What does the term “attenuation” mean in data communication?

  • loss of signal strength as distance increases
  • time for a signal to reach its destination
  • leakage of signals from one cable pair to another
  • strengthening of a signal by a networking device

Explanation: Data is transmitted on copper cables as electrical pulses. A detector in the network interface of a destination device must receive a signal that can be successfully decoded to match the signal sent. However, the farther the signal travels, the more it deteriorates. This is referred to as signal attenuation.
