Abstract
A switch module and optoelectronic switch incorporating the same. The optoelectronic switch includes an N-dimensional array of switch modules arranged in a topology in which each switch module is a member of N sub-arrays, the sub-arrays defined with reference to the coordinates of the constituent switch modules, and wherein all of the members of each sub-array are connected by an active switch, which in some embodiments may be an optical active switch or an electronic active switch.

1-24. (canceled)
A switch module, for use in an optoelectronic switch, the switch module having:
- a client portion for connecting to an input device or an output device;
- and
- a first fabric portion having a transmission side and a receiving side,
- the transmission side having:
- a transmission side input;
- a transmission side packet processor configured to receive, at the transmission side input, a first electronic signal, and to produce, at a plurality of outputs of the transmission side packet processor, a plurality of respective first electronic component signals;
- a plurality of transmission side electrical to optical converters for converting each of the first electronic component signals into a respective optical signal of a first plurality of optical signals;
- a transmission side multiplexer for converting the first plurality of optical signals into a multiplexed fabric output signal, and
- the receiving side having:
- a receiving side demultiplexer for receiving a multiplexed fabric input signal and separating said multiplexed fabric input signal into a second plurality of optical signals;
- a plurality of receiving side optical to electrical converters for converting each of the second plurality of optical signals into a respective second electronic component signal of a plurality of respective second electronic component signals;
- a receiving side output;
- and
- a receiving side packet processor configured to receive, at respective inputs of the receiving side packet processor, the second electronic component signals, and to transmit, at the receiving side output, a second electronic signal.
