Not sure if the right spot please redirect me if not. Looking for a fibreoptic (SL) to USB3 media converter in a small form factor. Any leads?

I already have one with gigabit ethernet but I want to try a new piece of hardware that requires USB 3 and needs to fit into a small space and have a temp rating of around 80°C. Or is their a work around for it?

Current unit has a foot print of W: 1.75” (44mm) x L: 2.25” (57mm) x H: 0.84” (21mm) I'd like something this size or smaller.
