We analyze the performance of fractionally spaced maximum likelihood sequence estimation (MLSE) equalizers in OOK and PAM4 optical systems using optical and electrical components with cut-off frequencies less than the baud rate. It has been demonstrated that signals suffering from optical and electrical impairments can be efficiently equalized in cheap direct-detection optical receivers using MLSE equalizers with one or two samples, depending on the extent of bandwidth limitations.
