Hi @David-TP 

I read in a different post you stated that the Deco BE 85 SFP+ port is compatible with 1G optical transreceiver and that the following models below have been tested compatible.

However I notice that the TL-SM311LM multi-mode module isn't listed. Does this mean this module isn't compatible? Could the engineer perform a test with this module to verify if it works as I have need for a multi-mode module over LAN.

TL-SM311LSv4

TL-SM321Av3

TL-SM321Bv3

TL-SM321A-2v1

TL-SM321B-2v1

TL-SM311LSv4.20

TL-SM321Av3.20

TL-SM321Bv3.20

TL-SM321A-2v1.20

TL-SM321B-2v1.20

Much thanks
