Research and Simulation of OCDM Switch Layer Based on 2D WDM-Optical Code Switching Structure

Abstract Optical Communication is widely used in military and civilian backbone network communication, but due to the limitation of “electronic bottleneck”, ability nodes process information optical layer data transmission capacity seriously mismatched, which directly causes cross connectors nodes. The number ports carried has skyrocketed. In order improve processing speed nodes, this paper studies four-layer multi-granularity switching system fiber, wavelength band, wavelength, code, finally builds a complete OCDMA through simulation software, simulates multi-user simulation, successfully realizes encoding decoding analyzed, performance analysis core module multi-layer system-OCDM are out, feasibility superiority selected verified.
