Re: [10GMMF] Feature Request for 10MMF
I did discuss with David Cunningham last evening and we'll be looking into the feasibility considerations, product timing and coverage aspects with this. We will also be revisiting the -LX4 (products for which are shipping today) coverage considerations more rigorously than done earlier. Some of the parameters being discussed for the TP3 tests, based on some of the "worst-case" fibers may turn out to be too stringent for -LX4 to support as well.

To all LRMers
Sorry I could not make it to Portland. This is the last month of our fiscal
year and I am called by a higher power to focus on near term goals :)).
To echo Val's first point, we have been shipping -ER, -LR and -SR to
customers for some many months now. The relevant experience for the 300
meter goal is not comparisons to 1000BASE-SX at this point, but experience
with deployment of the shipping port types and talking to customers about
all the existing and potential 10GBASE- port types.
Customers are communicating a VERY strong requirement for 300 meters on
legacy and new MM fiber. To ignore this requirement is, at the very least,
to neglect the broad market potential criterion. You may not agree with
this requirement but I can tell you from personal experience it is the
expectation today from the customers who want spend money on 10 Gb Ethernet.
