I have an HP switch with an LC SX fiber GBIC.

Do you know, or think - please indicate - if that will work when connected to a ES‑48‑500W with a 10GTeck SFP SX GBIC?

Are you asking if the SFPs will work in the switch or if the SFPs will talk to each other? if you asking if they will talk to each other yes, It's still ethernet. As long as you are using the same type of fiber SFPs (or ones that will take SMF and MMF) and the correct speed and micron then they will work, that is unless you try something stupid like using a SMF run a few feet apart you will burn out the SFP.

But it is standards based and it is still just ethernet, the one side doesn't care what brand is on the other. It's the same as plunging a CAT5 Ethernet cable into dissimilar brands of switches.
