Cable Requirements for 1000BASE-T and
10/100BASE-TX Connections
This section provides details of the 1000BASE-T and 10/100BASE-TX cable
requirements when connecting to a Sun Fire B1600 blade system chassis.
5.3.1
1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T connections, providing that all four wire pairs are connected.
However, for all critical connections or any new cable installations, use
Category 5E (enhanced Category 5) cable. The Category 5E specification includes
test parameters that are only recommendations for Category 5. Therefore, the first
step in preparing existing Category 5 UTP cable for running 1000BASE-T is a simple
test of the cable installation to confirm that it complies with the IEEE 802.3ab
standards.
5.3.1.1
Cable Testing for Existing Category 5 Cable
Installed Category 5 UTP cables must pass tests for Attenuation, Near-End Crosstalk
(NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in
the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test
parameters for Return Loss, skew and Equal-Level Far-End Crosstalk (ELFEXT).
These tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The Additional
Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”
