Note on 1000BASE-T Cable Requirements. The Category 5 networking cables

that work for 100BASE-TX connections should also work for 1000BASE-T, as long

as all four-pairs are connected. But, for the most robust connections, you should use

cabling that complies with the Category 5e specifications, as described in Addendum

5 to the TIA-568-A standard (ANSI/TIA/EIA-568-A-5).

Because of the increased speed provided by 1000BASE-T (Gigabit-T), network cable

quality is more important than for either 10BASE-T or 100BASE-TX. Cabling plants

being used to carry 1000BASE-T networking must comply with the IEEE 802.3ab

standards. In particular, the cabling must pass tests for Attenuation, Near-End

Crosstalk (NEXT), and Far-End Crosstalk (FEXT). Additionally, unlike the cables

for 100BASE-TX, the 1000BASE-T cables must pass tests for Equal-Level Far-End

Crosstalk (ELFEXT) and Return Loss.

When testing your cabling, be sure to include the patch cables that connect the switch

and the other end devices to the patch panels on your site. The patch cables are

frequently overlooked when testing cable. The patch cables must also comply with

the cabling standards.
