Demonstration of 260-Gb/s Single-Lane EML-Based PS-PAM-8 IM/DD for Datacenter Interconnects

We experimentally demonstrated single-lane EML-based IM/DD 106-Gbaud PAM-4 and PS-PAM-8 signals transmission over 1-km NZDSF based on Pre-EQ and clipping technique. 260-Gb/s PS-PAM-8 signal transmission can be achieved.
