Hi,
Has anybody heard of a standard specification for fibers called
170003-GF. Apparently we mention it in one of our DecConcentrator 500
documents. Does anybody have any information on the spec??
Thanks
Rich

The document in question is likely to be the internal Digital
specification for single-mode optical fibers. The SMF described is the
standard dispersion-unshifted variety that is available from most fiebr
vendors. I can pull together the pertinent details, but I think if you
do a dir/title=single, you'll find the details.

Thanks Dick for the info,
The spec in question is 170003-GS the customer says and can be found in
Multimode option card installation for the DecConcentrator 500' manual
on page A-2. Unfortunately I haven't got this manual. So it seems
likely it is a spec for multimode fibers???
Got any ideas where this sepc might be kept??
Sorry to be a pain

We wrote 2 General Specifications for Optical Fibers - one for
multimode and one for single-mode. The spec numbers are:
17-10003-GS Optical Fiber, Dispersion Un-shifted Single-mode
17-10002-GS Optical Fiber, 62.5/125 micron, 0.275 NA, Graded
Index
These documents do not seem to have been loaded into the new CIMS
database. I will continue to seek out how they can be obtained.
I have extracted the pertinent details, if that will help. The specs
were written to meet the requirements of the FDDI PMD documents. Most
cable and fiber vendors will understand if their customers ask for FDDI
grade optical cable.
The DECconcentrator 500 had single-mode options as well as multimode
options, so your customer could use either.
Let me know if you need the specification details.

Thanks Dick for all your help on this one,
Could you possibly mail me the both fiber specs.
Thanks again,
Rich
