摘　　要：对光二分路器的规格化及其设计作了分析与研究,剖析了过去以分光比等量递变来划定规格的方法所存的在问题,对之进行了修正和改进。提出了以两路光纤长度的差值等量递变来设计和划定规格的思路,并给出了具体的规格设计与应用表。理论和实践证明,这种规格表不仅使用非常简单和方便,更重要的是能够最大限度地满足系统载噪比与非线性失真质量指标的要求。The normalization and specifications design of the two-output optical distributor were analyzed and studied in this paper.It was dissected to set and divide specifications according to optical division ratio of equal variable,and the inherent shortcomings were pointed out,and the shortcomings were improved.The concept of setting and dividing specifications according to two optical fiber length difference of equal variable is brought forth,and the detailed specifications table was provided.To use the specification table is proved not only simple and convenient,but also the quality index of C/N and nonlinear distortion are proved by theory and practice.
