摘要

我们实验证明了单波长56-GBd PAM4在1550 nm的传输，在光域中没有色散补偿，重点是短距离数据中心内的应用。采用低复杂度数字均衡器和最大似然序列估计，我们获得了33%的扩展范围，在考虑7%的fec开销的情况下，实现了长达4公里的无差错运行。

Extended-reach transmission of single-wavelength 112-Gbps PAM4 channel enabled by MLSE for intra data center applications

We experimentally demonstrate single-wavelength 56-GBd PAM4 transmission at 1550 nm, without chromatic dispersion compensation in the optical domain, focusing on short-reach intra data center applications. We obtained an extended-reach of 33% employing low-complexity digital equalizers and maximum likelihood sequence estimation, achieving error-free operation up to 4 km, considering 7% FEC-overhead.
