A differential transmission line includes a first differential transmission line, which has a first characteristic impedance and is connected to a drive IC, a second differential transmission line, which has a second characteristic impedance and is connected to a light output element, the second characteristic impedance being smaller than the first characteristic impedance, and connecting portions configured to connect the first differential transmission line and the second differential transmission line in series with each other. A resistive element is arranged between the connecting portions. The resistive element has a resistance value that is set to a value with which an absolute value of a reflection coefficient for a signal traveling from the second differential transmission line side to the first differential transmission line side is 0.10 or less."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical module and optical transmission device","description":"In an optical module, optical signal output having satisfactory waveform and intensity can be obtained.
