A Pair of Gigabit SFP to RJ45 Converter, Fiber to Ethernet Media Converter with SFP Slot (Without Module), Plug & Play, 10/100/1000 Base-T Compatible, Auto-Negotiation & Jumbo Frame Support

This sounds almost identical to my dad's workshop setup. Currently, we have an Asus AiMesh router sitting in the shop window, with wireless backhaul to the other routers in the house, and rebroadcasting Wi-Fi inside the shop. If I move the router to either side of the window, behind the metal siding, it gets no signal at all. I'm working on a plan to run fiber (something like https://www.amazon.com/gp/product/B0C9Y6PWYC/ ) out to the shop, so the router can be placed in a more central location instead of needing to sit in the window for backhaul. I have a pair of media converters ( https://www.amazon.com/dp/B0D1CK56VR/ ) that I'm not using, so the basic plan is to just convert the 1GbE in the house to fiber, run it across the yard, then convert it back to 1GbE to plug into the Asus out in the shop. Fiber is preferred over copper in these situations because it eliminates ground issues between the two buildings and is immune to lightning issues outside.
