<b>:</b><div class="postmsg"><br /> 以前做过一些多模光纤方面的东西，附件是搜集到的一些资料。在低速情况下，传输距离主要是由光纤的衰减系数影响的，而高速情况下，光纤的色散则成为主要的因素。当然，传输距离和其他的因素也有很大的关系，例如入调制方式，入射方式等等。据已经报道的研究结果，1GB的信号在通常情况下可以传输500-1000米左右。<br /> 一些浅见。</div> <div class="postmsg">在这里有个问题想和大家讨论下，说错的地方请多多指出：<br /> 现在要确定一个方案：就是如何用850nm波长在 多模光纤中传输2Km或是5Km。（传输速率为10M--155M 或是10M--1G），那接收那边对应着用什么样的pin，该根据什么来选择？<br /> 额外的问题：要是用850nm的波长传输1G的带宽。它能传输多远的距离呢。（请教高手）<br /> 它应该选择什么样的激光器，什么样的驱动。好象AD公司这方面的芯片并不多，MAX的是挺多，但是不能支持多速率，多数是千兆的驱动器。我在多模里面，带宽和距离这方面的知识很有限，麻烦多多 指点。。还有。我是搞通信，我能帮上大家什么忙，也可以说一声。<br /> 我的初步想法是：用VCSEL，MAX3740。接收的暂时还没有想好。。请各位高手指点一下。。多谢拉。。。</div> <div class="postmsg">你说的是对的。。但是具体的方案。还是要更详细的讨论</div> <div class="postmsg">比如。我用vcsel来驱动850的。但是改用什么样的激光器的。要在多模里面传输2km，速率是10M到155M，要是1G以上的驱动是很多。但是低速率的芯片就很少。</div> <div class="postmsg"><<img src="static/image/smiley/default/titter.gif" smilieid="9" border="0"
