Based on analyzing the structure feature of WDM networks, this paper chooses some representative directed double-loop networks to study. It also provides the solutions of some congruence equations to compute the parameter values of L-shaped tile. According to the structure of L-shaped tile, it provides a formula to compute its network load. The experiment results demonstrate that there may be many load-balanced networks. For anyone of infinite families for G(N;r,s) , the distribution of loads is axis symmetric figure, and there is a upper bound and a lower bound for loads. The network is called optimal load network when its load equals the lower bound. These results are important to design optimal double net-works and improve transmission efficiency about networks.
