Abstract:
An optical switch for optical fiber large-capacity stored program control exchanges. Optical transmission among optical fibers is performed through the reflection of lasers by a lens part of DMD chips. The lens part of the DMD chips consists of at least two single lenses ( 1 ) or at least two lens basic units ( 2 ) arranged in an one-dimensional array. The lens basic units ( 2 ) are formed by arranging a number of single lenses ( 1 ) in an n×n matrix, wherein 2≤n≤10. The one-dimensional array is arranged in such a direction that lasers do not interfere with each other after reflection. The area of the single lenses ( 1 ) or that of the lens basic units ( 2 ) is no less than the cross-sectional area of a single optical fiber. In the optical switch, the DMD imaging technology in the non-communication field is applied to the communication field. The one-dimensional array technology is applied to butt-join the DMD and optical fibers and realize a large-capacity optical switch with the optical fiber switching >5.

Claim (Index 9):
The operating method of the optical switch for large-capacity optical fiber program-controlled exchanges as claimed in  claim 8 , wherein in step (2), the DMD chips are arranged by an N-level longitudinal extension to form a DMD chip set, i.e. the input optical fiber transmits lasers to the first-level DMD chip, the rays are reflected from the first-level DMD chip to the next-level DMD chips corresponding to at least three output angels of the first-level DMD chip by rotating the lens part; in this way, the rays are reflected to the Nth DMD chips and finally reflected to the corresponding output optical fibers;\n or, the DMD chips are arranged by transverse extension to form a DMD chip set, i.e. the input optical fiber transmits lasers to one of the DMD chips, the rays reflected by the DMD chip and at least one of at least 3 output angles are reflected to another DMD chip; among the rays reflected by the DMD chip, the rays reflected at least one angle are reflected to another DMD chip, and the rest rays are reflected to the corresponding output optical fibers, thus the incident rays are transversely extended; or, the DMD chip set formed by an N-level longitudinal extension and the DMD chip set formed by transverse extension are butt-joined to form an optical fiber crossbar program-controlled exchange or router.
