Note on 1000BASE-T Cable Requirements
The Category 5 networking cables that work for 100BASE-TX connections also work for 1000BASE-T, as long
as all four-pairs are connected. But, for the most robust connections, use cabling that complies with the
Category 5e specifications. This specification is 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.
Note on HPE Smart Rate 2.5 Gb/s Cable Requirements
The 2.5 Gb/s Smart Rate operates on cable installations that are designed to support 1000BASE-T
operation. The cabling installation must meet the 1000BASE-T link segment characteristics described in IEEE
802.3-2012. The installation must also meet the Category 5e or Class D limits described in the ANSI/TIA/EIA
568-C.2 and ISO/IEC 11801 standards, respectively.
Note on HPE Smart Rate 5Gb/s Cable Requirements
The 5 Gb/s Smart Rate operates on most Category 5e and Category 6 cable installations. Category 5e or
Class D installations must meet the ANSI/TIA/EIA 568-C.2 or ISO/IEC 11801 transmission parameter limits
extended to 200MHz. Category 6 or Class E installations must meet their respective transmission parameter
limits as described in ANSI/TIA/EIA 568-C.2 or ISO/IEC 11801.
Also, to transmission performance, 5 Gb/s Smart Rate can be sensitive to alien noise. Such noise can come
from either nearby cables or background noise from the environment. Therefore, cabling must additionally
be tested for Alien Near-End Crosstalk (ANEXT) and Alien Equal-Level-Far-End Crosstalk (AELFEXT).
Depending on the cabling installation, the magnitude of alien crosstalk may further limit the maximum
supported cabling distance.
Hewlett Packard Enterprise recommends doing cable dressing carefully and in compliance with
recommendations in the TIA TSB-155-A and ISO/IEC TR-24750.
Direct attach cables One-piece devices consisting of a cable with SFP+
connectors permanently attached to each end,
complying with SFF 8431 SFP+ specifications.

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.
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.
