With the use of unshielded twisted-pair copper wire in a network, what causes crosstalk within the cable pairs?

  • the magnetic field around the adjacent pairs of wire
  • the use of braided wire to shield the adjacent wire pairs
  • the reflection of the electrical wave back from the far end of the cable
  • the collision caused by two nodes trying to use the media simultaneously
Answers Explanation & Hints:

Crosstalk is a type of noise, or interference that occurs when signal transmission on one wire interferes with another wire. When current flows through a wire a magnetic field is produced. The produced magnetic field will interface the signal carried in the adjacent wire.
