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 or at least two lens basic units arranged in an one-dimensional array. The lens basic units are formed by arranging a number of single lenses 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 or that of the lens basic units is no less than the cross-sectional area of a single optical fiber.
Claims9
An optical switch for large-capacity optical fiber program-controlled exchanges, wherein optical transmission among optical fibers is performed through a reflection of lasers by a lens part of digital micro-minor device (DMD) chips;
- the lens part of the DMD chips consists of at least twenty single lenses arranged in an one-dimensional array when the optical fibers are single-mode optical fibers or at least twenty lens basic units arranged in an one-dimensional array when the optical fibers are multi-mode optical fibers;
- the lens basic unit is formed by arranging a number of single lenses in an n×n matrix, wherein 2≤n≤10;
- the one-dimensional array is arranged in such a direction that the lasers do not interfere with each other after reflection;
- and an area of the single lenses or that of the lens basic units is not less than the cross-sectional area of a single optical fiber,
- wherein the optical transmission among the optical fibers through the DMD chips is a bi-directional transmission,
- wherein the one-dimensional array is an orderly arrangement in an one-dimensional space.
