This research investigated a dual-star parallel synchronous fiber laser network system. It theoretically proves the network parallel node cluster synchronization and the cross synchronization with dual-star, forming the theoretical mode of the network "star-node" synchronous cluster, and successfully predicting the parallel existences of "star-node" synchronization cluster and double "star-node" synchronous cluster. The synchronization of two groups of independent parallel nodes of the single-ring erbium-doped fiber laser and the corresponding laser ring as the network dual-star dual-ring erbium-doped fiber laser is simulated successfully. The single "star-node" synchronization cluster, chaotic synchronization cluster, quasi-period synchronization cluster, parallel double "star-node" synchronization cluster are found. The realization of a dual-star parallel synchronous fiber laser network under different parameters is analyzed. Compared with a single star network, the dynamic behavior of the network’s structure becomes rich, and its double send terminal breakthroughs the limitation of the single terminal send parallel network and shows the obvious advantages and can transfer information efficiently. This research has significant implications for optical networks, fiber laser synchronization networks, and applications.
