With the rapid development of information technology, optical fiber communication system has been widely adopted as a technical solution for high-speed and large-capacity signal transmission. The performance of optical fiber communication system not only affects the speed and stability of information transmission, but also the reliability and efficiency of the entire communication network. Therefore, in-depth research on the performance and optimization strategy of optical fiber communication system is of great significance to the development of communication technology.1. Performance analysis of optical fiber communication systemThe main performance indicators of optical fiber communication system include communication capacity, transmission distance, bit error rate and signal transmission speed. Among them, communication capacity refers to the maximum amount of data that can be transmitted by the system under certain spectrum width and signal-to-noise ratio conditions. Transmission distance refers to the maximum distance that optical fiber can support during signal transmission. Bit error rate is a measure of the error rate caused by signal loss and interference during signal transmission. Signal transmission speed refers to the amount of data transmitted by optical fiber communication system per unit time.In optical fiber communication system, the main bottleneck of performance lies in signal transmission distance and transmission speed. Transmission distance is affected by optical fiber loss and dispersion effect. Optical fiber loss mainly comes from the attenuation and propagation of optical signal during transmission, while dispersion effect causes time broadening of optical signal during transmission. Both factors will cause changes in the intensity and shape of the optical signal, thereby affecting the transmission distance and speed.In order to improve the transmission distance and transmission speed of the optical fiber communication system, corresponding optimization strategies need to be adopted.2.

Common optical fiber materials include single-mode optical fiber and multi-mode optical fiber. Single-mode optical fiber is suitable for long-distance transmission and has low loss and dispersion characteristics. Multi-mode optical fiber is suitable for short-distance transmission and has a faster transmission speed.2. Optimization of optical signal modulation technologyOptical signal modulation technology refers to the process of converting electronic signals into optical signals. In optical fiber communication systems, the optimization of optical signal modulation technology can improve the transmission speed and stability of signals. Common optical signal modulation technologies include direct modulation, external modulation, and internal modulation.
