The paper presents an efficient CAD algorithm for the design of waveguide front-end diplexers. Three different types of junctions can be employed: E-plane T-junction, H-plane T-junction and E-plane bifurcation. Channel filter configurations currently include — but are not limited to — waveguide stub filters and inductive-iris filters. The diplexer design is performed in three basic steps: synthesis,...
We propose a flexible and resilient SDN-controlled hybrid optical/electrical intra-DCN architecture employing low-cost distributed optical switches. Significant delay reduction as well as automatic flow path setup and restoration are demonstrated using real-time traffic over an experimental OpenFlow-based testbed.
A conventional colorless and directionless reconfigurable optical add/drop multiplexer (ROADM) architecture is modified to add intra-node optical bypass and achieve either statistical or absolute contention-free performance. The contention-free performance is accomplished without relying on external transponders and optical transport network (OTN) switches. Furthermore, the overall ROADM has a smaller...
A conventional colorless and directionless ROADM architecture is modified to achieve contention-free performance without relying on external transponders and OTN switches, and can achieve a smaller size and lower power consumption than those of a conventional CDC ROADM.
We propose a hierarchical multi-granular switch architecture in FWDM networks, and investigate the routing, spectrum allocation, and waveband assignment problem. Hierarchical switching can improve cost and energy efficiencies while marginally sacrificing spectral efficiency.
