Question 1

What does 'return loss' measure in a copper cabling channel?

Accepted Answer

The signal that returns to the source due to impedance mismatches

Answer

Return loss measures the ratio of the reflected signal to the incident signal, caused by impedance mismatches along the cabling channel.

Question 2

In BICSI copper cabling, what is the maximum frequency specified for Category 6A channel performance testing?

Accepted Answer

500 MHz

Answer

Category 6A channel performance is specified and tested up to 500 MHz per ANSI/TIA-568-C.2.

Question 3

Which BICSI-recommended practice applies when copper cabling must cross an EMI source such as a fluorescent light ballast?

Accepted Answer

Cross at a 90-degree angle and minimize parallel routing near the source

Answer

BICSI recommends crossing EMI sources at a 90-degree angle and minimizing parallel routing near the source to reduce electromagnetic interference coupling.

Question 4

What is the minimum Category of twisted-pair cabling required to support PoE Type 4 (IEEE 802.3bt, 90W) per TIA recommendations?

Accepted Answer

Category 6

Answer

TIA recommends Category 6 or higher cabling for PoE Type 4 applications to handle the higher current and heat generated by 90W PoE systems.

Question 5

In a BICSI field test report for copper cabling, what does 'FAIL*' (with an asterisk) typically indicate?

Accepted Answer

The result is within the measurement uncertainty margin (a marginal pass or fail)

Answer

A FAIL* (asterisk) result indicates that the measurement is within the instrument's measurement uncertainty margin, meaning the result is marginal and could be a pass or fail depending on actual conditions.
