Abstract:
1. A single-fiber bidirectional optical module comprising: a transmitter including a laser diode for generating transmission light and transmitting the light through an optical fiber; a receiver including a light receiving element for receiving reception light transmitted through the optical fiber; a wavelength selective filter obliquely provided on an extension line of the light path of the optical fiber for separating the reception light and the transmission light from each other; a metal chassis for holding the laser diode, the wavelength selective filter, and the light receiving element; a receptacle for removably holding the optical fiber for bidirectionally transmitting the transmission light and the reception light; and an insulative member for holding the receptacle to be electrically insulated from the chassis, wherein the chassis is held at a receiver ground RG, and the anode and the cathode of the laser diode are insulated from the chassis.
