Optimal Design of High-speed 650nm Optical Fiber Communication System

The optimal design of high-speed 650nm plastic optical fiber (POF) communication system with independent design silicon-based 650nm optical transceiver chips is implemented in this paper. Firstly, the parameters of optical path are obtained in theory by analyzing and calculating of system optical path based on the hemispherical and spherical lens system model. Then, the system optical path is designed and simulated in the software TracePro with the help of the control variables method. Finally, the system experiments of optical power, transient response and transmission characteristic are completed. The test results indicate that the output optical power is increased by 30μW using the lens and polished POF. The system has good transient. And the bandwidth of 180MHz is obtained to satisfy the demand of 100Mbps POF communication system.
