NOTE:
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 controller and
other end devices to the patch panels on your site. The patch cables are frequently overlooked
when testing cable and they must also comply with the cabling standards.
