Counterfeit assumes a Cisco label.
Third-party SFP modules are not counterfeit just unsupported.

It is entirely possible that the SFP isn't
even programmed for Cisco equipment.
For example a Dlink SFP will not work in Cisco equipment.

The bad CRC would tend to indicate the programming is
not correct for Cisco equipment.
This does not rule out counterfeit or bad hardware.
