We summarize our recent results on field trial of optical burst switching node prototype developed under NEDO-funded Photonic Network Project. Stable switching and transmission of 40/10-Gbps mixed-bitrate signals are achieved over 92-km 2-hop field testbed.
We developed an optical burst switching (OBS) network testbed with three nodes, where each node consisted of a fast 5 5 (Pb,La)(Zr,Ti)O optical matrix switch. A newly developed Ether frame media converter was successfully used to evaluate Layer-2 performance of the testbed, with a line rate of 40Gb/s. A dynamic deflection routing scheme for contention resolution is implemented. Error-free switching...
Multi-hop cascadibility of a PLZT matrix switch-based optical burst switching node prototype is presented. Using a 50 km recirculating loop setup and a 4times4 matrix switch, more than 10 hop transparency at 10 Gb/s was achieved. Hop-by-hop wavelength conversion for contention resolution and signal reshaping effect was confirmed.
