<p>看来损耗不大,由于是室内连接,估计都不是光缆就是长的跳线!</p>

看来收发光功率都很正常,不知道LZ用来干什么生产用的,也不知道你们用的什么设备,对光功率的要求是什么范围,对一般传输设备来说的话就算质量很好了。收光和发光功率差别不大,同楼上所说,可能是室内用尾纤跳纤接的

&nbsp;&nbsp; 用来连接两个存储,对光纤质量要求很高。我不知道工业标准中SAN存储系统对光纤的要求是什么? 请各位提供,谢谢!

&nbsp;&nbsp; 不知道楼主说的是多少速率的设备~~``STM-1的好象-8____-15才算正常哟!!楼上的光功率数据是不是大了点??

<p>楼主好像单位用错了,应为dbm。&nbsp;&nbsp; dbm表示绝对功率电平,db表示相对功率电平。</p><p>列:一段光纤中继段,A点测试电平-6.5dbm,B点测试电平-10.5dbm,则A-B点衰耗为4db。</p>
