ABSTRACT:
The present invention provides an optical transceiver to reduce a crosstalk in sufficient. The optical receiving unit of the invention includes an O/E-converter, a signal processing unit, and an offset voltage setting unit. The input of the signal processing unit, connected to the output of the O/E-converter, receives an electrical signal from the O/E-converter. The offset voltage VOFFof the signal processing unit is kept constant, independent of the phase difference between signal in the optical transmitting unit and in the optical receiving unit, by the offset voltage setting unit.
