The invention is directed to improved optical crossconnnect switch configurations and implementations. In one embodiment, a beam directing unit (600) includes an input port array (601), input fixed mirrors (604), an input movable mirror array (606), an output movable mirror array (608), output fixed mirrors (610) and an output port array (611). The pitch of the input mirror array (606) is one-half the pitch of the input port array (601) and the pitch of the output mirror array (601) and the pitch of the output mirror array (608) is one-half the pitch of the output port array (611). In addition, in a reference orientation, each of the mirrors of array (606) directs beams to a common centerpoint of output array (608), and each of the mirrors (608) directs beams to a common centerpoint of array (606).
