distance for a fiber between two Switch CRS305-1G-4S+IN

Hi everyone, what is the maximum distance for a fiber between two Switch CRS305-1G-4S+IN to reach 10G.

I think it depends your transceiver. 10G LR can reach 10km. 10G SR can reach about 300 meters.

also there is affordable sfp+ modules up to 80 kilometer available in the market

It depends on your fiber type (single mode? multi-mode?) and the transceiver module. The CRS305 doesn’t really impact the equation.
