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




Chris,

I made a presentation at the September '99 interim meeting titled "10GbE Implementation Architectures".  On page 4 I gave a list of
different implementation environments for 10GbE.  You might take a look at it.  One implementation that I did not include, which I
should have, was "clustered systems".  Clustered systems, servers or routers (data switches) from the same vendor that are
interconnected with common process sharing.  These systems will use 10GbE at distances less than 100m, most likely with proprietary
interfaces.

From my experience and talking to large customers and our own network out-sourcing people, I have come to the personal conclusion
that there is a potential large market for a LAN only PHY at 100 meters or less.  Most, if not all, of these will be greenfield
upgrade installations, not necessarily replacement upgrades.  The need for short reach 10GbE between systems from the same vendors
is very high in the Internet and large Enterprise networking environments.  While a common standard for this would be very
beneficial, I have a feeling that there are several vendors with proprietary solutions already in process.  The customer base will
get what they need, even if it is not standardized by IEEE.  OIF is also looking at this issue.

Thank you,
Roy Bynum
