10G CWDM SFP+/XFP Transceiver Modules with Built-in Digital Diagnostic Functions
10G CWDM SFP+/XFP transceiver modules are small form factor pluggable module for serial optical data communications. It is designed for single mode fiber and operates at a nominal wavelength of CWDM wavelength. There are 18 center wavelengths available from 1270 nm to 1610 nm, with each step 20 nm. A guaranteed minimum optical link budget of 14 dB is offered. Sopto supplies OEM service and Third-Party(Cisco, Juniper, HP, Dell etc.) compatible fiber optic transceivers.

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”. The DDM parameters have been internally calibrated.
