Abstract

This paper highlights the limited power penalty condition of OXADM that effect the number of maximum nodes that can be cascaded in optical network. If the limited power penalty condition is violated, the power penalty will become infinity. The condition for limited power penalty for OXADM occur when incoherent crosstalk multiply with the number of maximum nodes; (MN-1)L. Therefore the value must be less than 174, otherwise it will become infinity. It was found that as the number of ports and number of carriers increase, the number of maximum nodes decrease. When compared with conventional OXC device, it was found that the number of maximum nodes for OXC is larger than OXADM. This is due to large power penalty in OXADM. In addition, the accumulation function in OXADM reduces the scalability of this device. The objective of this paper is to study the limited power penalty condition of OXADM in order to avoid infinity. In addition, according to the limited power penalty condition, the relationship between number of maximum nodes against number of ports and number of carriers are also studied. Hence, the results are compared with conventional OXC device.
