RE: Subject: Survey of lengths of installed optical fiber cable
Roy and All:
I agree with you. There are large demand on the 100 meter or less cables
within majority of computer installations. I myself experienced with many
major customers, who use jumper cables (short cables) to interconnect all
sizes of equipment being in the same cabinet, next each other, close one
another, or clustered. In fact, it is a commonsense (cost-effective, and
convenient), to realize the jumper cables (short cables) are used in
interconnecting huge numbers of short connections.
Regardless of a short cable being standardized or not, when users need them,
there are plenty of suppliers to fill the needs. As a result, we should
make sure to provide low-cost 100 meter, or shorter cables to industry.

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
