C9300 CVR-QSFP-SFP10G Compatible 40G QSFP+ to 10G SFP+ Adapter

[Chris.Mes]

We were trying to connect a C9500 with C9300 which has the2x 40Gbit Module.
But we needed 10Gbit/s for the uplink.
We bought "Cisco CVR-QSFP-SFP10G Compatible 40G QSFP+ to 10G SFP+ Adapter Converter Module" (not the original Cisco), the link was coming up, but absolutely no traffic was going over the connection (no ping, no cdp neighbor, etc.).
Will it work with original Cisco adapter?

 - It's a bit of a wrong question guess should be - why does it not work with a foreign adapter, for compatibility info's go here : https://tmgmatrix.cisco.com/
