Abstract: The characteristics of different access techniques used in optical network are analyzed and compared. A new optical network with Wavelength Division Multiplexing and Optical Code Division Multiplexing Access (WDM/OCDMA) is presented. The advantages and applications of this network scheme are discussed. In the end, the network structure of this WDM/OCDMA network and the optical CDMA encoding and decoding schema are introduced. The results show that the WDM/OCDMA network, which can fully use the advantages of WDM and OCDMA technologies, is valuable in practice.
