Sanjay,
TIA TR42 has initiated a project (PN-3-0134) investigating balanced cabling performance up to 625 MHz for
both TIA category 6 and category 5e cabling for 10GBASE-T applications (see scope below).
Measurement data will be shared directly with IEEE 802.3. 10GBASE-T Task Force as it becomes available.
Applicable category 6 data and guidelines from the study will be presented in a new
Technical Systems Bulletin or Engineering Publication.
Regards,

Scope: TIA TR42 - Project PN-3-0134:
=================================================================
Project PN-3-0134: Investigation of balanced cabling performance up to 625 MHz for
both TIA category 6 and category 5e cabling for 10GBASE-T applications.
The project consists of a study of measurements of category 5e and category 6
cabling transmission performance and alien cross-talk up to frequencies of 625 MHz,
including the relationship of transmission parameters and alien crosstalk and their
field testing and mitigation.
Applicable category 6 data and guidelines from the study will be presented in a new
Technical Systems Bulletin or Engineering Publication. Category 5e and category 6
measurement data will be shared directly with IEEE 802.3. 10GBASE-T Task Force
as it becomes available.

We have four channel models defined from the March 2004 plenary meeting.
For detailed phy performance simulations, we will need sample channel data that complies with these models.
We will greatly appreciate it if any task force participants can provide full matrix (4x4) channel data. This would ideally include:
a) Insertion loss data on each of four pairs - real and imaginary
b) Near end crosstalk coupling (6 unique pair-combinations) - real and imaginary
c) Far end crosstalk coupling (6 unique pair-combinations) - real and imaginary
d) Four unique echo transfer functions (one for each pair) - real and imaginary
This can be obtained by measurements on actual cable and then scaling to meet the specified channel models.
Any cable companies volunteering to provide this data?
This data has some of the items listed above but not all. It does, however, provide enough to get some sense of performance.
