The design principle of the GPON optical transmission link is given and analyzed. The powerful simulation function of the OptiSystem software is described. The simulation model of the GPON optical transmission link based on the OptiSystem is presented according to the above principle. Based on this model the simulation results of the 2. 5Gbps transmission performance of both data and video optical links of the downstream service are also given and deeply analyzed. The corresponding conclusion is presented. Some problems which must be taken into account when optimizing the optical transmission link are pointed out.
