Abstract: A MEMS optical switch and a switching node are disclosed. The MEMS optical switch includes N1 input ports, N1 input MEMS mirrors, M1 output ports, and M1 output MEMS mirrors, where a first input port is configured to transmit a first optical signal to a first input MEMS mirror. The first input MEMS mirror is configured to reflect the first optical signal to a first destination output MEMS mirror, where along a straight line in which a first deflection axis is located, the first input MEMS mirror is located on an edge of the N1 input MEMS mirrors, and when reflecting the received first optical signal to a first output MEMS mirror and a second output MEMS mirror, the first input MEMS mirror deflects towards an opposite direction relative to a second deflection axis.
