I concur.  I have also used CWDM and DWDM optics and they are fine.  I have had one QSFP+ optic go bad.

Some we have ad running for 4+ years.  We have done very little with their SFP+ equipment, really only testing and a few lower priority links.

Say an Adtran, Cisco, Juniper, HP SFP is rated from -3dB to -8 db (all units I have used them with), the equivalent FS direct SFP we have seen as hot as 3dB and as weak as -15dB.  These extremes are fairly rare but we have still seen them.

With WDM SFP power consistency was important so we did not play much with it, granted most of the SFPs I am purchasing are in the $10-$25 range so take the extremes with a grain of salt.
