LCP-8500A4EDR

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.
