Abstract: When a data signal of a first channel is an RZ signal having a pulse period T1 and a logic “1” pulse width m, a data signal of a second channel is an RZ signal having a pulse period T2 and a logic “1” pulse width n and the relation n<m is satisfied, a multiplexed signal D obtained by time-division multiplexing the data signals of two channels is input. A pulse signal with a pulse width k satisfying n<k<min(m, T2) is generated at timing of a leading edge of the data signal of each channel. When the multiplexed signal D is judged as logic “1” at timing of a trailing edge of the pulse signal, the data signal of the first channel is output. Similarly, when the multiplexed signal D is judged as logic “0”, the data signal of the second channel is output.
