10BASE2
UTP Coupler
connects 2 cables to make a longer cable
Cat 3
10BASE-T
100 Meters
F connector
cable tv and cable modem connectors
Cat 5e
100BASE-TX
1000BASE-T
100 meters
Cat 6
10GBASE-t
37 to 55 meters
Cat 3
10BASE-T
100 Meters
data rate of 10 Mbps with a max rate of 16 Mbps
Cat 5
100BASE-TX 1000BASE-T 100 Meters ATM traffic at 155 Mbps 4 pairs of 24 gauge wires 1 twist every 5 cm
Cat 5e
100BASE-TX 1000BASE-T 100 meters 1 Gbps reduces crosstalk
Cat 6
10GBASE-t
37 to 55 meters
thicker insulation
reduces cross talke
Cat 6a
10GBASE-T
100 meters
2x as many frequencies as Cat 6
ST
Straight tip
push and twist
Commonly used with MMF
SC
square connector
push and pull to remove
LC
Lucent Connector
push- press tab and pull to remove
MTRJ
Media termination recommended jack
2 fibers strands in one connector - transmit and receive
push and pull
FC
field assembly connector
Fiber Coupler
connect 2 fiber cables back to back
Single Mode
smaller diameter
only 1 mode of propagation
longer distance limitation
more expensive
Multiple Mode
2 types of glass
similiar to coaxial
bits can arrive out of order due to different modes of propagation
Cable Crimper
pinch the connector onto the wire
final step of cable installation
Punchdown Tool
forces wire into wiring block
trims the wires
breaks the insulation
Wire Strippers
easily remove insulation from copper wire
Snips
precise cutting
wire stripping and cutting notches
OTDR
estimate fiber lengths measure signal loss determine light reflection creat wire maps expensive requires additional training
Straight Through
white and orange = pin 1 orange = pin 2 white and green = pin 3 blue = pin 4 blue and white = pin 5 green = pin 6 white and brown = pin 7 brown = pin 8
Crossover
White and orange = pins 2&3 orange = 2&6 white and green = 3&1 blue = 4&7 white and blue = 5&8 green = 6&2 white and brown = 7&4 brown = 8&5
rollover
white and green = 1&8 green = 2&7 white and blue = 3&6 blue = 4&5 white and orange = 5&4 orange = 6&3 white and brown = 7&2 brown = 8&1
