Notes:
1. Circuit ground is internally isolated from chassis ground.
2. Laser output disabled on TDlS >2.0V or open, enabled on TDiS <0.8V.
3.Should be pulled up with 4.7k - 10k ohms on host board to a voltage between 2.0V and 3.6V.
   MOD DEF(0) pulls line low to indicate module is plugged in.
4. Rate select is not used.
5. LOS is open collector output. Should be pulled up with 4.7k - 10k ohms on host board to a votagebetween 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.

SFP Module EEPROM Infomation and Management
The SFP modules implement the 2-wire serial communication protocol as defined in the SFP -8472. Theserial lD information of the SFP modules and Digital Diagnostic Monitor parameters can be accessed throughthe i'C interface at address A0h and A2h. The memory is mapped in Table 1. Detailed lD information (A0h) islisted in Table 2. And the DDlM specification at address A2h. For more details of the memory map and bytedefinitions, please refer to the SFF-8472, "Digital Diagnostic Monitoring Interface for Optical Transceivers"The DDM parameters have been internally calibrated
