ABSTRACT:
An optical transmitting module of a coaxial type is provided in which a disturbance in a waveform of light which is output from a semiconductor laser element due to a signal which is output from an optical modulator unit can be suppressed. The optical transmitting module comprises an optical transmitting package of a coaxial type and a line board (40) connected to the optical transmitting package. The optical transmitting package comprises a semiconductor laser element, an optical modulator unit, and a conductor board (21). A drive current supply line (42) and a common ground line are formed over the line board (40), and a signal attenuation circuit (60) having one end electrically connected to the common ground line and the other end electrically connected to the drive current supply line (42) is provided over the line board (40).
