Cisco branded Finisar transceivers ?

I've found some weird transceivers which are CISCO Branded but when checking the firmware they are Finisar.

When checking the transceiver via a Nexus switch they report part number:

FTL410QE2C-C1

Which is a Finisar model, but they are branded as CISCO QSFP-40G-SR4 (Which usually we expect AFBR-79EIPZ-CS2 or similar)

When checking the CISCO label, the only difference is that the serial numbers use different prefixes and the construction is slightly different.

Has anybody seen something like this or knows what they are?

To me they seem like Finisar transceivers sold by CISCO, but I don't really know.

They also don't report TX and RX power, they just report N/A.

Could they be different manufacturer transceivers or just counterfeit ones? (Even if for a counterfeit maybe would make much sense to use high quality after market transceivers like finisar)

Thanks!
