Building port channel (vpc) using different type QSFP modules

[Junwei Li]

We have 2 N9K switches , and want to add several FEX line cards (still N9K switches) via VPC , can I pick two different type QSFP modules:
QSFP-40G-SR4-S ( MMF,MPO12)
QSFP-40G-LR4-S (SMF,LC)

two build the port channel ?
Or can put simple like this : can ports using different QSFPs be aggregated to a VPC ?and be used as FEX linecard uplinks ?

Thanks.

Thanks

i do not see any issue here as long as the module supported.

i have FEX with uplink single mode and multimode fibre and works as expected.

I think you can not
each one have specific fiber requirement and different physical Layer characteristics 
this make both run same L2 layer for Port channel hard. 
so I dont think so
