Example Embodiment
[0039] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be pointed out that for those of ordinary skill in the art, a number of modifications and improvements can be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0040] figure 1 The logical structure diagram of the non-blocking expansion system based on multiple disjoint unidirectional optical fiber ring networks provided by the present invention is given, including three stages of input stage, intermediate stage and output stage. The system is logically equivalent to a non-blocking expansion system. Cyprus’s three-level Clos network; among them,
[0041] The input stage and output stage are composed of air separation switching modul...
