GLC / GLX What's the difference?

[gdshaffer]

Could someone enlighten me? I am trying to buy a GLC-SX-MM SFP module via Fed Stock, and I keep getting a GLX-SX-MM. What is the difference between these two part numbers? I can't find it on the Cisco Web site and eve a search of Google comes up relatively fruitless! Is the GLX compatible with my 3750G-24PS switch? Thanks!

I've never heard of "GLX" before.  It's either a type-o or a 3rd party and may not be supported.  Look at the link below.

I had never heard of a "GLX" before either.  I am at the mercy of a 3rd party contractor hired by the Gov't to purchase material fot this project. I guess I will have to wait and see what I get. I specified GLC-SX-MM SFPs... Good Grief...
