Abstract

The invention discloses an optical module, which is characterized in that two opposite end surfaces of a tube body are respectively connected with a light emitting device and an optical fiber adapter, and a first light receiving device and a second light receiving device are arranged on a third end surface and a second end surface which are adjacent. According to the optical module provided by the invention, in a light emission process, signal light at different positions perpendicular to the first end surface has the same incident angle and the same optical path when passing through the first optical filter, and has different incident angles and different optical paths when passing through the second optical filter; signal light at different positions parallel to the first end face has different incident angles and different optical paths when passing through the first optical filter, and has the same incident angle and the same optical path when passing through the second optical filter, so that the first optical filter and the second optical filter have the same influence on the signal light, the generated aberration is the same, astigmatism is avoided, and the coupling efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an optical module. Background technique [0002] The optical module realizes the function of photoelectric conversion in the technical field of optical fiber communication, and the intensity of the optical signal input by the optical module to the external optical fiber directly affects the quality of optical fiber communication. With the development of optical communication technology, optical line terminal optical modules are required to meet higher power budgets, and also increase power requirements for front-end chips, TO and OSA components. Coupling efficiency is particularly important. [0003] In optical component products, the wavelength splitting function is usually achieved by inserting a filter in the optical path, but inserting a filter in the non-parallel optical path for splitting light, because the light rays at different aperture positions of...
