I have 2960 and 3560 switch. The first link between them is using GLC-LH-SM. I want to have second link using GLC-BX-U. Is it possible to use two different SFP transceiver like that? I think it shouldn't be a problem, but need expert's advice.

Thank you.

You can mix different SFPs in the same chassis; just like you can run different port speeds on a switch.

You cannot run these particular SFPs links over the same fibers. You will need a different fiber for the new link.

One note: The single fiber application needs the GLC-BX-U and GLC-BX-D SFPs.
