I’m stringing aerial fibre between poles for about 1km. Along the way, I’d like to install security cameras. Each pole has power (347V, with 120V 50kVA control transformers), so I have capacity to power the switches.
The only solution I’ve found, so far, is to use a single copper-fibre media converter AND a PoE media converter with dual Ethernet ports and a single SFP port. The PoE port can power the camera and the second is connected to the single-port media converter.

Obviously, you’ll need an IP66 enclosure, and separate power supply, which is added expense, and added labor to your project.
There are some larger units out there, already integrated into an IP66 enclosure with power supply. . .

Definitely larger than you need, but it’s a plug-and-play solution.
Caveats: I can’t speak to the quality of any of these devices.
