Question 2

Cable crimpers

Answer 2

• “Pinch” the connector onto a wire
  – Coaxial, twisted pair, fiber
• Connect the modular connector to
  the Ethernet cable
  – The final step of the process
• Metal prongs are pushed through the insulation
  – The plug is also permanently pressed
  onto the cable sheath

Question 3

RJ45s connectors need to be connected to either net cables
crimper removes the ___ from the end of a wire

Answer 3

sheith

Question 4

wire types cat5 cat6
there are differnet__ for cable typers

Answer 4

connectors

Question 5

WIFI analyzer

Answer 5

information about what frequencies are in use and which ones are open
will show what interferes may happen
shows you if you may need to relocate a wifi Antena

Question 6

Toner generator/probe

Answer 6

used to find a cable
adds signal to copper wire

you have to connect a tone generator to one end of the cable

inductive prove doesnt need to touch copper wire just needs to get close

Question 7

Punch down tool

Answer 7

put each wire into there slot on a punchdown block
pushes down the wire and cuts off any extra

Question 8

cable testers

Answer 8

two units
lug each one to two end of the cable
it’ll tell you where each pin is connected
can’t tell you if there is cross talk signal loss
to do that you need a time domain reflextomider

Question 9

loopback

Answer 9

test the interface of a device by looping the wire out of the device and back it
use rs 232 9 pin of 25 pin
you can also use ethernet cable t1 and fiber

Question 10

Taps and port mirrors

Answer 10

physical data tap
you place this in the middle of a data link
you can send that data to an analyzer
same thing as a port mirror a function built into a switch

Question 11

Twisted pair copper cabling
how many pair of wire on the inside
he pairs consist of _ and ___
some pair are twisted ___ then overs

Answer 11

what we use for Ethernet
4
the pairs consist of transmit+ and transmit -
tighter

Question 12

coaxial cable

Answer 12

• two or more forms that share a common axis
• RG6 used in tv digital cable

Question 13

Plenum space

Answer 13

in buldings that have a drop ceiling the air that is leaving the building goes through a space called the plenum
all of network cables are in this area as well

Question 14

plenum rated cable

Answer 14

the jacket or or what surrounds the wire is a called a polyvinyl chloride

if the company is putting there wires in a plenum they ll need wires such as

flourinated ethylene plymer FEP
or low smoke plyvinyl chloride PVC

plenum rated cable may not be a s flexible but they are safer in a fire

Question 15

UTP stand for

Answer 15

unshielded twisted pair
no additional shielding
most common twisted pair cabling

Question 16

stp

Answer 16

shielded twisted pair
Additional shielding protects against interference
– Shield each pair and/or the overall cable
– Requires the cable to be grounded

Question 17

• Abbreviations on the outside of the wires
  u
  s
  f

Answer 17

– U = Unshielded
– S = Braided shielding
– F = Foil shielding

Question 18

Direct burial STP
when you need to run a wire outside

Answer 18

• Provides protection from the elements
  – Designed to be waterproof
  – Often filled with gel to repel water
  – Conduit may not be needed

Question 19

Optical fiber communication

Answer 19

• Transmission by light
  – The visible spectrum
• No Radio Frequencies signal
  – Very difficult to monitor or tap
• Signal slow to degrade
  – Transmission over long distances
• Immune to radio interference - There’s no RF

Question 20

Multimode fiber

Answer 20

• Short-range communication
  – Up to 2 km
• Relatively inexpensive light source
  – LED is used to send light through fiber

Question 21

Single-mode fiber

Answer 21

• Long-range communication
  – Up to 100 km without processing
• Expensive light source
  – Commonly uses lasers to send light through the fiber

Question 22

What is ISO/IEC 11801

Answer 22

classes of networking standards of cables

Question 23

TIA telecommunications industry association

Answer 23

– Standards for cables, market analysis, trade shows,
government affairs, etc.
– ANSI/TIA-568: Commercial Building
Telecommunications Cabling Standard

Question 24

What is T568A and T568B

Answer 24

Pin and pair assignments of eight-conductor 100 ohm balanced twisted pair cabling

what colors to be used for what wires

gives you two options two standards that companys can choose they both do the same thing

Question 25

USB 1.1
– Low speed: __megabits per second, ___ meters
– Full speed: ___megabits per second, ___meters

Answer 25

– Low speed: 1.5 megabits per second, 3 meters
– Full speed: 12 megabits per second, 5 meters

Question 26

• USB 2.0 - ___megabits per second, __ meters

Answer 26

• USB 2.0 - 480 megabits per second, 5 meters

Question 27

• USB 3.0 - SuperSpeed– __ gigabits per second, ~__ meters
  – Standard does not specify a cable length

Answer 27

– 5 gigabits per second, ~3 meters
– Standard does not specify a cable length

Question 28

USB-C
* USB has a lot of different connectors
* USB-C replaces all of these
– One connector to rule them all
* USB-C describes the physical connector
– It doesn’t describe the signal

Question 29

Thunderbolt

Answer 29

• High-speed serial connector
  – Data and power on the same cable
  – Based on Mini DisplayPort (MDP) standard
• Thunderbolt v1
  – Two channels
  – 10 Gbit/s per channel, 20 Gbit/s total throughput
