RE: [10GBASE-T] Technical feasibility: survey

Title: Technical feasibility: survey
1) No
2) No
In general, 2 only works in conjunction with the following:
- Set limits/technical feasibility target for emissions
- Bound the BW for coding (based on previous work from the committee)
- Set PAM level, ensure emissions capability (BALANCE is critical for transformers and driver, any common mode noise increases as F goes up in transmission BW, and design of both circuit grounding, transformer, center tap, winding affect performance, common mode to differential conversion and vice/versa occur in the cable plant and contribute to meeting emissions, which up to this point has not been clearly spelled out until cable plant is settled). The increased output levels for each step may be needed to mitigate ANEXT S/N at receiver to guarantee the target BER
- Verify Receiver can work to these requirements with the projected technology for Sample/hold parallel ADC architecture or direct conversion converters. "Works" and "WATTS" are tied very closely on this point for technical feasibility, now and 3 years from now.

Subject: [10GBASE-T] Technical feasibility: survey

I would like to take a quick survey of the experts:
1) Do you believe that 10 Gigabit Ethernet over 100m on Cat7 is not technically feasible?
2) Do you believe that the power required for 10 Gigabit Ethernet over 100m on Cat7 make it not technically feasible?
3) If you said "yes" to 1) or 2), then what do you believe needs to be done to satisfy technical feasibility for the 10GBASE-T Study Group?

Thank you,

Chair, 10GBASE-T Study Group
