What's the difference between SKU 10311 and 40GB-CO.5-QSFP

I see both devices listed on the X450 datasheet. I am trying to figure out the difference and which one is the correct one for stacking on the X450.

I think the only difference is manufacturer. Both are supported and should work with stacking on the X450-G2. The list price on both of them is the same as well.
