摘要： The printed circuit board with the respective components of the optical transmitter-receiver mounted thereon is split into several parts, the fixing position of which respective parts with regard to the housing is set according to the standardized size of the respective components and which respective parts are interconnected through an electric connector and so forth, which makes the height of the transmitter-receiver lower. The split circuit boards are overlapped such that they make no contact with one another so as to enlarge the area of the circuit boards or practically increase the packaging area of the respective components, which realizes the structural compactness of the optical transmitter-receiver. The packaging side of the respective components is selected in an arbitrary manner according to the cooling direction of the respective ICs, which allows such direction to be oriented to the side of the heat sinks so as to enhance cooling behavior. When deteriorated parts are found, only the circuit board with such parts mounted is removed for repair or replacement, resulting in improving productivity and reducing production cost.
摘要翻译：安装有其上的光收发器 - 接收器的各个部件的印刷电路板分成若干部分，根据各部件的标准尺寸设定相对于外壳的相应部件的固定位置，通过电连接器等互连，这使得发射机 - 接收机的高度降低。分离电路板重叠，使得它们彼此不接触，以便扩大电路板的面积或实际上增加各个部件的封装面积，这实现了光发射机 - 接收机的结构紧凑性。各个部件的封装侧根据各IC的冷却方向以任意的方式进行选择，这允许这样的方向定向到散热片的侧面，从而增强冷却性能。当发现劣化部件时，只有安装了这些部件的电路板被拆除以进行修理或更换，从而提高生产率并降低生产成本。
