Multiple Optical Label that generated by combining multiple optical orthogonal codes (MOOC) in serial can increase the quantity of available labels. An optical packet switching (OPS) system adopting MOOC label is demonstrated, and the corresponding techniques including packets generator, label processing, switching control mechanism and switching matrix are discussed. The experiment results of this system realize the packet switching function under the condition of three edge nodes and one core node, and verify the feasibility of the proposed MOOC label scheme.
