SFP+ AND SFP

Can I stick an SFP transceiver module in a SFP+ port in a Cisco Nexus 5K for example if I need to connect a fast ethernet switch with a 1 Gbps SFP uplink port in Huawei S9300? I saw this Nexus's ports are 1/10 Gbps.

Does it depend on a switch module or is there a general rule, that they should be compatible?

Yes, you can use an SFP in a 1/10G port to support a 1G connection.  You may need to use the "speed 1000" command.
