Hi,
At "site A" I have a 2955S-12 with a 100Base-LX(SM) uplink to "site B" over 800m SM fiber run. At "site B" I have a 3750G-12S. My question, Is there an SFP that will allow me to step down my 3750G Gig port down to 100mb over a SM fiber ?
GLC-GE-100FX - works only for MM fiber
GLC-FE-100FX - looks like it won't work in gig ports.
Thanks !!

No, nothing supported by Cisco.
Review the compatibility matrix

Thanks for the feedback. I just find it odd why Cisco would support 100mb MM and not SM links on the 3750 series.
