RE: [10GBASE-T] clarification on voltage level

The shielding requirement comment is only in regard to CX4, not
10Gbase-T, sorry. The cable balance comment holds.

We will need more information on cable balance and shielding to answer
this question. It is not a simple calculation of pp voltage to FCC
emission levels, but related to differential to common mode conversion
in the cable and integrity of the grounding of the cable to the MDI.

Can anybody who is familiar with FCC requirement give a careful
calculation on the highest possible voltage and launch power that meet
the FCC regulation.
