Flexible waveband routing node architecture for spatial-division and multi-band optical networks [Invited]
We propose a network architecture named flexible waveband routing (FWR) that adopts flexible path bundling and bundled path routing. This two-stage routing scheme can be implemented by a combination of small degree wavelength selective switches (WSSs) and optical matrix switches. As the optical-cross-connect (OXC) scale depends on just that of the matrix switches adopted, large-scale OXC nodes are realized by introducing recently developed high-port-count switches. FWR supports spatial division multiplexing efficiently through its introduction of spatially joint switching at WSSs. Multi-band transmission can also be supported by the use of WSSs handling different frequency bands. Numerical simulations and transmission experiments confirm its validity.
期刊介绍：
The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
