Technical Examples
Disclosed are an apparatus and a method for shortening a processing time at each node in an optical network. A transmission optical cross-connect (OXC) determines a transmission rate corresponding to the transmission speed of the signal to be transmitted. An optical receiver and an optical transmitter are stabilized by means of the transmission rate. In addition, a transmission OXC transmits the transmission rate to an OXC aligned between the transmission OXC and the receiving OXC, thereby stabilizing the OXC. Each of the OXCs detects the transmission speed of the optical signal to be received so that a time required for converting the transmission speed is reduced.
