Abstract
Reduced configuration Optical Cross-Connect (OXC) switches can include N inputs to the OXC switch and N outputs from the OXC switch, where N is at least 3. The N.times.N OXC switch provides N! states, wherein the N! states optically couple any one of the N inputs to any one of the N outputs. The N.times.N OXC switch also includes a number of switching nodes that are selectively optically coupled to the N inputs and N outputs. Each of the number of switching nodes is configurable in at least one of a switching configuration and a pass-through configuration to provide selectively switched optical radiation therefrom and wherein the number of switching nodes is equal to ceiling [ln(N!)/ln(2)] to provide the N! states of the N.times.N OXC switch. The N.times.N OXC switch further includes at least one optical transmission apparatus coupled to at least two of the switching nodes. Related methods are also disclosed.
