3.1 - Explain basic cable types, features and their purposes. Flashcards
(33 cards)
Ethernet - CAT 5
Max supported distance: 100 Meters
Max supported throughput: 100Mbit/s
Ethernet - CAT 5E
Maximum supported distance: 100 Meters
Maximum supported throughput: 1GB/s

Plenun-rated cable
Fire-rated cable jacket
Fluorinated ethylene polymer (FEP) or low-smoke polyvinyl chloride (PVC).
Ethernet - STP
Sheiled Twisted Pair
Additional shielding protects against interference.
Shield each pair and/or the overall cable.
Requires the cable to be grounded.
Ethernet - UTP
Unshielded Twisted Pair.
No additional shielding.
The most common twisted pair cabling.
T568A and T568B Termination
Pin assignments from EIA/TIA-568-B standard.
Eight conductor 100-ohm balanced.
Twisted-pair cabling.
T568A and T568B are different pin assignments for 8P8C connectors.
Assigns the T568A pin-out to horizontal cabling.
Many organizations traditionally use 568B.
You can’t terminate one side of the cable with 568A and the other with 568B.
568A Pin-out
568B
Fiber
Transmission by light.
The visible spectrum.
No RF signal.
Very difficult to monitor or tap.
Multi-Mode Fiber
Short range communication up to 2km.
Inexpensive light source.
Single-mode Fiber
Long range communication up to 100km.
Expensive light source.
Coaxial
Two or more forms share a common axis
RG-6 used in television/digital cable and high-speed Internet over cable.
RG-59 used as patch cables not designed for long distances.
RG-6
A type of Coaxial cable used in television/ digital cable and high-speed internet over cable.
Thicker and beefier cable than RG-6.
RG-59
Form a coaxial cable used as patch cable.
Not designed for long distances.
