So basically you are protected for your OPO-FRA-SFO connection, but boy that is tight from a Schengen flight to Non-Schengen and involving US destination with all those extra security precautions.
You better hope your flight is on time and be quick on your feet and even then this is a tough connection to make in the allocated time in FRA in my book. Good luck.
