Have you looked at the IBM Redbook: IBM System z Connectivity Handbook SG24-5444-11
- Tim -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Doug Fuerst Sent: Tuesday, February 01, 2011 12:08 PM To: [email protected] Subject: Re: Fiber Cables 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.
