Serial Interface for ID and DDM
The SFP modules implement the 2-wire serial communication protocol
as defined in the SFP MSA.
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(A2h) is described in Table 3. For more details of the
memory mOL and byte definitions, please refer to the SFF-8472 (Rev
9.3, Aug. 2002), “Digital Diagnostic Monitoring Interface for
Optical Transceivers”. The DDM parameters have been internally
calibrated.
