A novel single-hop WDM network, the AWG∥PSC network, comprises an AWG in parallel with a PSC. The AWG and PSC provide heterogeneous protection for each other; the AWG∥PSC network remains functional when either the AWG or the PSC fails. If both AWG and PSC are functional, the AWG∥PSC network uniquely combines the respective strengths of the two devices. The throughput of the AWG∥PSC network is significantly larger than the total throughput obtained by combining the throughput of a stand-alone AWG network with the throughput of a stand-alone PSC network. The AWG∥PSC network provides, over a wide operating range, a better throughput-delay performance than a network consisting of either two load sharing PSCs in parallel or two load sharing AWGs in parallel.
