Photovoltaic conversion Circuit is the basis of IEEE1394b optic fiber data bus system. Its states have an impact on the reliability of the system. This paper provides the implementation of self diagnostic function of photovoltaic conversion Circuit based on IEEE1394b, with the use of SFP（Small Form Factor Pluggable） optical transceiver and microcontroller. The optic fiber data bus system is established and some tests are carried out. From the network topology diagram and the temperature test result, it can be concluded that self diagnostic function meets the needs of practical applications and can effectively improve reliability and maintainability of the data bus system.
