What is the maximum length specification for unshielded Cat6 cable when used in a 10GBASE-T environment?

What is the maximum length specification for unshielded Cat6 cable when used in a 10GBASE-T environment?

  • 328 ft (100m)
  • 100 ft (30M)
  • 180 ft (55m)
  • 365 ft (112m)

What is the maximum length specification for unshielded Cat6 cable when used in a 10GBASE-T environment?

EXPLANATION

Category 6 cable (Cat 6), is a standardized twisted pair cable for Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards.

Cat 6 has to meet more stringent specifications for crosstalk and system noise than Cat 5 and Cat 5e. The cable standard specifies performance of up to 250 MHz, compared to 100 MHz for Cat 5 and Cat 5e.

Whereas Category 6 cable has a reduced maximum length of 55 meters when used for 10GBASE-T, Category 6A cable is characterized to 500 MHz and has improved alien crosstalk characteristics, allowing 10GBASE-T to be run for the same 100 meter maximum distance as previous Ethernet variants.
