n Working Principle
The 3-D1×2 configuration consists of either three sets of dual 1×2 or six sets of 1×2 fiber structures, forming a 6×12 optical switch. The working principle of the manually switched optical switch is based on a precision mechanical structure design. When an external manual control signal acts on the switch, it drives internal mechanical components (such as micro-motors or spring plates) to move, thereby altering the path of the optical signal. Specifically, when an input optical signal enters the switch, it is directed to one of the two output ports according to the state of the manual control signal, achieving switching and distribution of the optical signal.
Furthermore, there is another type of 6×12 optical switch based on the Faraday effect. This switch contains no moving components internally. It utilizes the principle of electromagnetic induction and the Faraday rotation effect to change the polarization state of the incident light beam. Combined with a birefringent polarizing beam splitter crystal, this alters the propagation path of the light beam, thereby enabling optical path switching functionality.
