RCDD (RCDD): Mastering Telecommunications Standards 2

Question 1

According to ANSI/TIA-568, what is the maximum allowable channel insertion loss for Category 6A cabling at 500 MHz?

Accepted Answer

47.8 dB

Answer

ANSI/TIA-568 specifies a maximum channel insertion loss of 47.8 dB for Category 6A at 500 MHz.

Question 2

Which standard defines the requirements for telecommunications pathways and spaces in commercial buildings?

Accepted Answer

ANSI/TIA-569

Answer

ANSI/TIA-569 covers telecommunications pathways and spaces, including conduit, cable tray, and room requirements.

Question 3

What does the BICSI TDMM define as the maximum recommended distance for a horizontal cable run in a standard structured cabling design?

Accepted Answer

90 meters

Answer

The permanent link maximum is 90 meters for horizontal cabling, with 10 meters reserved for patch cords and equipment cables to stay within the 100 m channel limit.

Question 4

In the context of TIA-568, what parameter measures the unwanted signal coupling from one pair to another at the far end of a cable?

Accepted Answer

ELFEXT

Answer

ELFEXT (Equal Level Far-End Crosstalk) measures pair-to-pair crosstalk at the far end of a cable, normalized for insertion loss.

Question 5

Which ISO/IEC standard is the international equivalent to ANSI/TIA-568 for generic cabling for customer premises?

Accepted Answer

ISO/IEC 11801

Answer

ISO/IEC 11801 is the international standard for generic cabling for customer premises, paralleling ANSI/TIA-568.
