<P>PROBLEM TO BE SOLVED: To provide an optical transceiver in which a burden on an electric circuit for skew reduction is reduced by reducing skew by a physical method. <P>SOLUTION: The optical transceiver includes: an optical transmitting part 12 including a plurality of light sources for separately transmitting a plurality of signal lights with different wavelengths; an optical receiving part 13 including a plurality of photoelectric converters for separately receiving a plurality of signal lights with different wavelengths; and a multiplexing/demultiplexing circuit part 14 for multiplexing or demultiplexing a plurality of electric signals corresponding to the plurality of signal lights with different wavelengths. Delay time differences (skew) among the plurality of electric signals from one another are reduced by changing path lengths in each of respective paths of the plurality of electric signals at least at one path side between a plurality of paths 17 where the plurality of electric signals between the optical transmitting part 12 and the multiplexing/demultiplexing circuit part 14 each propagate and a plurality of paths 18 where the plurality of electric signals between the optical receiving part 13 and the multiplexing/demultiplexing circuit part 14 each propagate. <P>COPYRIGHT: (C)2011,JPO&INPIT |
