A kind of manufacturing method of cwdm special optical module

Abstract

The invention discloses a manufacturing method of a CWDM special optical module. The method comprises the following steps that 1, a module is installed, specifically, an installation module is taken out, and a control switch is turned on to enable an electric telescopic rod to extend, so that a left clamping block and a right clamping block are moved away; 2, a lower shell is installed, specifically, a control switch is turned on, the installation module in the step 1 is conveyed right above a lower shell telescopic rod, at the same time, the lower shell telescopic rod extends, and the lower shell is jacked up to the bottom of the installation module; and 3, an upper shell is installed, specifically, an upper shell telescopic rod works, the upper shell is pushed to fall into an installation groove, and then the upper shell is clamped with a lower shell assembly part. The manufacturing method relates to the technical field of electronic components. According to the manufacturing method of the CWDM special optical module, the installation module adapted to a PC board and an electronic component assembly is arranged, and only the assembly needs to be clamped in the installation module, so that the automatic installation can be realized, the finishing efficiency is improved, a large amount of labor is also saved, and meanwhile, the mechanical dimension is accurate, and the product installation quality is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a manufacturing method of a CWDM special optical module. Background technique [0002] CWDM is a low-cost WDM transmission technology for the access layer of the metropolitan area network. In principle, CWDM uses an optical multiplexer to multiplex optical signals of different wavelengths into a single optical fiber for transmission. , with the help of an optical demultiplexer, the mixed signal in the optical fiber is decomposed into signals of different wavelengths, and connected to the corresponding receiving device. The function of the optical module is simply photoelectric conversion. After transmission, the receiver converts the optical signal into an electrical signal. [0003] The optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include two parts: transmitting and receiving. For the ...
