RE: Subject: Survey of lengths of installed optical fiber cable

Yes, your "leap" appears to be accurate.  We feel that there is a large,
important space, i.e. VSR, which could benefit from 850nm serial.  I was not
participating in GbE during the development stage.  So I can't comment on
whether I'm bucking the basis for which GbE was developed under.  But, as
the cost ratio of GbE LX/SX was sufficient to justify the SX product, a
similar ratio is expected for 10Gb WWDM/850 Serial.

Picolight will be presenting at the Ottawa meeting in support of my

After looking at the distance objectives, and reading the reflector messages
on the issue of 100m 850nm PMD, is there anything that
you believe is missing?  I participated in the distance ad hoc last year and
the market for a very short reach PMD did not receive
much comment.  My memory may be faulty, but believe that most of the
emphasis was on distances that reflected the existing paradigm
in GbE which had just been completed.  I am making a "leap" here in that I
believe that you think that there may need to be a change
in the paradigm.  I believe I understand you to say that unlike the paradigm
that GbE was developed under, there is a major
potential market for very short reach (VSR) optics for 10GbE.   Am I

If you believe that a paradigm shift is needed, will you be presenting
anything next week?

Thank you,
Roy Bynum
