SFP - Need help how to set it up

Hello all,

I bought a SFP module from AliExpress and it was cheap. I don’t have experience in dealing with SFP. I suppose it’s straightforward. I plugged it in and tried with my home fibre broadband, nothing works. I’m from Singapore. Can somebody help me? Many thanks!

I’ve attached the picture of the SFP module.

Which TOS version has this been tried with TOS3.x | 4.x? Does it not work with with either TOS branch or only one not the other? Also which hardware (version) has the module been plugged into?

Also look into the system logs for any error/issue reported pertinent to operation of the module.
