Abstract: A cam guiding device includes a cam guide having a cylindrical portion, a partially cylindrical portion extending from a leading end portion of the cylindrical portion, a partially tapered portion extending from the leading end portion of the cylindrical portion, and a rotation stopper portion provided on the partially cylindrical portion, and a sleeve for accommodating the cam guide. The sleeve includes an arc portion that overlaps the partially cylindrical portion from an outside. A radius of the partially tapered portion increases as the partially tapered portion extends away from the cylindrical portion. The rotation stopper portion is a component that protrudes radially outward from an outer circumferential surface of the partially cylindrical portion. When the rotation stopper portion abuts the sleeve and an inner circumferential surface of the cam guide abuts the parking cam, rotation of the cam guide with respect to the sleeve is restricted.

Abstract: A transmitter optical subassembly may include an optical modulator for modulating output light from the light source. The optical modulator has a characteristic that a current depending on amount of optical absorption has a positive correlation with an applied voltage thereto. The transistor at the second terminal is connected in series to the optical modulator. A drive voltage applied to the optical modulator and the transistor is divided into a first voltage applied to the optical modulator and a second voltage applied to the transistor. A drive current flowing through the optical modulator and the transistor depends on the control signal input to the first terminal. The first voltage is based on the drive current and is subject to the characteristic of the optical modulator. The second voltage fluctuates in response to the first voltage.
