Differentiation Copper and Fiber SFP

Is there a command to verify if a particular interface has a copper or fiber SFP? The "show net interface all" shows the Media type, but how to identify if it is a copper or a fiber connection?

 

For example If media type is 1000T-FD - Does the 'T' refer to copper? If media type is 10000SR-FD - Does the 'SR' refer to fiber multimode?

 

Is this interpretation right?

    The letters actually refer to the IEEE standard - you can find a list here for 10GB, and here for 1gbps.

     

    10000SR is 'short range' multi mode fibre, and 1000T is twisted pair.

     

    For completeness, "FD" refers to Full Duplex.
