Abstract
Systems and methods for optimizing port usage in an optical circuit switch are disclosed herein. A plurality of optical circulators can be coupled to the plurality of input and output ports of an optical circuit switch. An optical circulator coupled to an input port and an optical circulator coupled to an output port can form a bidirectional pair capable of communicating with any other bidirectional pair of the optical circuit switch. In this regard, the number of bidirectional ports of an optical circuit switch can be increased allowing additional bandwidth to flow through the optical circuit switch. Increasing the efficiency and capabilities of optical circuit switches within a large scale communications network can offer increased functionality and performance with little trade off.
