大家看看这是什么东西？...

<br/>大家看看这这是什么东西？在综合布线当中干什么用的？

<p>我叫它光纤转换器。光纤进入TX口。RJ45口连出网线接入交换机，一般用在长距离的光纤链路与交换机的连接上。</p>

<p>楼主在大马路上捡得吧！</p>

<p>拜托2楼不懂不要乱讲!</p><p>这是75欧转120欧的转换器,统属讲就是双绞线转E1线.通讯上会用到!</p>

<p>是G.703平衡非平衡转换器.</p><p>楼主是同行。</p>

<p>呵呵 其实说是RJ45－BNC转换器更好理解些</p><p>RJ45：120 Ohm balance</p><p>BNC:75 Ohm&nbsp; unbalance</p><p></p>

<p>RJ45-BNC</p><p>很少用了</p>

<p>比较老了哇。</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p>

<p>疯了，我路过的，没看到</p>
