Optical Network Restoration and Migration Using OXADM
Source: Universiti Kebangsaan Malaysia
Optical Cross Add and Drop Multiplexer (OXADM) is a recently invented optical networks device. Designed with a purpose to combine the operational concepts of Optical Cross Connect (OXC) and Optical Add-Drop Multiplexer (OADM), OXADM is potentially useful in increasing the efficiency and flexibility of optical networks particularly of the metropolitan ring and mesh configurations. The OXADM node focuses on providing the functions of transportation, multiplexing, routing, supervision, termination and survivability in the optical layer for both ring and mesh topologies. Thus, OXADM is particularly of use for networks which require topology migration from ring to mesh, or vice versa.
