Insertion Loss :指信号在线路中 insert 了一个 connector 后传输到下一级时的 loss,他们最好对信号不要产生影响,所以Insertion Loss应该越小越好。 Return Loss:signal 经过connector时会有一部分reflect回来,这个参数指的是return的loss。我们希望他反射回来的越小越好,也就是回来的损耗越大越好,所以Return Loss 也...

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。
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. ...

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.
An insertion loss estimator communicates with the cable tester and estimates insertion loss of the cable. A return loss estimator communicates with the cable tester and estimates return loss of the cable based on gain parameters of the physical layer device. 展开 ...
