Abstract
A ribbon array switch in which an input ribbon array comprising a plurality of input optical fibers can be selectively switched to any one of a plurality of output ribbon arrays mounted on an outer periphery of a switch housing. Preferably, the input ribbon is rotated, whereby the input optical fibers will be optically connected to corresponding output optical fibers that make up the output ribbon arrays. Furthermore, the invention features an optical switch architecture including a first stage comprising a fiber switch element and second stage comprising a ribbon array switch element described above. The output optical fibers of the fiber switch element make up the input ribbon array of the ribbon array switch element. The architecture switches an input optical fiber to any one of a plurality of output optical fibers by optically connecting the input optical fiber of the fiber switch element to a selected one of the output optical fibers of the fiber switch element and aligning the input ribbon array of the ribbon array switch element with a selected one of a plurality of output ribbon arrays of the ribbon array switch element. Each output ribbon array comprises a predetermined number of output optical fibers. Accordingly, the output optical fibers of the fiber switch element will be optically connected to corresponding ones of the predetermined number of output optical fibers of the ribbon switch element, and thus the input optical fiber will be optically connected to a desired output optical fiber.
