Optical module

The invention discloses an optical module. One end of a housing is provided with an optical fiber adapter; and the housing is internally provided with a laser chip, a first filter, an optical isolator, a reflector plate, a reflecting prism assembly, a light receiving chip and an optical platform. A boss of the optical platform is provided with a first through hole; the optical isolator is arrangedin the first through hole; a first inclined plane is formed on the rear surface of the boss; and the first filter is arranged on the first inclined plane. An optical signal emitted by the laser chipsequentially passes through the optical isolator and the first filter, enters the optical fiber adapter and then, is emitted out. The reflector plate is located on the platform of the optical platform. The optical signal from the optical fiber adapter is reflected by the first filter to the reflector plate, and the generated reflected light is reflected to the light receiving chip through the reflecting prism assembly.
