Problems solved by technology
[0003] However, the product size of the combo pon optical transceiver device using this package structure is relatively large, so there is little room for circuit board layout design in the optical module, resulting in the need to adopt a dual circuit board structure design, which increases the module size and cost, and does not require Conducive to meet the requirements of miniaturized packaging
Moreover, there are many components and the production process is cumbersome and complicated, and each additional material or one additional step of the production process will introduce deviations in the material itself or process operation deviations, which will lead to a decrease in coupling efficiency, and comprehensive superposition will lead to a high product defect rate

The invention discloses an optical device which comprises a metal shell, one end of the metal shell is provided with a square airtight cavity used for mounting a transmitting assembly, the other end of the metal shell is provided with a containing cavity used for containing a wave splitting and combining assembly and an outlet used for being fixedly coupled with an adapter, and the side portion of the containing cavity is further provided with a receiving assembly mounting opening. A light window used for emitting light of the emitting assembly is arranged between the square airtight cavity and the containing cavity, and the airtight cavity is provided with a matched sealing cover. And the receiving component mounting port is provided with a receiving TO component. The invention further discloses a production coupling method of the optical device. Through the structure and the coupling method, loss can be reduced, and high coupling efficiency is obtained.
Description
technical field [0001] The invention belongs to the technical field of optical devices, in particular to an optical device, and also to an optical device and a production coupling method. Background technique [0002] In the optical communication network, in order to save optical fiber resources and meet the transition requirements of forward and backward compatibility in the process of passive optical network (Passive optical network, PON) bandwidth upgrade, the hybrid passive optical network combopon scheme is adopted, that is, in one device Set up two sets of optical components respectively. The specific structure generally adopts the combined packaging method of four discrete devices, that is, two TO-packaged laser emitters and two TO-packaged detectors are respectively welded to a metal tube body, and a filter with a specified angle is set in the metal tube body. The chip is used to realize the demultiplexing and sharing of the four wavelength signals and share one opt...
