A White paper from HP exist:

For "normal" setup (not long distance) FC cable needs to be LC-LC Multimode 50/125u minimum OM3 in quality. You can buy original HP cable at premium price. We ended up buying OM4 cables from another vendor saving a fortune.
I would never buy other than original HP SFP Transcievers though mainly because of potential issues with warranty. (HP don't produce their SFPs but buy from different vendors)
You can look at the VC quickspecs to find the partnumbers
I would also recommend Reading the HP San reference guide
