It is welded into the 4th assembly；Pass through laser welding after 4th assembly, the first regulation ring and first laser device TO-CAN couplings
Together.
Compared with prior art, the utility model has the advantages that：The utility model is by the branch of metal shell, the first filter plate
Frame and optoisolator support Design are integrated, and optoisolator and the first filter plate are fixed on inside metal shell by roasting glue, light
Isolator is that two laser TO-CAN are shared, and integral device structure is more simplified, realizes single isolator (two transmitting terminals share)
The coupling package of structure, and can be with step-less adjustment optical device length；Independent filtering plate rack passes through interference fit and roasting glue mode
Seamless welding is realized with metal shell and the assembling of insulating optical fiber coupling assembly.The utility model is ensureing the situation of lock pin set insulation
Under, it can effectively realize：
(1) single isolator can be common to two transmitting terminals, and the cost of material is low and both ends isolation is all guaranteed；
(2) fiber coupling module position is fixed, and the possibility of the performance change triggered by micro-displacement is relatively low；
(3) detector TO-CAN uses laser welding mode with metal shell, avoids because the expansion of glue hot setting is led
The generation for the bad phenomenon for causing displacement and causing performance to be fallen.
