data

What increases the amount of information transmitted by fiberoptic cables?

• increasing the length

• using plastic instead of glass in the cable

• increasing the number of fibers

• using fewer optical amplifiers along the cable
