I have a unmanaged TP-Link 8 port switch (TL-SG1210MP) that is going to connect to another unmanaged TP-Link switch (DS1018GM) with an sfp module (TL-SM321B V2). I am just trying to make sure this sfp will be compatible with both swtiches. Amazon says this sfp is compatible with all TP-Link products, but I cannot find a solid answer on TP-Link's websites. Is there someone that can give me a link to validate compatibility, or has experience with these switches?

Thanks!
