>protocol was that communicated this information down to the SFP

For EEPROM access in a SFP+ it's I2C with is well documented and used in tons of embedded stuff .. commercial logic analysis tools can handle this protocol, as can your average $10 Arudrino.

Of course writing certain parts of the SFP+ EEPROM are "protected" for obvious reasons but that certainly hasn't stopped people.
