Abstract
An L-dimensional optoelectronic switch for transferring an optical signal from an input device to an output device, the optoelectronic switch includes: a plurality of leaf switches, each having a radix R, and arranged in an L-dimensional array, in which each dimension i has a respective size R(i=1, 2, . . . , L), each leaf switch having an associated L-tuple of co-ordinates (x, . . . , x) giving its location with respect to each of the L dimensions; wherein each leaf switch is a member of L sub-arrays, each of the L sub-arrays associated with a different one of the L dimensions, and including: a plurality of Rleaf switches, whose co-ordinates differ only in respect of the idimension, each leaf switch having C client ports for connecting to an input device or an output device, and F fabric ports for connecting to spine switches; a plurality of Sspine switches, each having R fabric ports for connecting to the fabric ports of the leaf switches, and wherein, in a given sub-array each leaf switch in the sub-array is connected to each spine switch via an optical active switch.
