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.
