Abstract :
This article highlights advances in NTT´s optical path crossconnect systems that use planar-lightwave circuit switches. A photonic MPLS router that can handle up to 256 optical label switched paths is developed as one result of our R&D activities; mature OPXC technologies are adopted to create a practical OPXC system.
