Optical code division multiple access has the advantages of safety and high efficiency, becoming the key technology in the optical fiber communication system. In the optical code division multiple access process, multiple users will inevitably have some interference between the users and affect the data transmission quality of the optical fiber communication system because multiple users send data at the same time. In order to improve the performance of optical fiber communication system, a new type of optical communication system based on optical code division multiple access is proposed. The performance of optical fiber communication system is analyzed through simulation experiments. The result shows that the technique of this paper can effectively suppress the interference between users and reduce the bit error rate of the optical fiber communication system. The technique is simple and the system transmission performance is improved.
