In order to improve the accuracy of data transmission in optical fiber networks, optical fiber network data transmission requires fast real-time identification of network channel border nodes. A fiber channel based on the channel spacing of the baud interval channel is proposed Real-time rapid identification of boundary nodes. Firstly, the optical fiber network channel model is constructed, the overall block diagram of the border node identification of optical fiber network data transmission channel is designed, the multipath characteristics are measured at the boundary nodes of the network channel, the intersymbol interference suppression is implemented by using the fractionally spaced sampling technique, The realization of the channel boundary node identification. Finally, the simulation analysis is carried out. The simulation results show that this method has higher real-time and accuracy in identifying fiber channel nodes, lower error rate and better fidelity of network data transmission.
