Abstract:	An optical switch including a first reversible optical circulator and a second reversible optical circulator is provided. Each of the first reversible optical circulator and the second reversible optical circulator respectively has four I/O ports, wherein the four I/O ports are respectively a first terminal, a second terminal, a third terminal, and a fourth terminal, the four terminals sequentially transmit an optical signal in a forward circulation or a backward circulation according to a control signal, and an open end is formed between the first terminal and the adjacent fourth terminal. The open ends of the first reversible optical circulator and the second reversible optical circulator are coupled with each other.
