Abstract: This paper introduces the composition and application characteristics of the digital optical fiber repeater system, compares the application differences between the digital optical fiber repeaters and the distributed base stations, and emphasizes the problems arising from the application of such repeaters in railways. Based on the characteristics and coverage modes of such repeaters, a solution is proposed to reduce the influence of time delay on railway communication by adjusting the setting parameters of the repeaters in a specific scenario. This paper provides a theoretical basis for setting the parameters of these repeaters in high-speed scenarios and for the security of the application of GSM-R system.
Key words: high-speed railway, digital optical fiber repeater, transmission delay, Field Programmable Gates Array(FPGA)
