摘　　要：分析了光二分路器常规体系存在的问题,给出了解决的办法与思路,推出了一种新的光二分路器规格体系,详细介绍了这种规格体系的构建方法和设计过程。这种新的光二分路器规格体系,相邻规格型号的适用范围之间既没有重叠也没有断带情况,在每一种规格型号不同的适用范围内,都能保证光节点电平的变化量始终在相同的允许范围内。而且在选择规格型号时,不用计算网络所需分光比,而是直接根据两路光纤长度的差值,由规格表选择合适的规格型号,所以使用起来非常简单方便。This paper analyzes the defects of the conventional systems of two-output optical distributors and gives the ideas and solutions. Specifically, it presents a new specification system and elaborates on its establishing method and design process. In this system, the application scopes between adjacent specifications are neither overlapped nor broken and the variations of the optical node levels of every specification always remain within the same allowable scope in different application scopes. The specifications are not chosen by calculating the splitting ratio that the network needs, but by the specification table directly ac-cording to the two-output fiber length differences. Therefore, it is very simple and convenient for the designers to use this sys-tem.
