3.1 Twisted Pair Cables Flashcards
What is a twisted pair cable?
A type of cabling with eight insulated wires twisted into pairs to reduce electromagnetic interference (EMI).
What are the two main types of twisted pair cables?
Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP).
What are the advantages of UTP cables?
Lower cost, easier to install, widely used in LANs.
What are the advantages of STP cables?
Greater resistance to EMI due to additional shielding.
What is the maximum speed supported by Cat5 cables?
100 Mbps.
What is the maximum speed supported by Cat8 cables?
40 Gbps.
What is the maximum distance for Cat6 cables at 10 Gbps?
55 meters.
What is the maximum distance for Cat8 cables?
30 meters.
What is an RJ45 connector used for?
Ethernet networks; supports 8 pins for data and power.
What is an RJ11 connector used for?
Phone systems; typically uses 2 of its 6 pins.
What is the difference between 568A and 568B wiring standards?
568A and 568B define different pinouts; patch cables use the same standard on both ends, while crossover cables use 568A on one end and 568B on the other.
When should plenum cables be used?
In concealed spaces like ceilings, walls, and air ducts due to their fire resistance.
What are non-plenum (PVC) cables used for?
Visible areas where fire resistance is not required; less expensive than plenum cables.
What tools are commonly used for twisted pair cables?
Cable stripper, crimper, and cable tester.
What does a cable tester do?
Verifies proper wiring and connectivity.
