Analysis of 6× 40Gbps Symmetric Next Generation OCDMA-PON with Modified ZCC Code

The promising optical code division multiple access (OCDMA) has a number of benefits over conventional multi-access techniques, including as ease, better resource utilization, asynchronous operation, and the capacity to offer distinct Quality of Service classes for separate users. In this paper, a full-duplex <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6× 40Gbps</tex> OCDMA-passive optical network (PON) model comprising modified zero cross correlation (ZCC) code is proposed. The results indicate that the model offers 220-300km range at high aggregate throughput of 240Gbps. It also supports 60-100 users for code weight of 1-64. At optimum launch power of −3 to −6.5dBm, the performance of the model can be improved in both directions. The obtained eye patterns are also realized to indicate the system performance for 50-300km range. Compared to recent literature the designed model indicates the superiority.
