This paper introduces a new optical device model named as an optical cross add and drop multiplexer (OXADM) which has potential use in CWDM metro area networks. The device uses the concepts of combination of optical add/drop multiplexing and optical cross connect between two main transmission lines in order to implement the wavelength routing operation [10]. MEMS optical switches are integrated in...
We demonstrate a newly invented device named as optical cross add and drop multiplexer (OXADM) which designed with a combined concept of optical cross connect (OXC) and optical add drop multilexer (OADM). It is designed by improving all drawbacks appear in the previous device with some interesting features added. The OXADM node focuses on providing functionalities of transport, multiplexing, routing,...
The provision of acceptable service in the presence of failures and attacks is a major issue in the design of next generation dense wavelength division multiplexing (DWDM) networks. Survivability is provided by the establishment of redundant lightpaths for each connection request to protect the primary lightpaths. This paper presents a genetic algorithm (GA) solver for the routing and wavelength assignment...
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...
