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。
