C7 Network Cabling & Data Infrastructure 2

Question 1

What is the maximum pulling tension allowed for a 4-pair Cat 6 UTP cable during installation?

Accepted Answer

25 lbf

Answer

TIA-568 specifies a maximum pulling tension of 25 lbf (110 N) for 4-pair UTP cables to prevent damage to the conductors and insulation.

Question 2

Which connector type is used for terminating Cat 6A cabling in a high-density 10GbE data center patch panel?

Accepted Answer

RJ-45 (8P8C)

Answer

Cat 6A copper cabling uses the standard RJ-45 (8P8C) connector, which supports 10GbE up to 100 meters.

Question 3

What is the minimum bend radius for a Cat 6 UTP cable after installation (static bend)?

Accepted Answer

4 times the cable diameter

Answer

TIA-568 requires a minimum static bend radius of 4 times the cable's outer diameter to prevent pair separation and return loss degradation.

Question 4

In a structured cabling system, what is the maximum distance allowed for horizontal cabling from the telecom room to the work area outlet?

Accepted Answer

90 meters

Answer

TIA-568 limits the permanent horizontal link to 90 meters, leaving 10 meters for patch cords and equipment cords in the channel.

Question 5

Which ANSI/TIA standard governs the installation of commercial building telecommunications cabling?

Accepted Answer

ANSI/TIA-568

Answer

ANSI/TIA-568 is the primary standard defining cabling components, transmission performance, and installation requirements for commercial buildings.
