PROBLEM TO BE SOLVED: To provide a transmitter simply achieving polarization bit interleaving.SOLUTION: The optical transmitter according to present invention for generating polarization-bit-interleaved signal includes: a branching unit for dividing an RZ modulated optical signal into two; a first phase change unit and a second phase change unit that are coupled with the branching unit, operate according to a prescribed modulator driving signal and apply a prescribed phase difference between the branched optical signals; a dual output modulator that includes a merging/branching unit for merging an optical signal output from the first phase change unit with an optical signal output from the second phase change unit and alternately dividing them into two outputs for every one pulse signal; and a polarizing multiplexer for multiplexing two optical signal strings output from the dual output modulator. |
