Simulation and Performance Analysis of 2-D Codes at 1 Gbps and 1.25 Gbps Data Rate for OCDMA LAN Applications
Two main forces behind a lot of interest in the OCDMA techniques are the ability to support asynchronous, bursty data transmission and data access security. To achieve high-speed connectivity with a large bandwidth, OCDMA is a highly flexible technique. This paper describes a simulated system for an in-coherent OCDMA system using high performance 2-D codes. In this paper, the authors have designed an OCDMA system for 1 Gbps and 1.25 Gbps using (8x4) wavelength hopped-time spreaded 2-D optical codes. The analysis takes into account the effect of data rate for increasing number of users at different length of fibers.
