Abstract For enlarging the capacities of WDM star networks free from the number of limited wavelengths, a scheme of reusing wavelengths twice is proposed in this paper. According to the scheme, not only the number of nodes can be increased twice, but also all the data wavelengths can be reused twice in the network and the throughput of the network is increased twice. Under the same number of nodes, not only half of fibers can be saved, but also the delay of network can be greatly lowered and the properties of the network can be efficiently improved.
