Problems solved by technology
[0002] In the prior art, the optical transceiver module interface assembly (BOSA) using the isolator, the isolator is installed on the laser tube cap, because the distance between the isolator and the laser is very close, the aperture of the isolator needs to be relatively large, and the light emitted by the laser passes through The loss of the isolator can meet the requirements, and the cost of the isolator with a large aperture is relatively high, which affects the product cost
In addition, the alignment and fixation of the traditional structure isolator and the laser is difficult, and the loss of the light emitted by the laser through the isolator is relatively large

The invention discloses an interface assembly of an optical transceiver module. The interface assembly comprises a laser device, an isolator, a spectroscopic plate fixing seat, a 45-degree spectroscopic plate, a ceramic ferrule, a zero-degree spectroscopic plate and a detector. The laser device, the isolator, the spectroscopic plate fixing seat, the 45-degree spectroscopic plate and the ceramic ferrule are sequentially placed on the same horizontal light path, and the zero-degree spectroscopic plate and the detector are sequentially placed on a vertical light path of the 45-degree spectroscopic plate. The isolator is mounted on the spectroscopic plate fixing seat, so that loss of light which emitted by the laser device after the light passes through the isolator with small clear aperture is low. The interface assembly of the optical transceiver module is low in cost, and an operation process of the interface assembly is convenient.
Description
technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an interface component of an optical transceiver module. Background technique [0002] In the prior art, the optical transceiver module interface assembly (BOSA) using the isolator, the isolator is installed on the laser tube cap, because the distance between the isolator and the laser is very close, the aperture of the isolator needs to be relatively large, and the light emitted by the laser passes through The loss of the isolator can meet the requirements, and the cost of the isolator with a large aperture is relatively high, which affects the product cost. In addition, it is difficult to align and fix the traditional isolator and laser, and the loss of the light emitted by the laser through the isolator is relatively large. [0003] Therefore, a new technical solution is needed to solve the above problems. Contents of the invention [0004] Aiming at th...
