Transmission of 56-Gb/s PAM-4 over 26-km single mode fiber using maximum likelihood sequence estimation

We experimentally demonstrated a transmission of 56-Gb/s PAM-4 over a 26.4-km single mode fiber (SMF) at 1550nm using maximum likelihood sequence estimation (MLSE). We discuss the transmitter and receiver DSP that can improve PAM-4 performance.
