Mellanox ConnectX-3 Pro QSFP to SFP+

[fossxplorer]

Is it possible to get 10GbE through something like an QSFP to SFP+ adapter?
Will this work with a Mellanox ConnectX-3 Pro https://www.aliexpress.com/item/1005003744281003.html?

I've tried a QSFP to 4x SFP+ breakout cable and it doesn't work at all.
I'm using one of the Hasivo 2.5G and 10G switches tested on STH to connect the other end of the SFP+.

the qsa adapter works with normal cx-3 and cx-4 so I assume that it will also work the cx-3 pro cards

connectx3 won't let you split the QSFP to 4x SFP+. that needs to be done on the switch with these.
however 1 of the SPF+ should work fine, and the other 3 won't.

Thanks @i386 and @cev!
I've ordered an QSPF to SPF+ adapter from AliE, will take some time to arrive.
I've also based on @cev 's suggestion tried all the 4 SPF+ splits into the Hasivo 10G port, can't get a link established.
