I've got a 3750 switch stack that I need to connect via single mode fiber to a Hirschmann switch (yuck). Anyways, the Hirshmann supports only 100Mbit fiber, where the only SFP module (GLC-LH-SM=) for the 3750 that supports single mode fiber is a 1000Mbit. If both ends are set to auto negotiate, will the 1000Mbit side negotiate at 100Mbit or is it 1000 only? I've seen many different answerrs and would hope to get some clarification from someone here. Looking for a solution that will quickly resolve a problem!

have a look at table-7 in this link:
OK, so thanks everyone for the feedback. I went with the BlackBox media convertor. Its a 6 slot managed chassis and I bought the necessary single mode fiber to UTP modules that I needed. Hopefully this will do the trick!
