What are two common causes of signal degradation when using UTP cabling? (Choose two.)

  • loss of light over long distances
  • low-quality cable or connectors
  • low-quality shielding in cable
  • installing cables in conduit
  • improper termination
Explanation & Hint:

Signal degradation, also known as attenuation, in UTP (Unshielded Twisted Pair) cabling can be caused by various factors. The two common causes from the options provided are:

  1. Low-quality cable or connectors: The use of inferior materials can result in increased resistance and crosstalk between the wires inside the cable, which can degrade the signal strength and quality as it travels along the cable.
  2. Improper termination: If the UTP cables are not terminated correctly, it can lead to reflections, crosstalk, and insertion loss. Proper termination is critical to ensure that the signal integrity is maintained and that the connection is reliable.

The other options listed are not typically associated with UTP cable signal degradation:

  • Loss of light over long distances applies to fiber optic cables, which transmit light, not electrical signals as UTP does.
  • Low-quality shielding in cable refers to shielded twisted pair (STP) rather than UTP. UTP does not have shielding; its design relies on twisted pairs to counteract electromagnetic interference.
  • Installing cables in conduit does not inherently cause signal degradation; however, if the conduit is overfilled or if the cables are bent at sharp angles, it can potentially damage the cables and affect signal quality.
