What is an SFP and what is it used for?

Hello. I do mostly small business networking, nothing too enterprisey. Anyway I have a client who has just sent me a picture of some cables that he's been sent by another supplier, they are SFP+ Direct Attach Copper Cables, 1 meter in length.

I've Googled them and clearly it's a bit topic. But what I'm finding difficult is just to get a straight answer on what they're actually for, as in what is the use case. Not how they work, but why, what's situation where these things are useful? So I was hoping someone here could enlighten me. Thank you!
