The application and realization of the digital diagnostic monitoring function for SFP optical transceiver module

SFP optical modules are widely used in the practical network, this paper proposes an application and realization of a monitoring system for SFP optical transceiver module. It analyses the basic principles of digital diagnosis monitoring function of the intelligent SFP optical modules first. Then it introduces the SFF-8472 protocol architecture and the basic principles of I2C bus. With the adoption of this system, the key parameters of optical transceiver module's monitoring can be realized. Moreover the testing results of the optical transceiver module base on this system are according to the requirements.
