Question 1

What conductor gauge is specified for standard Cat5e/Cat6 horizontal UTP cabling?

Accepted Answer

24 AWG solid copper

Answer

TIA-568 specifies 24 AWG (American Wire Gauge) solid copper conductors for horizontal UTP cable runs.

Question 2

Which bonding method is required when terminating shielded twisted pair (STP) cable to maintain a continuous ground path?

Accepted Answer

The cable shield must be bonded to the jack or panel ground at both ends of the link

Answer

STP/FTP cable shields must be bonded at both ends to provide a complete ground return path; a shield grounded only at one end acts as an antenna rather than a shield.

Question 3

What is the maximum amount of untwisting allowed when terminating a Cat6 conductor pair to a 110-style IDC jack?

Accepted Answer

0.5 inches (13 mm)

Answer

TIA-568 limits pair untwisting during termination to 0.5 inches (13 mm) for Cat6 to preserve the cable's crosstalk rejection characteristics.

Question 4

A technician must document a copper cabling installation per ANSI/TIA-606. What information is minimally required for each cable record?

Accepted Answer

Cable identifier, both end locations, and media type

Answer

TIA-606 requires each cable record to include a unique identifier, the locations of both termination ends, and the cable type/media as minimum documentation.

Question 5

What is the primary reason Cat6A U/UTP cable has a significantly larger outer diameter than Cat6 UTP cable?

Accepted Answer

Thicker insulation and larger cable geometry are needed to reduce alien crosstalk (AXT) without a shield

Answer

Unshielded Cat6A achieves AXT suppression through increased pair separation provided by its larger cable body and internal geometry rather than a metallic shield.
