关于分光器真是一窍不通，没见过，规格,尺寸，工作原理，真的是不懂
恳请了解的兄弟，帮帮忙，谢谢了!

<p>请教楼上的，接头损耗指的是什么？</p><p>谢谢</p>

时间: 2007-9-12 11:24

作者: x7656607

<p>接头损耗很好理解啊光纤和光纤接口连在一起不是需要接头嘛</p><p></p>

作者: ss1976

谢谢楼上的回答，但是我的理解是光纤和光纤之间是通过连接器连接，是不是应该算做连接器损耗啊，请指教

时间: 2007-9-13 15:47

作者: x7656607

<p>呵呵应该是这样 每个光纤都有2根接头  这就有了0.2db的衰减</p><p>然后一侧光纤与另一根光纤通过连接器连接衰减就为4x0.1+1x0.4=0.8db 的损耗了</p><p>一般发端的光功率很高滴   有时候因为到终端这边功率高的还有误码哈哈</p><p>加个衰减器就好了    这东西不需要精确到小数点后面的吧</p><p></p><p>对了  连接器应该叫法兰盘哦</p>

<p>多谢 x7656607解惑，呵呵</p><p>我对这个接头损耗一直不太理解，不过在算总的损耗时一般是把它忽略掉的</p><p></p>

作者: zfzf

<p>5楼的"接头"应该理解为熔接点</p><p>"连接器"应该理解为法兰</p><p>对吧</p><p>由OLT到最远的ONU总的损耗应该在27DB以下</p>

<p>哇,都是专业的嘛</p><p>一般来说,1分多本来就是有衰减的</p><p>用于连接的法兰盘也是有衰减的</p><p>资料网上都有的吧~~~~</p><p>工作原来的话,下行的报文是广播下来的,是无源的</p><p>说实话,我不是搞硬件的,对于分光器的原理,还真说不上来哈</p><p></p>
