| 摘 要： | 误码率是数据传输设备的衡量指标之一,误码率测试是SFP光通信模块生产与设计中重要的环节。针对SFP光通信模块设计了一种基于FPGA的误码率测试系统,系统采用并行m型伪随机序列编码,可实现PRBS-7至PRBS-31标准的m序列码流生成,与SFP光通信模块的通信速率为1.25Gbps。系统打破常规测试的局限性,模块连接简便,可以在短时间内对SFP光通信模块进行准确测试,提高了SFP光通信模块误码率测试的效率。

| Abstract: | Bit-error rate（BER） is a criterion used for testing the data transmission equipment and BER test is an important procedure in manufacturing and design of SFP optical communication modules. In this paper, a BER test system based on FPGA for SFP optical communication module is proposed. This system employs parallel m-sequence based pseudo-random coding and therefore is capable to generate standardized m-sequences from PRBS-7 to PRBS-31. The communication rate between BER test system and SFP optical communication module is 1.25 Gbps. The proposed BER test system employed a novel testing method and connection to SFP modules is simple, thus it is able to test SFP modules in a short time with high accuracy, i.e., the test efficiency is improved. |
