Anybody knows if Cisco 40G->10G breakout cable will step down to 1G?

Hello,

It looks like I will need to connect 1G-only device (fiber) to Cisco 9236c switch which has QSFP ports only.

I know that CVR-QSFP-SFP10G will work for this, but I don't have them in stock.

So my question is - do I need to rush order this adapter, or do you know if 40G QSFP with breakout cable would be able to work at 1G with the end device?

Thanks!
