针对目前常见光二分路器规格构成体系存在的问题,设计构建了两种不同规格参数的新型光二分路器规格构成体系与规格表。详细介绍了两种规格体系与规格表的设计思路、构建原理、规格参数值间的关系、确定规格参数值的方法和依据。通过实例介绍了两种规格体系和规格表的应用方法,对两种规格体系与规格表的异同点进行了分析和对比。应用表明,在一定条件下,无论采用哪种规格体系和规格表,均能选择到满足实际应用要求的、合适规格型号的光二分路器。但在选择规格型号时,使用以两路光纤长度差值为规格参数的规格体系与规格表,比使用以分光比为参数的规格体系和规格表,其方法要简单容易得多。
Aiming at the existing problems of the common optical splitter specifications, two specifications of the optical splitter specifications and specifications are designed and constructed. The design method, construction principle, the relationship between the specification parameters and the method and basis for determining the specification parameters are introduced in detail. The application methods of two kinds of specification system and specification sheet are introduced through examples. The similarities and differences between the two kinds of specification system and specification sheet are analyzed and compared. Application shows that under certain conditions, no matter what kind of specification system and specification table, can choose to meet the practical application requirements, the appropriate specifications and models of optical splitter. However, when selecting a standard model, it is easier and easier to use the system of specifications and specifications based on the difference between the lengths of the two optical fibers than the specifications and specifications of the spectrophotometer.
