The optical code-division multiplexing routing system allows the label and payload information to be processed in parallel. But going with the label converting, the payloads also accumulate in the optical buffering area, which causes Multi-access interference, when the light pulses of many users are simultaneously transmitted. The multi-user interference is the main noise factor of the edge router. In this paper, the performance of the system with and without Optical Hard-limiter on the impact of the multi-user interference is analyzed theoretically, showing that we can effectively reduce the influence of multi-user interference, increase the system capacity, and improve the bit error performance of the system by adopting an optical hard-limiter.
