| What are twisted pair cables? | Copper wire cables twisted physically from each other to prevent from the wires interfering with each other. Each wire has a different rate and each cable may have a different number of twisted wire in them |
| Category 3 (CAT 3) | Ethernet Standard: 10BASE-T Distance: 100 meters |
| Category 5 (CAT 5) | Ethernet standard:100BASE-TX/1000BASE-T Distance: 100 meters |
| Category 5e (CAT 5e) | Ethernet Standard:100BASE-TX/1000BASE-T Distance: 100 meters |
| Category 6 | Ethernet Standard: 10GBASE-T Distance: 37-55 meters |
| Category 6A | Ethernet Standard: 10GBASE-T Distance: 100 meters |
| Category 7 (CAT 7) | Ethernet Standard: 10GBps Distance: 100 meters |
| What is plenum-rated cable? | The outer coating of the cable is not toxic if caught on fire |
| What is PVC cable? | Polyvinyl Chloride coats the outside jacket of the cable that is toxic when caught on fire. |
| What does UTP mean? | Unshielded Twisted Pair Most common type of cable with no shielding |
| What is STP cable? | Shielded Twisted Pair Shields each pair and/or whole cable Requires the cable to be grounded |
| What do these abbreviations mean for cabling standards: U,S,F, TP? | U=unshielded S=Braided shielding F=Foil Shielding TP=Twisted Pair |
| What are coaxial cables? | A type of cable that has two or more forms surrounding a common axis (center) doesn’t matter how you orient it, it will plug in |
| What type of cable is this? | RG-6 coax cable Used on TV/digital Supports digital up between 304-1000 meters 75 ohms resistance |
| What type of cable is this? | RG-59 coax cable Adequate for analog; does not support digital Not for long distance: 228 meters 75 ohms |
| What is the T568A wiring standard in color order? | |
| What is the T568B wiring standard in terms of color order? | |
| what is most important to remember about the TIA/EIA T568A and T568B wiring standard? | You have to use one or the other; you can’t mix the two when wiring your building |
| What are some characteristics of fiber network cables? | Transmission of light No radio frequency so no interference or hacking Slow to degrade; best for long distance Typically an orange or yellow wire |
| What is Multi-Mode Fiber? | Fiber cable that is best for short communication up to 24 meters “Multi-mode” because light bounces off the walls of the cable Uses cheaper light sources like LED’s |
| What is Single-Mode Fiber? | Fiber cabling best for long distance up to 100km “Single-Mode” because light travels in one stream Uses light sources like lasers; very expensive |
| What are VGA cables? | Video Graphics Array Video cable type Many form factors but typically come in a blue cable or blue interface |
| What DB/DE (D-sub)cables? | Type of VGA video cable “D” refers to the type and letters “A-E” refers to the size Accompanied by a number that refers to the number pins *The name of the cables are always interchangeably named |
| What is the distance for D-Sub cables? | 5-10 meters |
| What are HDMI cables? | high-Definition Multimedia Interface Video cable type Supports video and audio streams All digital, no analog Many types |
| What are DisplayPort? | Royalty-free standard Compatible with HDMI and DVI Have a locking button only on DisplayPort not miniDisplayPort |
| What are DVI cables? | Digital Visual Interface Many types: Single/Dual link DVI-A DVI-D DVI-I |
| What are the specs of single link DVI cables? | 3.7 GBPs (HDTV) 60 FPS |
| What are the specs for DVI dual link cables? | 7.4 GBps (HDTV) 85 fps |
| What are DVI-A cables? | Supports analog signals |
| What are DVI-D cables? | Supports Digital signals |
| What are DVI-I cables? | Integrated both digital and analog on the same connector |
| What are Lightning cables? | Multipurpose cables Apple proprietary 8 pin digital signals USB type A connector Higher power output to charge devices Can be inserted either way |
| What is a Thunderbolt cable? | Multipurpose cable Primarily used for video High speed serial connector Data and power on the same cable Based on miniDisplayPort standard Many versions |
