Problem statement: Optical Cross Add and Drop Multiplexer (OXADM) is a recently invented optical networks device. Approach: A design with a purpose to combine the operational concepts of Optical Add-Drop Multiplexer (OADM) and Optical Cross Connect (OXC) has been developed. It is developed by studying the drawbacks in existing devices and with some excellence features added. OXADM is introduced to increase the survivability in the ring network. With the ‘Accumulation’ feature and ‘U’ turn reflection enable the multiplex, linear and ring protection scheme activated to ensure the signal arrives at the customer although breakdown occurs in the line and optical node. Beside that with the new features, the topology migration can also be done without the restructuring process due to randomly growth of new nodes. Results: The result shows that; network performance is similar without need a modification on components. Conclusion: Output power and BER performance at different node in ring and mesh optical network are shown to show the achievement of objective.
