You're looking for SOA at 1300nm, like https://www.fs.com/uk/products/69350.html
Getting much more power out of a SOA than a -ZR QSFP28 is pretty hard, though they could be used for non-OEO re-generation in the middle if practical in your topology.
There does also exist a PDFA. Same concept, different dopant in the fiber. They are...expensive. However, you can get a crazy amount of power out of them, and they're available with a lower noise floor than SOAs seem to be, as well. If you really want to make that 80-100km link at 1310nm and without going coherent, they are a potential option. When I inquired with a manufacturer/rep (what appears to be the only one in the world), it was almost as expensive as a coherent transponder on both ends.
