We demonstrate multi-failure restoration in optical layer by using an eleven-node multi- vendor WSON test-bed. Automatic restoration is achieved by deploying colorless and directionless optical switching equipments with WSON-enabled control plane.
We demonstrate highly resilient wavelength path recovery within 2.0 seconds from each of triple failures, and 2.0 seconds from simultaneous failures. It is achieved, at first time, by interoperable dynamic wavelength path control in multi-vendor optical WDM networks.
We present the first experimental demonstration of a multi-granularity optical-cross-connect node toward 100-Tbit/s scalability. We successfully show 10.24-Tbit/s throughput with completely error-free operation and an 80-Gbit/s (2 times 40-Gbit/s) optical-virtual-concatenation function between different routes.
We developed a compact 8 times 8 gate switch subsystem, which was integrated with eight 8:1 SOA modules (72-SOAs). We achieved a high-speed switching, lossless and colored operation.
To enable automatic operation of a network where PXC(Photonic Cross Connect) is applied, a novel mechanism is proposed which discovers optical fiber links between the nodes.
