Cabling and Technology Information
Note Incorrectly wired cabling is the most common cause of problems for LAN
communications. HP ProCurve recommends that you work with a qualified
LAN cable installer for assistance with your cabling requirements.
Cabling specifications
Table A-2.
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
Twisted-pair copper 10 Mbps Operation 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.
100 Mbps Operation Category 5, 100-ohm UTP or STP cable, complying with IEEE
802.3u 100Base-TX specifications.
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 note on 1000Base-T Cable Requirements
below.
Multimode fiber 62.5/125 μm or 50/125 μm (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
respectively.

Single mode fiber 9/125 μm (core/cladding) diameter, low metal content fiber-optic
cables, complying with the ITU-T G.652 and
ISO/IEC 793-2 Type B1 standards.

A mode conditioning patch cord may be needed for some Gigabit-LX installations. See “Mode Conditioning Patch Cord”
on page A-4 for more information.
