However, when the computer simulates the analog circuit signal, it uses various digital signal processing methods. There are certain differences between this digital signal processing method and the actual analog circuit design, and the actual analog circuit will be affected by the distribution parameters between devices. Therefore, the actual circuit parameters obtained according to the simulation are not accurate, and cannot guide the parameter design of the actual circuit very well, and have a great impact on the actual circuit parameter design; and the optical fiber simulation experiment system is not flexible enough because of the channel design. The parameters that can be changed are limited, and it is difficult to use them to study the applicability and optimal design of the system in different environments
