RE: PMD discussion


I always appreciate your valuable inputs from your actual, broad market
experience.  This one is no differences.

I agree with you there are overlaps in 5-PMDs, shorter is better, and this
complex issue needs inputs of all different reasoning.  We have to keep
discussing to narrow the differences.

One thing I noticed from your earlier comments that you need short jumpers
(VSR, below 100 meter), but you can handle it without standardization may
not be a good suggestion for the whole industry.  For the whole industry and
market, we should standardize all PMDs within IEEE 802.3ae specification
without exception.

Multiple options confuse the market when they overlap and the set of 5
options contains substantial overlap.

It is legitimate for informed people to disagree on complex issues and for
us to have difficulty converging on the short list of PMDs.

But everyone should be absolutely clear that the shorter the list is the
better both for market growth and for ease of completing the specification.
