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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical module","description":"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 e","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8467118","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
