Abstract
DD-LMS and CMMA equalizer are compared in 60GBaud PDM-PAM4 heterodyne detection PON. With lower computational complexity, DD-LMS scheme gets similar performance compared with CMMA scheme. The power budgets after 40-km SSMF transmission of DD-LMS and CMMA are 35-dB and 35.5-dB, respectively.
