摘要

我们在IM/DD系统中实验展示了软fec限制下276 gbps的净速率128QAM-DMT传输，该系统具有单个c波段封装的EML, DAC和光电探测器，提出了一种栅格导频算法，用于信道均衡，只有1%的开销，达到每通道5.82比特/Hz的频谱效率。

Lattice pilot aided DMT transmission for optical interconnects achieving 5.820bits/HZ per lane

We experimentally demonstrate 276-Gbps net rate 128QAM-DMT transmission at soft-FEC limit in an IM/DD system with a single C-band packaged EML, a DAC and a photo-detector, proposing a lattice pilot algorithm for channel equalization with only 1% overhead reaching spectral efficiency of 5.82-bits/Hz per lane.
