Abstract: An optical switch is configured in a “dual-ganged” switch geometry to provide for the simultaneous switching of a selected transmit/receive pair of optical signal paths between a specific optical communication device and an optical communication network. A biaxially-symmetric signal redirection component may be used to direct the signals between the selected channel and the optical communication device. A specific waveguide (e.g., fiber) array topology within the dual-ganged switch (DGS) breaks the symmetry between the network transmit/receive arrays and a pair of transmit and receive signal paths associated with the communication device to improve isolation and minimize the possibility of cross-talk between non-selected waveguides in the transmit and receive arrays. The possibility of “hits” during switching between channels can be eliminated, and is controlled by dictating the process or switching steps used to rotate the biaxially-symmetric signal redirection element.
