光二分路器两种新的规格体系及其应用与对比

Two New Standard Systems and Their Application and Comparation of Two-output Optical Distributor

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。

To solve the problems in common standard system of two-output optical distributor,two new standard systems and specification table are designed with different parameters.The design principles,relations between parameter values,and methods and reasons for determining parameter values are presented.The application methods are introduced by examples,and the similarities and differences are analyzed and compared.Applications show that the two standard systems and specification tables are able to meet the demand for selecting apposite two-output optical distributor under given conditions.But the standard system and specification table with optical fiber length difference is far simpler and easier in use than that with optical divide ratio.
