Abstract： With the continuous improvement of network needs and passive optical networks continue to lower the cost, national fiber optic network developing has been mushroomed in recent years, however, all of the optical network laying and routine maintenance are required for link loss testing. This paper proposed and implemented to measure the optical networks loss of multi-functional instrument design, it also introduces the main components of the selection and functions,the hardware structure of the various functions and related circuit theory are also included.You can find the algorithm for accurate calculation of optical power and the specific implementation.
