摘要
针对200Gbit/s净速率，实验比较了均匀PAM-4、6和8与概率整形PAM-8的帽形和杯形变体。在背靠背和20km测量中，帽形整形的80GBd PAM-8在接收机灵敏度上分别优于72GBd PAM-8和83GBd PAM-6最多3.50dB和0.8dB。

备注
Originally published in ECOC-2021. We have updated Figure 3. The change also affects the overall outcome. In contrast to the published version, compared to uniform PAM-8 72 GBd, PS-PAM-8 80 GBd performance is updated to 3.50 dB instead of 5.17 dB, while for PAM-6 83 GBd the gain becomes 0.8 dB instead of 2.17 dB. The changes are adapted in all sections except the experimental setup and DSP section
