SFP to RJ45 later, based on my experience anyway. Also works on the SFP+ port. The only possible problem is when the hardware expects a certain speed, e.g. B. 10 Gbit/s, and it is connected to 1 Gbit/s. In this case you may need to set the speed manually in the hardware, but this option is not always available. Likely SFP is rarely used for anything other than 1GB, so problems are unlikely.
