The use of multilevel signaling has applications in increasing the information bandwidth over optical fiber link, thus obviating the necessity to replace cable whose capacity is fully utilized at a given bit rate. The communication end-to-end delay can be minimized and the reduction in signal to noise ratio (SNR) caused by multilevel signaling is not significant over short distances of optical fiber. The use of multilevel signaling for light Intensity Modulation Direct-Detection (IM-DD) systems has received an attention in the literature [12–15].
