RE: [802.3ae_Serial] Support for 10GFC
Tom,
Good idea. From the standpoint of return on development efforts,
10GFC is a low hanging fruit. The increase in power budget is
relatively small.
I hope the designers of XGXS and PCS will do a similar exercise. My
(unreliable) recollection is that apart from the increased 2% speed,
the only thing a designer has to make sure is that K28.2 and K28.6
are supported. Support for these two characters is required in
10GFC, but not in 802.3ae.
Regards,
Vipul

Folks - 10G Fibre channel intends to use 10G Ethernet PMDs but for a
rate that is 2% faster. For serial, this would mean 10.51875 Gbd;
for LX4, this would mean 3.1875 Gbd per lane.
As a modeling approximation, I modified cell C4 in
10GEPBud3_1_16a.xls to the FC rates. Margins stay positive for
all -S variants, but go negative for:
-0.05 dB for 1310 serial
-0.21 dB for LX4
Possibly any of these are within spreadsheet margin for error, but
is there willingness to increase the power budget to drive these
margins back positive?
