A way of making the label and payload en/decoding separate is proposed, and a novel optical code-labeled router, of which routing information can be processed in parallel, is designed based on WDM/OCDM/MPLS technologies. The routing system is composed of 8 paths, and each of them is divided into 8 wavelength channels, being provided by 8 OCDM code words in each channel. The processing speed in every OCDM-path is 1.25 Gbit/s, so the throughout up to 640Gbit/s is achieved. As a platform, optisystem is used to simulate and analyze the routing system. The simulation results show that routing information processing in parallel is feasible. The payloads and labels encoded with two different code words can overlap with each other on the common wavelength. In the core router, the switch processing only includes the short label code recognition so as to increase its processing speed enormously.
