21. Network Cables & Connectors Flashcards
Twisted pair and coaxial are covered with plastic. What are two common “grades” or types of plastic that you can purchase with these cable types?
PVC or Plenum
Why might you choose a plenum type cable?
Because you are worried about the risk of fire
What are two common coax RG types?
RG-6 and RG-59
Between RG-6 and RG-59, which coax cable has the thicker core?
RG-6
About how long can RG-6 be run in feet?
About 1000 feet
Where do we often see RG-6 in our home?
For cable telelvision and cable modem connections
What component do you use with coax cable when you want to run many different feeds from a single connection?
A splitter
Why might a splitter cause a problem in a coax environment?
The signal can degrade when you add splitters to the topology
What are two common coaxial connectors that you should know?
The BNC type and the F-connector
What is the most popular type of network cabling in use in the world today?
Twisted Pair
What are the two major forms of twisted pair?
Unshielded Twisted Pair and Shielded Twisted Pair (UTP and STP)
What are there twists in UTP?
The twists are used to reduce the interference
What are the two categories of UTP that are so old, we typically no longer encounter them in networks today?
Cat 3 and Cat 4
What is the maximum transmission distance for UTP?
100 meters (328 feet)
What is the first category of UTP that can transmit at 100 Mbps?
Category 5 (Cat5)
What is the common connector type for a POTS phone line?
An RJ-11 connector
What is the common connector type for a Cat 5 UTP cable?
RJ-45
What are the two wiring standards that are found today with UTP?
568A and 568B
You have a straight through UTP cable that uses 568B at one end. How will the other end be pinned?
568B
What is a crossover UTP cable used for?
In order to similar network devices (like two computers) to communicate directly
What are two major types of fiber optic cable?
Single Mode and Multi Mode
What type of fiber cable is used for long distances?
Single Mode fiber
What type of fiber cable is used for shorter runs of cable (typically)?
Multi mode fiber
What is a typical speed for multi mode fiber?
10 Gbps
