摘要

在本文中，我们以 30GHz-EML 为基础，实验演示了在标准单模光纤上传输 112 Gb/s PAM-4 和 PAM-6 信号，传输距离分别为 2 千米和 10 千米。我们使用了三种算法，其中 MLSE 的误码率性能最佳。考虑到算法的复杂性，在 MLSE 之前级联了 FFE。对于 PAM-4 信号，与 FFE 相比，使用 MLSE 时灵敏度提高了 1 dB。

Demonstration of 112Gb/s PAM4/6 signal transmission in IM/DD systems using MLSE

In this paper, we experimentally demonstrated the transmission of 112 Gb/s PAM-4 and PAM-6 signals over standard single-mode fibers for 2 km and 10 km based on a 30GHz-EML. We have used three algorithms, of which MLSE has best BER performance. In consideration of algorithm complexity, FFE is cascaded before MLSE. For PAM-4 signal, the sensitivity is improved by 1 dB when using MLSE compared to FFE.
