RE: [10GBASE-T] channel model




Xiaopeng

How are the calculations coming?  Are you using the models Chris sent out last week?

Bill

Bill,

Sure.  Once the common channel model (I only need the frequency domain
characteristics) is available, I can begin to work on it.

Would you be willing to sign up for technical feasibility based on an
optimal DFE calculation?

Bill,

I has no problem to use TIA or ISO based channel and noise model once it is
standardized.  My point is that even using the frequency-domain model we
can still give a quite good estimation of the practically achievable
distance at a throughtput of 10Gbps over CAT-5E or CAT-6 cables.

We believe, as George discussed in his part of the tutorial in Kauai, that
with an adequate amount of crosstalk cancellation, the throughput is
achievable.  The question then becomes can this level of cancellation be
practically achieved, hence, my interest in time domain models.

Until we get the models from the channel modeling Ad Hoc, we could argue
this point endlessly.  Until then, I still believe we should not use DSL
models, but, rather something from TIA 568b or ISO 11801.
