Copper Installation Flashcards

What is the maximum allowable pair untwist at a termination point for Category 6 copper cabling?

Answer: 1/4 inch (6 mm)

ANSI/TIA-568 limits untwisting to no more than 1/4 inch (6 mm) at terminations to maintain crosstalk performance.

Which tool is used to properly seat an RJ-45 plug onto a solid copper conductor?

Answer: Crimping tool

A crimping tool is used to mechanically seat and lock the RJ-45 modular plug onto the cable conductors.

What does 'pulling tension' refer to when installing copper cable?

Answer: The maximum tensile load allowed during cable pull

Pulling tension is the maximum force that can be applied to a cable during installation without damaging its electrical or mechanical characteristics.

Which wiring standard uses the color sequence White/Orange, Orange, White/Green, Blue, White/Blue, Green, White/Brown, Brown?

Answer: T568B

T568B is the wiring standard with White/Orange on pin 1, which is the most commonly used standard in commercial US installations.

What is the minimum bend radius for a 4-pair UTP cable during installation (under tension)?

Answer: 8 times the cable diameter

Under tension during a pull, UTP cable must maintain a minimum bend radius of 8 times the cable's outer diameter.

What test parameter measures the signal loss experienced as a signal travels along a copper cable?

Answer: Insertion loss (attenuation)

Insertion loss (also called attenuation) measures the reduction in signal strength as it travels from one end of the cable to the other.

When installing copper cable through a fire-rated wall, what is required?

Answer: Apply firestop material to seal the penetration

Any penetration through a fire-rated barrier must be sealed with approved firestop material to restore the fire rating of the assembly.
