The 'Cisco Optics-to-Device Compatibility Matrix' located at https://tmgmatrix.cisco.com/ may help you to verify compatibility of the SFP you are trying to use with your specific switch model.

Lots and lots (and lots) of possibilities. Most common issues are something is defective, something isn't supported, something is misconfigured.
If you provide the information requested by the other posters, possibly we can narrow possibilities to only lots and lots.
If problem isn't obvious, such as whatever isn't supported, troubleshooting often requires comparing to other working similar solutions, such as the does SFP port work with another SFP transceiver, does SFP transceiver work in another SFP port, etc.
