- 1What are the two types of cables?Twisted-pair cable
Fiber Optic - 2What is Twisted-Pair Cable?- a common copper cable used for ethernet networks
- - 3What is the signal length for twisted-pair cables? What is the speed range?up to 100ft or 328 ft
- speeds range from 10mbps to 10 Gbps - 4What kind of connector does twisted-pair cables use?RJ-45 connectors, which are slightly larger than that of a phone jack (RJ-11)
- 5What are fiber optic cables used for?mainly for WAN connections but can also be used for LANs
- 6What is the signal distance for fiber optic cables?up to 70km
- 7What is the speed range for fiber optic cables?100mbps - 10 Gbps
- 8What is the fastest cable?fiber optic
- 9What do fiber optic cables use to transmit data?Light pulses
- 10What is the advantage to fiber optic cables?less susceptible to EMI because data is transmitted by light photons not electrons
- 11What are two disadvantages with fiber optic?Expensive,
less flexible - 12what are the two types of fiber optic cables?single mode,
multimode - 13What are single mode fiber optic cables?transmit one ray of light over a long distance
- 14What are multimode fiber optic cables?carry multiple rays of light but only for about 600 meters, still 6 times longer than twisted pair cables
- 15What is the most common cable used in LANs (standard ethernet network)?unshielded twist pair cable (UTP)
- 16What does an unshielded twisted pair cable consist of?four twisted pairs of wires
- 17Advantages of unshielded twisted pair cables?helps avoid electromagnetic interference,
inexpensive and easy to install - 18What kind of cable is best for areas with high EMI such as areas with fluorescent lighting or heavy machinery?Shielded Twisted pair cable
STP - 19What is a characteristic with shielded twisted pare cables (STP)?there is an extra outer sheath around the cable
- 20What are two disadvantages with Sheilded twisted pair cabling?more expensive,
unshielded twisted pair cables are usually strong enough to combat EMI - 21What is plenum cable?a twisted pair cable that has a fire-redundant insulation jacket
- 22Why is plenum cable required for cables in the floor or wall?it gives off less toxic oder in case of a fire
- 23How many categories do twisted-pair cabling have?5
- 24What are the categories of twisted pair cabling from least fastest to fastest?Cat 3: old, carries data up to 10Mbps
Cat 5:older but still in use, capable of fast ethernet (up to 100Mbps)
Cat 5e: both 100Mbps and 1Gbps
Cat 6: up to 10Gbps but only for 55 meters instead of regular 100 meters
Cat 6a: up to 10Gbps for full 100 meters - 25What is a straight through cable used for?Most ethernet cables
- connect unlike devices to eachother - 26What is a crossover cable used for?- connect like devices to each other
- so data can transfer freely - 27What are types of interference to twisted pair cables?Nearby power cables
Electromagnetic interference
fluorescent lighting - 28What are types of interference to wireless networks?Heavy machinery, elevator shafts
Walls
Anything running on 2.4Hz like microwaves - 29What is the most common result of a damaged twisted pair cable?cross talk
