Abstract
Provided are an optical transceiver, an optical transmitter IC, and an optical receiver IC, which can be applied to both a case of coding an optical signal and a case of decoding an optical signal, and can suppress an influence of waveform degradation with an inexpensive circuit. The optical transceiver includes an optical transmitter, an optical receiver, and at least any one of: a first delay circuit included in the optical transmitter and configured to delay an input first multi-level digital signal by a delay time corresponding to an amplitude level of the first multi-level digital signal; and a second delay circuit included in the optical receiver and configured to delay an input second multi-level digital signal by a delay time corresponding to an amplitude level of the second multi-level digital signal.
