Abstract

The invention relates to the field of optical devices, in particular to a 2*2 mechanical optical switch. The 2*2 mechanical optical switch comprises two sets of four-fiber collimators, and glass prisms capable of being freely inserted and separated are arranged among the four-fiber collimators. In the separating state, light beams of a first optical fiber, a second optical fiber, a fifth optical fiber and a sixth optical fiber are directly coupled to a seventh optical fiber, an eighth optical fiber, a third optical fiber and a fourth optical fiber respectively. In the inserting state, after the light beams are deviated through the glass prisms, the first optical fiber is coupled to the third optical fiber, and at the same time, the second optical fiber is coupled to the fourth optical fiber. Besides, the fifth optical fiber is connected with the sixth optical fiber, and the eighth optical fiber is connected with the seventh optical fiber. A bypass loop is formed by leading the light to the other side from one side only through one displacement optical element. Therefore, the dimensionality of optical fiber alignment adjustment can be reduced, larger positions and angle allowances are allowed, the packing difficulty can be reduced, and the 2*2 mechanical optical switch is especially suitable for being produced on a large scale.

Description

technical field [0001] The invention relates to the field of optical devices, specifically a 2×2 mechanical optical switch. Background technique [0002] The optical switch is a device used to control the optical signal to transmit information along the selected optical fiber in the optical fiber network. An ideal optical switch requires low optical insertion loss, good repeatability, long operating life, small size, and low cost. Optical switching devices have become an important part of today's fiber optic networks. [0003] A mechanical optical switch that changes the optical path by moving the light guiding element is widely used in current communication networks. The main reason is that compared with other technologies, the structure of the mechanical optical switch is simple, and the distortion to the transmitted optical signal is small. For example, since current non-mechanical switching technologies are based on changes in optical phase or polarization, these tech...
