Coaxial | - Single copper wire cable surrounded in layers
- Uses RG-6 connector
- Commonly used in TV's and High-Speed internet over cable
(3.1) |
STP (Shielded Twisted Pair) | - A type of cable containing twisted-wire pairs that are not only individually insulated, but also surrounded by a shielding.
- Requires the cable to be grounded via an additional wire in the cable
(3.1) |
UTP (Unshielded Twisted Pair) | - Composed of pairs of wires twisted around each other at specific intervals.
- No additional shielding around pairs of wires
(3.1) |
Direct Burial STP | - Protected from elements
- Cable is buried in the ground
- Often filled with gel to repel water
- Shielding in the STP protects against interference
(3.1) |
Plenum | - The area above the ceiling tile for the HVAC system and usually network wires to run
- Traditional cable is Polyvinyl Chloride (PVC) and not safe against fires
- Fire Rated Cable Jackets to use in a Plenum:
- Fluorinated Ethylene Polymer (FEP)
- Low-Smoke PVC
(3.1) |
Fiber | - Transmission by light - No RF signals
- Difficult to monitor & tap
- Multimode: Short Range Communication (2km) - Uses Cheaper LED's
- Single Mode: Long Range Comm. (100km) - Uses Expensive Lasers

T568A & T568B | - The two color codes used for wiring eight-position RJ45 modular plugs.
- Neither is better than the other
- Many organizations typically use T568B
