This invention relates to an optical switch with an arbitrary port number and its arrangement method for the optical communication system, and switches an optical path by using mirrors. The invention uses a network exchange algorithm to compute crossing points and reflecting points of the optical paths. Single-sided reflecting mirrors are disposed at the reflecting points of the optical path respectively, and double-sided reflecting mirrors are disposed at the crossing points of the optical path respectively. With the arrangement method, the arbitrary port number optical switch can be applied to satisfy the requirement for an arbitrary number of input and output terminals, so as to assure that an equal length of each optical path and to decrease the number of mirrors to minimize the cost, size and assembling time of the optical switch.
