How to further improve the performance of optical communication systems will be an important guarantee for the successful construction of next-generation optical networks. This paper builds an optical transmission simulation system on the VPI simulation platform. By changing the system parameters such as fiber length, transmitter bit rate, global bit rate and sampling rate, observed and analyzed the changes of spectrum and eye diagram of the optical transmission simulation system. The experimental results show that the transmitter bit rate and global bit rate have a greater impact on the spectral bandwidth of optical communication systems than the optical fiber length and sampling rate.
