答:光纤连接器引入的损耗有插入损耗( insertion loss)和回波损耗(return loss)。插入损耗是由光纤 端接缺陷造成的光信号损失,插入损耗越小越好。回波损耗是由于光波在光纤端接的界面处产生菲涅耳反 射,反射波对光源造成干扰,故回波损耗越大越好。 ITU建议回波损耗值不小于 38dB。
S11：端口2匹配时，端口1的反射系数；S22：端口1匹配时，端口2的反射系数；S12：端口1匹配时，端口2到端口1的反向传输系数；S21：端口2匹配时，端口1到端口2的正向传输系数；
回波损耗(Return Loss)是以对数形式(dB) 表示反射系数的一种方法。回波损耗是反射信号低于入射信号的dB ...
Insertion Loss (IL) is a measurement of the loss of light between two fixed points on an optical fiber. It can be understood as the loss of optical power caused by the intervention of optical devices in the optical fiber link of an optical communication system, and its unit is dB. Formu...

A comprehensive reference guide about the IL/RL of fiber connectors: What is insertion loss? What is return loss? Why are IL/RL so important? What will influence the numerical value of the IL/RL? How to reduce the loss? Find the answers in this article.
Connector Return Loss vs. Insertion Loss A connector is one of many transmission line elements in a signal path between a transmitter and receiver in amutli-board system. When discussing interconnects, most designers tend to focus on vias as an inductive impedance discontinuity. In other words, ...
