Preliminary
Enhanced Digital Diagnostic Interface
The memory map in the following describes an extension to the memory map defined in SFP+ MSA. The enhanced
interface uses the two wire serial bus address 1010001x (A2h) to provide diagnostic information about the module’s
present operating conditions.
