Q

What are the advantages of BIX-style connectors?

A
  • High quality, reliable, and durable electrical contact
  • High transmission performance characteristics
  • Simple, inexpensive design
  • Short termination time
  • Allows connections to be created in one-pair increments
  • Wide range of connector configurations
  • Can be used in a number of different styles of connecting hardware
  • Patch cords used for cross connections and interconnections to BIX style connectors can be terminated in the field with 100 percent transmission compliant BIX-plugs
  • High density of terminations
17
Q

What are the disadvantages of BIX style connectors?

A
  • It is not widely used by the industry
  • The conductor termination is performed with a special tool
  • It is nonexistent in screened versions as a stand-alone connector
18
Q

Balanced twisted pair cable designations use an x/y designation where x is the overall screen type and Y is the individual pair screen type. For the x designations what does the following letters designate a cable have?

U = \_\_\_\_
F = \_\_\_\_
S = \_\_\_\_
SF = \_\_\_\_
A 
U = Overall screen absent
F = Overall foil screen
S = Overall braid screen
SF = Dual overall screen (foil braid)
19
Q

Balanced twisted pair cable designations use an x/y designation where x is the overall screen type and Y is the individual pair screen type. For the y designations what does the following letters designate a cable have?

U = \_\_\_\_
F = \_\_\_\_
A 
U = Individual screens absent
F = Individual foil screens

Q

24 AWG stranded copper patch cords attenuate up to ___ more than solid cables.

A) 10 percent
B) 15 percent
C) 20 percent
D) 30 percent

A

C) 20 percent

Copper patch cords should be constructed with stranded cable to allow flexibility.

21
Q

What are the three levels of patch panel connection densities?

A

Low density with the following number of connections (ports):
12 or 16 per 1 RMU
24 or 32 per 2 RMU
48 per 3 RMU

Medium density with the following number of connections (ports):
24 per 1 RMU
48 per 2 RMU

High density with the following number of connections (ports):
48 per 1 RMU

22
Q

True or False

A time domain reflectometer (TDR) test is a required acceptance testing for balanced twisted-pair cabling.

A

False
TDR sends pulses of energy through the cabling, and when the pulses encounter the end or a fault, it reflects a portion of the pulse energy back.
TDR is a powerful tool for troubleshooting cabling problems.

23
Q

T568A has 8 position pin/pairs in what pair order?

A 
Pair 3 (1,2; White Green)
Pair 2 (3,6; White Orange)
Pair 1 (4,5; Blue, White)
Pair 4 (7, 8; White, Brown)
24
Q

T568B has 8 position pin/pairs in what pair order?

A 
Pair 2 (1,2; White Orange)
Pair 3 (3,6; White Green)
Pair 1 (4,5; Blue, White)
Pair 4 (7, 8; White, Brown)
25
