Week 13 Chapter 6 Part 2 - Pages 6-33 to 6-76

Question 1

Screened balanced twisted-pair cable assemblies stranded conductor is typically:

a. 22 AWG
b. 24 AWG
c. 26 AWG

Answer 1

c. 26 AWG

p 6-71

A screened cable assembly’s stranded conductor is typically 26 AWG. Because of additional capacitive electromagnetic coupling between the cable conductors and screen, screened cable assemblies can exhibit increased insertion loss compared with equivalently-sized solid conductors.

Question 2

____ connecting hardware is a one-piece pass-through unit that is reversed in its mount after the cable termination to expose the opposite side and provide a cross-connect field.

a. 66-style
b. 110- style
c. BIX-style
d. LSA-style

Answer 2

c. BIX-style

p 6-67

Unlike 110-style connecting hardware, which places clips on top of the wiring block, BIX-style equipment is a one-piece pass-through unit that is reversed in its mount after the cable termination to expose the opposite side and provide a cross-connect field (see Figure 6.30)

Question 3

Which one of the following is not an advantage associated with 110-style connectors?

a. Short termination time
b. Can be used in a number of different styles of connecting hardware
c. Allows connections to be created in one-pair increments
d. Stand-alone connectors also available in a screened version

Answer 3

d. Stand-alone connectors also available in a screened version

p 6-35

The 110-style connector’s disadvantage is that it does not exist in screened versions as a stand-alone connector.

Question 4

A majority of the modular connectors used in telecommunications are categorized as performance level 1 (PL1). Such connectors are rated for _____ mating cycles.

a. 2500
b. 1400
c. 750
d. 200

Answer 4

c. 750

p 6-44

PL 1 is rated for 750 mating cycles and PL 2 connectors (rated for 2500 mating cycles) are also available.

Question 5

Patch panel connection density is conditionally subdivided into low-density, medium density, and high-density depending on the number of connections (ports). A patch panel with 48 ports per 2 RMU would be considered:

a. Low density
b. Medium density
c. High density

Answer 5

b. Medium density

p 6-58

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