We propose a modification of the perfect shuffle connectivity graph used in optical networks, which ensures the balance of the traffic load on the WDM channels. When applied to the simple but popular case of 8 nodes, connected through a shortest path routing algorithm, it allows to increase the aggregate capacity of more than 14%.
