瞄准系统中的转换器、瞄准控制器及传输电缆部分是最容易受干扰的环节，也是瞄准系统可靠性的控制点。
The conversion part, controller and connection cable are easy to be jammed and are the reliability control point in the aiming system.
第二部分是光纤传输和光电转换器，从传感头输出的频率调制信号驱动装在高压端的发光二极管，进而转换成光脉冲信号；
The first one is a sensor head converting the current flowing in the power line into the optical pulse FM signal. The second one is optical fiber transmission and optolectric conversion.
由于波长转换器的成本较高，且使用过多的波长转换器会增加传输时延，在进行波长路由分配时应尽可能减少波长转换的次数。
It is expensive to use wavelength convertor, which causes a long delay. So it is better to minimize the number of wavelengths conversion.
由于线路传输距离较长，工厂和办公室之间增加了光电转换器，以增加传输距离。
As the long distance lines, factories and offices, increased between the Media Converter to increase the transmission distance.
由于线路传输距离较长，工厂和办公室之间增加了光电转换器，以增加传输距离。
As the long distance lines, factories and offices, increased between the Media Converter to increase the transmission distance.
