[10GBASE-T] The channel model
I would like to propose the following channel and noise model. Then we
can work together to come up with a model that all of us agree on.
1. Channel insertion loss model: refer to the RLCG model on page 47 of
T1E1.4/2000-002R6. Then calibrate the insertion loss (100m) at 100MHz to
21dB for CAT-6 and 24dB for CAT-5/5E.
2. NEXT model: ~f^(1.5)n^(0.6) where n is number of disturbers. In our
case, n=3. Then calibrate the NEXT at 100MHz to -31dB for CAT-5E and -40dB
for CAT-6.
3. ELFEXT model: ~f^(2)n^(0.6) where n is number of disturbers. In our
case, n=3. Then calibrate the ELFEXT (100m) at 100MHz to -19dB for CAT-5E
and -24dB for CAT-6.
4. ANEXT model:
CAT-5E: max[-65, -38+15log10(f/1e8)] dB
CAT-6: max[-65, -41+15log10(f/1e8)] dB
5: Tranformer model: please contribute
