Optical module |
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.
