Re: [10GMMF] Customer Issues with LRM
All,
I just got back from PR briefings in Europe and now
finally got a chance to read Bruce's requests.
It's important to heed Bruce's requests and as one
of your potential customer as well, it's critical
that LRM must support 300m for 62.5 and 50 micron
(aka, existing FDDI-grade fiber).
Not supporting these requirements (Bruce's request),
means saying good-bye to a large portion of the
market. Of course, it also means that those vendors
that meet Bruce's requirements have more
opportunities than those that don't.
