Background
In optical fiber network systems, the transmission of information is accomplished by the transmission of optical signals in optical fibers. In the process of information transmission, signals of different channels are usually required to be switched, so that the requirement of cross-switching optical switches is promoted. The mechanical optical switch is an electro-optical switch which adopts a mechanical moving element to realize the switching of different signals among channels. Optical moving elements commonly employed in mechanical optical switches include triangular prisms (CN 1427277 a), double parallelogram prisms (CN 202093205U), trapezoidal prisms (CN 103487893A), plane mirrors (CN 1215348C), and diamond prisms (CN 2507021Y). Among them, a diamond prism is commonly used in early stages to switch the collimated light paths of two parallel light beams (as shown in fig. 1). However, this solution has the drawback of being large in size.

Further, the 1×4 optical switching scheme is as follows: one of the optical fiber collimators is a TEC single optical fiber collimator, the other optical fiber collimator is a TEC four optical fiber collimator, one side of the TEC single optical fiber collimator is drilled with a circular hole, and two sides of the TEC four optical fiber collimators are respectively drilled with a circular hole; the number of the diamond-shaped silicon wafers is three, one diamond-shaped silicon wafer is positioned in the TEC single-fiber collimator, and the other two diamond-shaped silicon wafers are respectively positioned in the TEC double-fiber collimator; the three diamond-shaped silicon chips are respectively controlled by the corresponding electromagnetic relays to translate up and down, so that the 1X 4 cross switching of the optical paths is realized.
