Performance Analysis of Reed-Solomon Code in 25G-EPON System

Abstract

Abstract: Forward error correction is the key technology to ensure the reliability of data transmission in 25G-EPON system. For 25G-EPON system, random errors and continuous burst errors often occur in the process of data transmission due to the high transmission. By analyzing the RS coding and decoding algorithm and selecting the appropriate RS characteristic parameters, the influence of these parameters on the transmission performance of 25G-EPON system is simulated and analyzed. Thenthe appropriate RS code scheme is chosen for 25G-EPON communication systems. The experimental results show that under the premise of satisfying the reliability of the 25G-EPON system, the coding efficiency should be reduced as much as possible, the redundancy of coding should be improved and the coding scheme with shorter code length should be adopted, so as to improve the coding gain of the RS code and reduce the bit error rate of information transmission. It is shown that RS (1023,847) code can correct up to 880 consecutive bit errors, and the coding gain can reach 8.834 dB when the symbol error rate reaches 10-12, which can meet the transmission requirements of 25G-EPON system. Therefore, RS(1023,847) code is selected as the forward error correction code of 25G-EPON system.
