- Abstract
A 100-Gbit/s PAM-4 (pulse amplitude modulation) transmission over 4-km standard single-mode fibre (SSMF) and a C-band 4 x 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 x 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.
