Difference between "MMD=" and "MMD++="?

[network4fun]

Hi,

I'm trying to figure out the difference between MMD= and MMD++= on Cisco SFPs.  Does anyone know what the ++ and = signify?  What is the difference? Also, do you have any links to a document stating so?  

I've Googled everywhere and I can't seem to find anything

This is for a product like this:

1000BASE-SX SFP XCVR Mod MMF 850NM DOM

GLC-SX-MMD++=

GLC-SX-MMD

SFP (mini-GBIC)

Networks

Thank you.

Have you found anything within Cisco documentation explicitly saying ++ means TAA compliant?   You provided a nice clue and unfortunately nothing official.
