A free-space N by M where N and M > 1 optical signal switch (OXC) requires only transmitter beam steering for controlling to which receiver an optical signal from a transmitter is directed. In a preferred embodiment the transmitters handle single mode optical signals and the receivers handle multimode optical signals. The OXC may optionally include a fixed optical unit implemented using either a single fixed shared lens or a plurality of M optical elements for further directing each of the M optical signals to their respective receivers.
