Description
Summary:The optical cross add and drop multiplexing (OXADM) device described in this paper increases the capacity, flexibility and reliability of the trunk-line optical network used for data communication. It features two different bandwidths which operate in working and protection line in a ring configuration. The OXADM has the same features of the conventional OADM node but with more efficiency and reliability. The OXADM prototype system focuses on providing survivability through restoration against failures, such as cable/fiber cut in optical layer with ring topology. Two types of restoration scheme have been proposed to ensure data flow continuously by means of linear/multiplex protection and ring protection. This paper describes the analytical modeling of OXADM and studies their limitation as compared with conventional OXC device.
