  • What are some identifying qualities of twisted pair copper cabling?
    Two wires with equal and opposite signals, Transmit +/- and Receive +/-, the twisting keeps a single wire aligned away from electrical interference, pairs have different rates of twisting
  • What is the maximum supported distance of Cat 5, 5e, 6, and 6A?
    100m
  • What is the purpose of coaxial cabling?
    To allow two or more forms to share a common wire
  • What connector is most common on coaxial cables?
    RG-6 (Cable Jack)
  • What are plenum-rated cables?
    Cables with a fire-resistant jacket, used in areas where fire is either likely or would be more severe, plenum cables are not as flexible as traditional cables
  • What is the most common material used in traditional cable jackets?
    Polyvinyl Chloride (PVC)
  • What are the 2 most common materials used in plenum jackets?
    Fluorinated Ethylene Polymer (FEP) and low-smoke Polyvinyl Chloride (PVC)
  • True or False: Unshielded Twisted Pair (UTP) is the most common twisted pair cabling?
    True
  • Why might one prefer Shielded Twisted Pair (STP) cabling?
    The additional shielding either of each pair or the cable itself protects against interference
  • True or False: UTP and STP cables are electrically identical?
    False - STP cables require grounding
  • How does one read an abbreviation denoting cable type?
    (Overall Cable Protection) / (Pair Protection) TP
  • What does the abbreviation S/FTP mean?
    There is braided shielding around the entire cable and foil shielding around the pairs
  • What does the abbreviation F/UTP mean?
    There is foil shielding around the entire cable, the pairs are unshielded
  • What are 2 pros and 2 cons of optical fiber cabling?
    Signal is slower to degrade over long distances, it is immune to interference, there is no RF signal making them difficult to monitor and tap, they are more expensive
  • Why are optical fiber cables immune to interference?
    They transmit information with light signals so radio/EMF interference has no effect
  • What are the major differences between multimode and single-mode fiber?
    Multimode uses LEDs to transmit information up to 2km, single-mode uses lasers to transmit information up to 100km without processing
  • What do T568A and T568B refer to?
    The Telecommunications Industry Association (TIP) standard for pin assignments in connectors
