According to ANSI/TIA-568, which cable category is the minimum required to support 10GBASE-T Ethernet over a 100-meter channel?

Accepted Answer

Category 6A

Answer

Category 6A is the minimum standard required to support 10GBASE-T at the full 100-meter channel distance due to its alien crosstalk (ANEXT) specifications.

Question 2

The ISO/IEC 11801 standard is most comparable to which US standard?

Accepted Answer

ANSI/TIA-568

Question 3

What NEC classification is required for cabling installed in a plenum air-handling space?

Accepted Answer

CMP (Plenum)

CMP-rated (Communications Multipurpose Plenum) cable is required in plenum spaces because it has low smoke and flame-spread characteristics.

Question 4

Under ANSI/TIA-568, a telecommunications outlet/connector (TO) must be installed no closer than what distance to a power outlet?

Accepted Answer

6 inches

Answer

ANSI/TIA-568 recommends at least 6 inches of separation between telecommunications outlets and power outlets to reduce interference.

Question 5
