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

Why are fiberoptic cables preferred over copper wire in telephone and Internet applications?

• used both indoors and outdoors
• easier to manufacture and install into office buildings
• more flexible and needs no power source
• less sensitive to temperature/electromagnetic interference
