When Cisco reports improper data out of the SFF-8472[1] MSA please open a support case showing the issue and how to reproduce so they can fix their drivers. It looks like they are reading/populating the connector type wrong that should be read from address 0xa0 byte 2 as seen in table 3.4 of the SFF-8472 MSA. Or the optic you have is presenting it incorrectly. RJ45 is 0x22 and LC is 0x07. I've found many bugs in the SFP/i2c driver in all versions of software (IOS, IOS-XE, IOS-XR) in our operation that cause improper data to be reported. - Jared yes, FTP transport is 'correct'...
