Abstract

The invention discloses an optical module. The optical module comprises a circuit board and a lens assembly, wherein an optical transmitter and an optical detector are integrated with the circuit board; the lens assembly is covered above the optical transmitter and the optical detector; a first plane of reflection, a second plane of reflection and a third plane of reflection are formed in the lensassembly; a light beam irradiated on the first plane of reflection is propagated in a first direction after reflection; after a light beam irradiated on second plane of reflection is reflected, the light beam is irradiated on the third plane of reflection in a second direction, is propagated in a third direction after being reflected on the third plane of reflection, and then is incident in the optical detector; and the included angle between the first direction and second direction is 80-100DEG. The optical module reduces the process of manufacturing and increases the stability of product.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to an optical module. Background technique [0002] Optical modules are used for photoelectric signal conversion. Generally, during the operation of the optical module, it is necessary to monitor the laser of the optical module to know the working state of the laser. In the traditional technology, a spectroscopic device, such as a filter, is usually placed on the exit direction of the laser to split the beam emitted by the laser into two paths, one of which is transmitted through the spectroscopic device and coupled to the optical fiber, and the other path passes through the spectroscopic device The reflection is incident to the detector of the optical module, and the detector receives the reflected beam and detects the optical power parameters, thereby realizing the monitoring of the state of the laser. [0003] However, the above-mentioned monitoring method needs to add an a...
