Assuming the OSA-3 is a SR (short wave or reach) you can use multimode
50µ (aqua) cable for a distance of about 900ft. I am going through this
now. There is a single mode option (If I remember correctly), but
results in a shorter length. The 9µ core is pretty much standard for 50µ
single or multimode. The difference is cladding and protective wrap.
62.5µ is a bit bigger, orange, and used almost exclusively for ESCON.
Tons of stuff on the web; I found most of it via Google. Good luck, and
contact me off list if you need additional information, I think I can
find it somewhere.

Two Issues.
First, I've been tasked to procure the correct cables for a OSA-Express3
(feature code 3370 on a 2098).
The only specification I can find is '9 micron single mode fiber'. I'm having
trouble relating that specification to any verbiage on the cables or their
packaging. Can any one point me to a Rosetta Stone to translate the various
markings?
This sounds an awful lot like a standard long wave FICON cable.
Are these, in fact, one and the same? If so, can someone point me a definitive
IBM source? (This will be a mission critical application and management wants
'works for sure' rather than 'should work').
Second, the specific mission is to interconnect two 2098's. We could use a
switch (but that's a complicated solution) or we could use a 'cross over'
cable. I am thinking that all I have to do is swap the polarity of one end of
the fiber cable and I'm there. Anyone that has actually done this and have it
in high volume production? (Please, no speculation).
Thanks!!
