RE: what's next ?




Comments:

I agree that we should standardize the technologies for interoperability,
but not to get into the product interoperability issues.  There are so many
different form factors, and connectors, which even the GbE and Fibre Channel
market can not get consensus.  They leave it to the users, and market to
determine their options.   We may be dragged into a unnecessary delay, if we
try to determine those fro 10GbE.

Jonathan,

I would assume that 802.3ae would do the same as 802.3z, and NOT specify
conectors. The models that we work from are sufficient to determine the
optical tables, since most of that work was done in 802.3z, and I would
not anticipate new optical test procedures, though there might be some
associated with launch condition. That work is nearing completion. As far
as the jitter goes, that one may require some additional work, but I   think
it any MMF solution (I assume that this is a must have for   802.3ae... as
dictated by the PAR) would require some amount of work.

Dan,

If we are successful in adding the necessary PMD(s) to the baseline
proposal
during the September Interim Meeting, I see no reason why this detour
should
cause any modification in the overall schedule.

Structurally, adding a Serial PMD will end up as a "column addition" to
the
Serial PMD clause (yes, I know, like with clause 38, we might actually
have
new tables). This level of change should be pretty transparent.   Especially
since we already know the specifications for the tables. Right?

For non-serial, PMD proposals, it would certainly help if any September
presentation came equipped with a "Draft 1.0 equivalent."

I am more concerned with a few details that we haven't gotten to yet:
1. What is the connector on the media going to be? SC/LC/MT/Other?
2. What new optical test methods are required?
3. Can we lock down the jitter specifications and measurement (XAUI,   SUPI,
TP2/TP3)?
etc.
