Collect model of installed transceivers

Is there a command that can collect the models of the transceivers installed on a check point appliance?
I have a use case where I want to identify if the transceiver is SR or LR

It looks like ethtool -m is a native linux command that would do the job, but it looks unsupported on GAiA R7X.

I ran the command with the following syntax and my gw failed to recognize the command:
ethtool -m
