1:8-mechanical Optical Protection Switch Design And Assembly

With the rapid development of the optical transmission network, the capacity ofnetwork increases continually. The fault protection and fault recovery ability of thetransmission network become key functions. While the protection operation of opticalswitch on optical layer Plays an important role in the transmission network. Therefore,the design and development of1:8-optical switch used in network protection arestarted.Based on the application of1:8-optical switch, the optical path, the shellencapsulation, the internal structure, and technological process of the switch aredesigned in this thesis. The optical path structure of the switch is realized by using theway of free space. The structure makes design of the light path more flexible, switchstructure more simple, smaller crosstalk between channels, volume more compact.When parameters of optical device are designed, the influence of the parameters onproperties of the switch is analysed in detail.Sealed packaging ensure the wet resistance of the switch. Among them betweenshell and plate, parallel sealing way of packaging, A kind of resistance welding isused. With the way of welding, good sealing performance between the shell and platecan be got through setting reasonable welding parameters. When the shell assemblystructure is designed, the standardization of assembly process and the production costare considered. The precision template and auxiliary equipment designed is used forassembly process. The design analysis of the influence of the production cost have beembodied in this paper some locationThe production process of optical switch is designed, and the key process isstated in detail. In according to the performance test results of the sample, the processis appropriately adjusted.
