    摘要： The present invention provides an optical transmission module having a laser diode that generates laser beams and a differential type current switch provided with a first switch and a second switch in order to supply a modulating current to the laser diode. A terminal of the laser diode and the first switch are connected in series through a first transmission line and a first capacitor, the other terminal of the laser diode and the second switch are connected in series through a second transmission line and a second capacitor. The current driven by the second switch is terminated by a resistor connected to the first switch and the current driven by the first switch is terminated by a resistor connected to the second switch. Thus, the laser diode is modulated bidirectionally.

    摘要： A flexible printed circuit board has an insulation layer, a first signal wiring layer including a microstrip line, a second signal wiring layer including a signal connection terminal for allowing the microstrip line to connect the exterior connector electrically, and a ground conductive section having a ground connection terminal for connecting the exterior connector. The microstrip line and the signal connection terminal are connected to each other by a wiring via hole. The wiring via hole passes through the insulation layer, the first signal wiring layer, and the second signal wiring layer. The microstrip line has a taper section which gradually enlarges a width of the microstrip line toward the wiring via hole in the vicinity of the wiring via hole. The ground conductive section that corresponds to the microstrip line has a taper section with a shape matching the taper section of the microstrip line.
