Cabling and Technology Specifications
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
Table 3. Cabling Specifications
Twisted-pair copper
