This paper describes our recent approach toward advanced optical layer networks through the development of optical cross add and drop multiplexing (OXADM). The OXADM node focuses on providing functionally such as transport, multiplexing, routing, supervision, terminating and survivability in optical layer with ring and mesh topologies. Thus, OXADM is applicable for those networks that have to be migrated...
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...
