USB接口由于技术发展时间长，技术成熟得到广泛应用。但传输速率高、频率高，导致它传输距离受限，通常最远传输5米，每加一级USB-HUB，可以延长5米，最多能加5级USB-HUB，表1是USB传输速度和距离对照表。

表1：USB传输速度和距离对照表

USB视频采集卡，就是数据卡将DV摄像机、录像机、播放机中的视频内容采集到电脑中进行制作、剪切，图1为USB视频采集卡的系统框图。视频采集卡与主机电脑通过USB传输，这个距离通常有几十米到一百多米的距离。根据上面表中的传输距离来看，是很难实现的，就算通过5级USB-HUB，也难满足要求，并且USB会产生数据信号的衰减。

图1：USB视频采集卡的系统框图

面对上述的问题，我们对各种传输进行了调研，例如USB-HUB，USB-RJ45，USB-Fiber等方案进行了比较，分别对传输距离、成本进行了比对，表2为各种传输方案的比较表。

表2：各种传输方案的比较表

USB-RJ45理论上可以传输100米，但实际上传输50米以内效果更好。而从表2可知，USB-Fiber方案是目前效果最好的。对于USB-Fiber方案，里面主要包括光模块、传输光纤等成本。根据目前项目100-200米的需求，选择了FIRECOMMS的EDL301T以太网光纤收发器作为传输模块。此模块成本低、体积小，采用650nm光纤，相对来说光纤的价格也低，各方面综合考虑，此方案是最优选择。

在实际的电路设计中，需将USB2.0信号通过专用芯片转换成lvpecl信号，用于驱动光模块。因此对光模块的设计应为通用设计，在USB两端增加EDL301T模块，中间通过光纤传输，这样就可以远距离传输了。EDL301T的体积只有通常的光器件的1/6大小，PCB板设计可以做到很小。值得一提的是，该方案功耗很低，通常模块3.3V供电，需要100mA的功耗，此模块只需要30mA多的功耗，而其速率可以达到100Mbps，符合USB2.0的传输要求，图2为EDL301T的电路图。

图2： EDL301T的电路图

对于100Mbps以太网来说TX和RX差分线通常串0.1uF电容，对于1Gbps，通常差分线串0.01uF的电容。由于上述电路为LVPECL电平，LVPECL的输入是一个具有高输入阻抗的差分对，该差分对共模电压需要偏置到VCC-1.3V，这样允许的输入电平动态最大。对于LVPECL电平，我们通常用调整上下拉电阻来优化功耗，表3为LVPCL逻辑电平表。

表3：LVPCL逻辑电平表

通过上述设计，能够让USB传输100-120米，由于光纤传输损耗很小，信号传输非常稳定可靠。

在设计USB远距离传输的PCB板子时，建议采用4层板，这样对于100M传输更加稳定可靠。在滤波时，TX/RX电源最好单端滤波供电，这样对于EDL301T更加稳定，对于远距离传输也更加可靠。

USB接口更远距离传输设计，最上面的传输距离怎么来的..？
- 猪哥哥回复：这是根据数字信号传输速率以及线缆传输时受干扰等导致误码率确定的，如果你将传输速率降低，线缆阻抗好，那么你就能传很远，如果你传输速率很高，线缆阻抗质量低，那么传远了后你看眼图就是不清晰的，你的误码就会非常高，导致不能正常传输。
