Optical Code Division Multiple Access (OCDMA) is one of the most upcoming technologies for future multiple access techniques along with WDMA and OTDMA. Optical CDMA offers greater scalability than other optical multiplexing technique and it provides flexible quality of service and data access security. OCDMA requires increasing demand for high speed, large capacity communications in optical networks which allow multiple users to share the fiber bandwidth. The data for multiple users are multiplexed asynchronously. In this paper, the authors have presented an OCDMA model to the range of 90km.
