摘要： Techniques for partitioning and/or combining at least a portion of an optical network tree including one or more array waveguide gratings (“AWGs”) and fibers in wavelength division multiplexing (“WDM”) passive optical networks (“PON”) with cascaded AWGs are disclosed. Example methods include deriving the optimal positions for the AWGs to minimize fiber cost and then determining the arrangement of cascaded AWGs to minimize the total cost of AWGs and fibers. Determining the arrangement of cascaded AWGs may include recursive partitioning followed by recursive combination. An example recursive partition-combination based algorithm for optimizing a tradeoff between the AWG cost and the fiber cost is disclosed.

摘要翻译： 用于分级和/或组合包括一个或多个阵列波导光栅（“AWG”）的光网络树的至少一部分和具有级联AWG的波分复用（“WDM”）无源光网络（“PON”）中的光纤的技术 被披露。 示例方法包括导出AWG的最佳位置以最小化光纤成本，然后确定级联AWG的布置，以最小化AWG和光纤的总成本。 确定级联AWG的布置可以包括递归分区，随后是递归组合。 公开了一种用于优化AWG成本和光纤成本之间权衡的递归分区组合算法的示例。
