Claim:
1. An optical communication cross-connection device for exchanging an OTN signal through optical communications, comprising: a plurality of OTN signal processing units for asynchronously conducting OTN signal processing; and a space switch connected between the plurality of OTN signal processing units, for conducting bidirectional signal exchange for the OTN signal, wherein a first OTN signal processing unit and a second OTN signal processing unit that conduct signal transmission among the plurality of OTN signal processing units subject the OTN signal to skew processing on one side and deskew processing corresponding to the skew processing on another side between the first OTN signal processing unit and the second OTN signal processing unit or between a communicating end-side one of the first OTN signal processing unit and the second OTN signal processing unit and a communicating end-side OTN signal processing unit of an optical communication cross-connection device of a communication counterpart destination with respect to the optical communication cross-connection device, and share a clock for the signal transmission therebetween.
