Question 1

What is the maximum horizontal cable distance from the telecommunications room to the work area outlet per TIA-568?

Accepted Answer

90 meters (295 ft)

Answer

TIA-568 specifies a maximum horizontal cable run of 90 meters (295 ft), leaving 10 meters for patch and equipment cords within the 100-meter channel limit.

Question 2

Which wire map fault occurs when a wire is connected to different pins at each end of the cable?

Accepted Answer

Reversed pair

Answer

A reversed pair (also called transposed pair) occurs when the two wires of a pair are connected to opposite pins at one end compared to the other.

Question 3

Per TIA-568, what is the minimum number of telecommunications outlets required per work area?

Accepted Answer

2 outlets

Answer

TIA-568 requires a minimum of two telecommunications outlets per work area to support both voice and data services.

Question 4

What installation practice helps minimize alien crosstalk between adjacent Category 6A cables?

Accepted Answer

Maintaining manufacturer-specified spacing or using shielded cable

Answer

Maintaining manufacturer-specified spacing between Cat 6A cables or using F/UTP (shielded) cable significantly reduces alien crosstalk.

Question 5

Which standard governs pathways and spaces for telecommunications in commercial buildings?

Accepted Answer
