在设计与构建星形光纤网络时，常规的方法是根据各条光纤线路的不同损耗，设计出不同分光比的光分路器，对光功率进行不均等分配，最终达到各光节点功率相等。但每个光分路器都是特制的，没有通用性，不利于设计、生产、备用和维修。文章根据目前光接收机输入功率动态范围都比较宽，允许光功率在一定范围内变化的特点，提出用光均分器合理构建和设计星形光纤网，并通过实例介绍了多元光均分网络的构建与设计方法和步骤。

In designing and constructing star fiber-optic networks, optical splitter with different splitting ratios are designed conventionally according to the different losses of each optical line to distribute optical power unequally so that equal power reaches all optical nodes. However, every optical distributor is specially designed, not to be used universally, which is disadvantageous for design, production, backup and maintenance. Since the present optical receivers have fairly wide dynamic range of input power, allowing it to vary within a certain range, this paper proposes that optical star networks are rationally designed and constructed with optical equal distributor and introduces by examples the design and construction of multiple optical equal distribution networks.
