Which two factors may interfere with the copper cabling and result in signal distortion and data corruption? (Choose two.)
- EMI
- crosstalk
- RFI
- signal attenuation
- extended length of cabling
Explanation: EMI and RFI signals can distort and corrupt data signals that are carried by copper media. These distortions usually come from radio waves and electromagnetic devices such as motors and florescent lights. Crosstalk is a disturbance that is caused by adjacent wires bundled too close together with the magnetic field of one wire affecting another. Signal attenuation is caused when an electrical signal begins to deteriorate over the length of a copper cable.
