Filed: 2002-05-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and a device for optical transmission for evading XPM (cross phase modulation) between signals in a WDM (wavelength division multiplexing) transmission system which divides a signal inputted on the transmission side into n pieces and transmits the signals by lowering transmission rate of the signals to be transmitted in a WDM section to 1/n.   <P>SOLUTION: When the signals formed by dividing time-division synchronous multiplexing signal such as SONET/SDH (synchronous optical network/ synchronous digital hierarchy) into n pieces are transmitted by wavelength multiplexing the signals as they are, generation of (XPM: Cross Phase Modulation) as one of optical nonlinear effects is concentrated, reception characteristics are degraded and transmission distance is restricted. Thus, in the WDM transmission system that divides a client signal inputted on the transmission side into n pieces (n: an integer) and transmits the signal by lowering the transmission rate of the signals to be transmitted in the WDM section to 1/n, generation of the XPM is suppressed by transmitting the signals by providing phase difference among the respective signals to be transmitted in the WDM section by inserting exclusive and intrinsic delay into each of the signals divided into n pieces.  <P>COPYRIGHT: (C)2004,JPO
