This paper introduce an automatic temperature compensation system based on the PIC for high speed small form pluggable(SFP) optical transceiver module. Comparing with conventional design, the module includes a microcomputer PIC,it can monitor a series of parameters of optical transceiver in real time by programming. Through this system,the SFP optical transceiver module can complete driver chip’s reading and writing rapidly. To ensure that the module can work in the best condition under the different temperature. The experimental results show that all parameters of SFP are regular as the change of temperature.
