A 100‐Gbit/s PAM‐4 (pulse amplitude modulation) transmission over 4‐km standard single‐mode fibre (SSMF) and a C‐band 4 × 80‐Gbit/s PAM‐4 transmission over 8‐km standard SSMF experimentally demonstrated. A digital Wiener filter (WF) at the receiver side is utilised to compensate the impairments introduced by the transmission link. Bit error rate below 7% forward error correction threshold (3.8 × 10 −3 ) is achieved with received optical power of 0 dBm for the single lane 100‐Gbit/s transmission and around −4 dBm for the four channels after 8‐km transmission with WF, which is over one order of magnitude better than that without equalisation. The results indicate that WF is a good enough option for practical application in short reach optical interconnect.
