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.
Category 3, 4 or 5, 100-ohm unshielded twisted-pair (UTP) or
shielded twisted-pair (STP) cable, complying with IEEE 802.3
10BASE-T specifications.
Category 5, 100-ohm UTP or STP cable, complying with IEEE
802.3u 100BASE-TX specifications.
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 note on 1000BASE-T Cable
Requirements below.
One-piece devices consisting of a cable with SFP+ connectors
permanently attached to each end, complying with SFF 8431
SFP+ specifications.
62.5/125 m or 50/125 m (core/cladding) diameter, low metal
content, graded index fiber-optic cables, complying with the
ITU-T G.651 and ISO/IEC 793-2 Type A1b or A1a standards
1
respectively.
9/125 m (core/cladding) diameter, low metal content fiber-
optic cables, complying with the ITU-T G.652 and
ISO/IEC 793-2 Type B1 standards.
