摘要
以星—树枝型光链路为例 ,采用控制末端载噪比和控制末端功率两种方法 ,分析推导出星—树枝型光链路光分路器分光比和光发射功率的通用公式 ,并结合实例比较两种计算方法的结果 。
This paper analyzes and derivates general formula of the optical sender power, optical divide ratio and optical receive power in star-tree branch optical link , with the star-tree branch optical link for the model using two of methods of controlling extremity carrier noise ratio and end power. It uses practical examples to compare the computing result of the two methods, and explains the feasibility of two design methods in practice.
