LR4 and weak ER4 (flexoptix were trying to get a 40km part out, only 25km has emerged so far) then you're into coherent stuff in a separate box (which per 100G doesn't cost a lot more than the ER4's) > I need stronger modules that can do more than 10 km without being > extremely expensive.

We use 1310 amplifiers for now, originally these http://www.hubersuhner.com/en/solutions/cube-optics/products/active-systems/metro-transport/soa-semiconductor-optical-amplifier-unit-c-250 but there is a fibrestore version too now https://www.fs.com/products/69350.html > Am I looking in the wrong place?
