If you read the datasheets, they say a "guaranteed optical link budget" of 10d
Yeah, I wondered the same thing.

Yeah, I get that the distance marking is not real, and that's why I was
looking at the light budget. Initially, I was looking because I have 20km
transceivers on hand and a path that's something like 27km. I was trying to
determine if it was even worth trying

The 20k 40k 80k definition on these is marketing fluff. you have to look
at the actual specifications and calculate it to your network. There is
a difference in quality though. The shorter distance lower priced ones

Help me understand this:
20km transceiver (SFP+ CWDM)
https://www.fs.com/products/38707.html?now_cid=65
Max Tx power +6dBm. Rx sensitivity -14.4dBm. So a power budget of 20.4dB
40km transceiver (SFP+ CWDM
https://www.fs.com/products/15385.html?now_cid=65
Max Tx power +5dBm. Rx sensitivity -15d
Different frequency light has different loss per km.
