SFPTotal Team research issues about compatibility between fiber optical transceivers and network switching equipment. Our engineers develop tools, devices and software for programming fiber-optic transceievers including ethernet transceivers, passive and active optical cables of popular form-factors GBIC, SFP, SFP+, SFP28, XFP, QSFP, QSFP+, QSFP28. Programming boards are designed to solve the main problems that arise in the practice of Internet service providers, suppliers of network equipment and system integrators on the process of working with optical transceivers and switching equipment, and requiring reprogramming of transceivers.

SFPTotal devices support a special protocol that allows access to all address spaces of transceivers and implements instructions for programming write-protected transceivers.

Programming boards

  1. SFPTotal PG
  2. SFPTotal Mini
  3. SFPTotal Plus
  4. SFPTotal Whistle


SFPTotal programmers can be used to solve the following tasks:

  • Programming transceiver's EEPROM/Flash through I2C databus
  • Ensuring compatibility between network equipment of different manufacturers
  • Programming write-protected transceivers using passwords or scripts
  • Programming write-protected transceivers using brute-force mode
  • Changing PHY controller settings
  • Rebranding OEM transceivers
  • Reading DDM (Digital Diagnostics Monitoring) information
