Abstract
An apparatus and method for routing optical signals between a pair of input ports and a pair of output ports is provided. An optical switching arrangement adapted to shift among at least two distinct optical configurations is provided for directing the optical signals. In the first configuration, the optical signal from the first (second) input port is directed to the first (second) output port. In the second configuration, the optical signal from the first input port is discarded and the optical signal from the second input port is directed to the first output port.
