摘　　要：提出了一种基于规格型光二分路器的多路光功率分配方法,将多路分光比的设计及其分路器的制作转化为用各种规格型号的光二分路器的组合实现多路光功率的合理分配。给出了一种新的光二分路器规格表,并通过具体实例详细介绍了这种多路光功率分配的方法和过程。事实证明,该方法具有简单、易行、网络成本造价低、利于网络器件的备用和维修的优点。A method of multi-path optical power distribution based on normalized two-output optical distributor is presented in this paper. It changes design of multi-path optical division ratio and making of optical distributor into combining multiple normalized two-output optical distributor for multi-path optical power distribution. A new specification table of two-output optical distributor is provided, and the method and procedure of muhi-path optical power distribution are introduced by examples in detail. This method is proved fight and simple, the network is low-cost, backup and maintainence are advantageous.
