摘　　要：针对高速小型可插拔式SFP(small form pluggable)光发射模块输出光功率随外部温度变化而改变的缺点,基于PIC单片机设计实现了一种自动温度补偿系统。通过改变光发射模块内部的硬件电路设计,将小型封装的PIC单片机嵌入到光发射模块当中,由编程控制实现对SFP光发射模块一系列工作参数的实时监测,同时根据监测到的温度参数的变化,利用查找表法对光发射模块的激光偏置电流进行实时补偿,确保外界温度条件发生改变时光发射模块输出光功率的稳定。实验结果表明当外界温度发生改变时,光发射模块的输出光功率、总抖动、消光比等性能参数都符合设计要求。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 w riting 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 .
