光二分路器规格的划定与设计研究

Demarcation and Design of Specifications of Two-output Optical Distributor

摘要:

通过数学建模，对构建光二分路器规格体系的相关技术参数及其关系做了分析与研究，给出了构建光二分路器规格体系和设计规格表、确定主要技术参数的原则和方法，设计制作了光节点信号电平最大允许改变量ΔP＝±0.2 dBm时的规格型光二分路器技术规格参数表，并通过实际应用证明了其合理性。实际网络设计中，要求光节点电平最大允许变化量｜ΔP｜一般都不会小于0.2 dBm，所以按照规格表设计制作的器件通常都能满足实际应用的需要。

Abstract:

The technical parameters of two-output optical distributor were analyzed with mathematical modeling. The principles and specification table for determining the key technical parameters are given. The technical specifications of two-output optical distributor with ΔP=±0.2dBm is designed and proved by practical applications. In practical designs, the maximum allowed variation is not less than 0.2dBm, so the devices designed according to the specification table generally can satisfy practical applications.
