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.

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,
Brad
