They are operationally identical and can be interchanged with no problems - the only difference is that the SFP-GE-T conforms to NEBS Level 3 and the GLC-T doesn't. (Well, I think the SFP-GE-T costs a bit more too..)

HTH - plz rate useful posts (not just mine!)

I'll also add that the SFP-GE-T is a little bit more expensive...maybe $40 more (retail) but it works in switches or routers like the ASR while the GLC-T is for switches only. I learned the hard way.

What happens when you put a GLC-T into a router?

Does it give you some sort of error message?
