Are they other alternative transceivers that someone has used to connect a CRS326-24S+2Q+RM - 40G QSFP+ port to a CRS504-4XQ-IN - 100G QSFP28 port with fiber directly using a 1x12 MTP/MPO Multimode cable other than the XQ+85MP01D? The XQ+85MP01D is on the compatibility list:

I am aware that it will only do 40gb but I am having a hard time finding 100G QSFP2 transceivers that also do 40G 
Anyone had any luck testing/implementing other transceivers?
Any suggestions are appreciated.
