As burst optical packets have the feature of bursting and large dynamic scope

fast and accurate detection of their optical power is difficult.This paper briefly introduces the basic principle of optical power monitoring and describes the use of the use the fast sampling and holding technology method for its implementation.Furthermore

it uses this method to design a monitoring circuit and accomplishes the relevant calibration method.The experimental results show that with high accuracy and large dynamic scope this method meets the requirements for the burst optical power monitoring and greatly lower the speed requirement for A/D convertors.
