摘要：
To achieve a size-reduction of an optical module having a circuit that generates a high-frequency clock signal for controlling optical modulation by an optical modulator and to suppress radiation of electromagnetic waves from the optical module. A through-hole via is formed on a multilayer printed circuit board so as to be insulated from a plurality of grounded wiring layers by an anti-pad. A coaxial connector and an intensity modulation control IC that generates a high-frequency clock signal are provided on the multilayer printed circuit board. The high-frequency clock signal is input to the coaxial connector through a micro-strip line formed on the multilayer printed circuit board. An open stub connected to the through-hole via is provided on a wiring layer between a first wiring layer and a second wiring layer among the plurality of wiring layers.

为了实现具有生成用于控制光调制器的光调制的高频时钟信号的电路并且抑制来自光模块的电磁波的辐射的光模块的尺寸减小。 在多层印刷电路板上形成通孔通孔，以便通过防焊垫与多个接地布线层绝缘。 在多层印刷电路板上设置同轴连接器和产生高频时钟信号的强度调制控制IC。 高频时钟信号通过形成在多层印刷电路板上的微带线输入到同轴连接器。 在多个布线层中的第一布线层和第二布线层之间的布线层上设置有与通孔孔相连的开放短截线。
