The data shows signal reduction at various dB levels. For a 20km setup, a 13dB attenuator would reduce it to 1km, while a 15dB attenuator would bring it down to 640 meters. This seems appropriate.

You don't need that. Don't overthink it. Here's all you need to get Gigabit to your outbuilding: 150m LC to LC SM2 Single Mode fiber Fiber to Copper media converter with 1000Base-LX SFP transceiver (2x) Run the fiber between buildings (inside a conduit), stick a media converter on each end. Boom, done. These should be equivalent: https://www.amazon.se/Good-Connections-L...B08JQJ1LLM https://www.amazon.se/glasfiberomvandlar...B08ZN8DNV5 If you want 10 Gigabit, you'll need switches with SFP+ ports and 10GBASE-LR SFP+ optics instead of the media converters. Other than that, the idea is the same.

Media converter priced at $29 (requires two units). Ethernet to SFP media converter available via the provided link. Transceivers cost $7 (two needed). LC Duplex connector, Multimode Fiber compatible with Cisco GLC-SX-MM, supports 1000BASE-SX at 850nm over 550m using OM2 and OM1. FDDI MMF option available for $8. Transceivers support OM2, OM1, OM3, and up to 10km distances. LC Duplex connector needed. Single Mode Fiber compatible with Cisco GLC-LH-SM, supports 1000BASE-LX/LH at 1310nm over 10km. Use 2 fibers for regular transceivers. BiDi transceivers exist; they utilize two wavelengths on one fiber—one for sending, another for receiving. Switching frequencies is required. Benefit: fiber may be more cost-effective initially, but future upgrades to 10G or 40G may need more expensive BiDi solutions. LC Duplex connectors recommended. Fiber length can be adjusted to reduce expenses. Customized patch cables offered for various transceiver types.

Observe that combining single-mode and multimode fibers with transceivers isn't possible—choose a single standard.

Also think about hiring a professional for wiring an outbuilding. I’m not sure about other countries, but in the UK this usually requires a new ground connection for the outbuilding since separate structures need different grounding. While some people try to do it themselves, it could be illegal, fail building codes, and might even affect your home insurance.
