SFP Module EEPROM Information. and Management
The SFP+ modules implement the 2-wire serial communication protocol as defined in the SFP -8472.
The serial ID information of the SFP+ modules and Digital Diagnostic Monitor parameters can be accessed through the I2C interface at address A0h and A2h. The memory is mapped in Table 1. Detailed ID information(A0h) is listed in Table 2. And the DDM specification at address A2h. For more details of the memory map and byte definitions, please refer to the SFF-8472, Digital Diagnostic Monitoring Interface for Optical Transceivers.
