Non-Winding AODF Cross-Connect Method Based on the Spatial Relationship of Non-Coplanar Lines

Abstract

Outdoor communication wiring is mainly used to provide a physical connection between telecommunication services. With many fibers to the X networks having been built to provide high-level reliability services and to reduce operational costs, the operator has a strong demand for an automatic optical distribution frame. Based on the mathematics of knots to study the relationship of the fiber-optic connections on the main distribution frame, we proposed the “HIGHER ALWAYS ON TOP” method for fiber-optic switching. Two prototypes of a 1-D array of input lines and a 1-D array of output lines use a line match line and a line match circle to demonstrate these concepts. We proposed the method of constructing non-coplanar lines in a 1-D array of input lines and a 2-D array of output lines, as well as a 2-D array of input lines and a 2-D array of output lines, for scalability. We imitated the opening of a shuttle in the textile field and proposed a high-speed cross-connect method and a simulation experiment to show its feasibility.
