迪庆藏族自治州爱全回答： 回波损耗(RETURN LOSS) 回波损耗是电缆链路由于阻抗不匹配所产生的反射,是一对线自身的反射.不匹配主要发生在连接器的地方,但也可能发生于电缆中特性阻抗发生变化的地方,所以施工的质量是减少回波损耗的关键.回波损耗将引入信号的波动,返回的信号将被双工的千兆网误认为是收到的信号而产生混乱.
敞念17786571862问： 传输线驻波状态时的驻波比和反射系数是多少? - ？
迪庆藏族自治州爱全回答： 传输线驻波状2113态时的驻波比和反射系数是1,0. 反射系数、驻波比、S参数之间的关系回波损耗(Return Loss): 入射5261功率/反射功率, 为dB数值 反射系数(Г): 反射电压4102/入射电压, 为标量 电压驻波比(Voltage Standing Wave Ration): 波腹电压/波节电压 S参数: S12为反向传输系数,也就是隔离.S21为正向1653传输系数,也就是增益.S11为输入反射系数,也就是输入回波损内耗,S22为输出反容射系数,也就是输出回波损耗. 四者的关系: VSWR=(1+Г)/(1-Г) (1) S11=20lg(Г) (2) RL=-S11 (3)
敞念17786571862问： 回波损耗的基本介绍 - ？
迪庆藏族自治州爱全回答： 回波损耗:在高频场合,反映行波在保护设备的过渡点处被反射的比例. 在这一参数下可直接衡量, 保护器件与系统的涌波阻抗的匹配程度.回波损耗:return loss.回波损耗是表示信号反射性能的参数.回波损耗说明入射功率的一部分被反射回...

敞念17786571862问： input return loss是什么意思 - ？
迪庆藏族自治州爱全回答： 输入回波损耗
敞念17786571862问： 哪位知道VSWR和RETURN LOSS之间的转换关系 - ？
迪庆藏族自治州爱全回答： 驻波比小于3,就是要求你的反射系数要小于1/2,也就是说你的功率损耗不能超过入射功率的25%,也就是说你的return loss要大于6db,return loss越大,你的信号反射的越少的,当然效率越高啦!好像工业上要求一般驻波比小于2的.
敞念17786571862问： 光纤测试标准 - ？

敞念17786571862问： 光纤活动连接器的性能 - ？
迪庆藏族自治州爱全回答： 光纤连接器的性能,首先是光学性能,此外还要考虑光纤连接器的互换性、重复性、抗拉强度、温度和插拔次数等.由于光纤连接器也是一种损耗性产品,所以还要求其价格低廉.在一定程度上,光纤连接器的性能影响了整个光传输系统的可靠...
敞念17786571862问： Java中,return的具体用法! - ？

敞念17786571862问： return 0,return - 1,return - 2 return分别是什么意思,怎么用? - ？
迪庆藏族自治州爱全回答： return语句代表函数的调用结束,如果return 0就是调用结束并返回数字0,return就是调用结束无返回值.如在JavaScript中: //情景1 function a(){return 0; } var result=a(); //result=0//情景2 function a(){return; } var result=a(); //result=undefined,undefined代表未定义,而不是返回0或者null
