Experimental Demonstration of 100-Gbps Optical PAM-4 Transmission Over 4-Km SSMF Using Wiener Filter

We experimentally demonstrate a 100-Gbps optically-uncompensated PAM-4 transmission over 4-km SSMF at 1.55-um by using Wiener filter. The performance of the adaptive filters, including LMS and Wiener filter, are both analysed and compared.
