PURPOSE:To offset waveform distortion formed at the preceding passing by the suceeding passing and to remove inconvenience due to the accumulation of a waveform distortion by generating a reference signal having a prescribed level and inverting the phases of a synchronizing signal and a data signal in each passing of a node on the basis of the reference signal. CONSTITUTION:Data processing circuits constituting a synchronizing transmission system for transmitting/receiving a data signal on the basis of a synchronizing signal are provided with nodes A, B to transmit the data signal synchronously from the node A to the node B. A synchronizing signal generator 1 is formed in the node A and respective data processing circuits 2A, 2B process the transmission and reception of data on the basis of a synchronizing signal generated from the generator 1. An optical signal is transmitted between optical transmission modules 3A, 4B, 5B, 6B, 7A and optical reception modules 3B, 4A, 5B, 6A, 7A of respective nodes A, B and the phases of the synchronizing signal and data signal are inverted in every passing of one node by using inverters 9A, 9B. Thus, the waveform distortion formed at the preceding passing is offset at the succeeding to prevent the accumulation of waveform distortion. |
