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 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.
The Auto-MDIX Feature:
In the default configuration, “Auto”, the fixed 10/100/1000BASE-T ports on the
switches all automatically detect the type of port on the connected device and
operate as either an MDI or MDI-X port, whichever is appropriate. So for any
connection, either a straight-through or crossover twisted-pair cable can be
used.

1000 Mbps Operation Category 5, 100-ohm 4-pair UTP or STP cable, complying with IEEE
802.3ab 1000BASE-T specifications—Category 5e or better is
recommended. See 1000BASE-T Cable Requirements below.
